+
+## What is Catch2?
+
+Catch2 is mainly a unit testing framework for C++, but it also
+provides basic micro-benchmarking features, and simple BDD macros.
+
+Catch2's main advantage is that using it is both simple and natural.
+Test names do not have to be valid identifiers, assertions look like
+normal C++ boolean expressions, and sections provide a nice and local way
+to share set-up and tear-down code in tests.
+
+**Example unit test**
+```cpp
+#include <catch2/catch_test_macros.hpp>
+
+#include <cstdint>
+
+uint32_t factorial( uint32_t number ) {
+    return number <= 1 ? number : factorial(number-1) * number;
+}
+
+TEST_CASE( "Factorials are computed", "[factorial]" ) {
+    REQUIRE( factorial( 1) == 1 );
+    REQUIRE( factorial( 2) == 2 );
+    REQUIRE( factorial( 3) == 6 );
+    REQUIRE( factorial(10) == 3'628'800 );
+}
+```
+
+**Example microbenchmark**
+```cpp
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/benchmark/catch_benchmark.hpp>
+
+#include <cstdint>
+
+uint64_t fibonacci(uint64_t number) {
+    return number < 2 ? number : fibonacci(number - 1) + fibonacci(number - 2);
+}
+
+TEST_CASE("Benchmark Fibonacci", "[!benchmark]") {
+    REQUIRE(fibonacci(5) == 5);
+
+    REQUIRE(fibonacci(20) == 6'765);
+    BENCHMARK("fibonacci 20") {
+        return fibonacci(20);
+    };
+
+    REQUIRE(fibonacci(25) == 75'025);
+    BENCHMARK("fibonacci 25") {
+        return fibonacci(25);
+    };
+}
+```
+
+_Note that benchmarks are not run by default, so you need to run it explicitly
+with the `[!benchmark]` tag._
+
+
+## Catch2 v3 has been released!
+
+You are on the `devel` branch, where the v3 version is being developed.
+v3 brings a bunch of significant changes, the big one being that Catch2
+is no longer a single-header library. Catch2 now behaves as a normal
+library, with multiple headers and separately compiled implementation.
+
+The documentation is slowly being updated to take these changes into
+account, but this work is currently still ongoing.
+
+For migrating from the v2 releases to v3, you should look at [our
+documentation](docs/migrate-v2-to-v3.md#top). It provides a simple
+guidelines on getting started, and collects most common migration
+problems.
+
+For the previous major version of Catch2 [look into the `v2.x` branch
+here on GitHub](https://github.com/catchorg/Catch2/tree/v2.x).
+
+
+## How to use it
+This documentation comprises these three parts:
+
+* [Why do we need yet another C++ Test Framework?](docs/why-catch.md#top)
+* [Tutorial](docs/tutorial.md#top) - getting started
+* [Reference section](docs/Readme.md#top) - all the details
+
+
+## More
+* Issues and bugs can be raised on the [Issue tracker on GitHub](https://github.com/catchorg/Catch2/issues)
+* For discussion or questions please use [our Discord](https://discord.gg/4CWS9zD)
+* See who else is using Catch2 in [Open Source Software](docs/opensource-users.md#top)
+or [commercially](docs/commercial-users.md#top).

+## Supported Versions
+
+* Versions 1.x (branch Catch1.x) are no longer supported.

+## Reporting a Vulnerability
+
+Due to its nature as a _unit_ test framework, Catch2 shouldn't interact

+
+Most test frameworks have a large collection of assertion macros to capture all possible conditional forms (```_EQUALS```, ```_NOTEQUALS```, ```_GREATER_THAN``` etc).
+
+Catch is different. Because it decomposes natural C-style conditional expressions most of these forms are reduced to one or two that you will use all the time. That said there is a rich set of auxiliary macros as well. We'll describe all of these here.
+
+Most of these macros come in two forms:
+
+## Natural Expressions
+
+The ```REQUIRE``` family of macros tests an expression and aborts the test case if it fails.
+The ```CHECK``` family are equivalent but execution continues in the same test case even if the assertion fails. This is useful if you have a series of essentially orthogonal assertions and it is useful to see all the results rather than stopping at the first failure.
+
+* **REQUIRE(** _expression_ **)** and
+* **CHECK(** _expression_ **)**
+
+Evaluates the expression and records the result. If an exception is thrown, it is caught, reported, and counted as a failure. These are the macros you will use most of the time.
+
+Examples:
+```
+CHECK( str == "string value" );
+CHECK( thisReturnsTrue() );
+REQUIRE( i == 42 );
+```
+
+Expressions prefixed with `!` cannot be decomposed. If you have a type
+that is convertible to bool and you want to assert that it evaluates to
+false, use the two forms below:
+
+
+* **REQUIRE_FALSE(** _expression_ **)** and
+* **CHECK_FALSE(** _expression_ **)**
+
+Note that there is no reason to use these forms for plain bool variables,
+because there is no added value in decomposing them.
+
+Example:
+```cpp
+Status ret = someFunction();
+REQUIRE_FALSE(ret); // ret must evaluate to false, and Catch2 will print
+                    // out the value of ret if possibly
+```
+
+
+### Other limitations
+
+Note that expressions containing either of the binary logical operators,
+`&&` or `||`, cannot be decomposed and will not compile. The reason behind
+this is that it is impossible to overload `&&` and `||` in a way that
+keeps their short-circuiting semantics, and expression decomposition
+relies on overloaded operators to work.
+
+Simple example of an issue with overloading binary logical operators
+is a common pointer idiom, `p && p->foo == 2`. Using the built-in `&&`
+operator, `p` is only dereferenced if it is not null. With overloaded
+`&&`, `p` is always dereferenced, thus causing a segfault if
+`p == nullptr`.
+
+If you want to test expression that contains `&&` or `||`, you have two
+options.
+
+1) Enclose it in parentheses. Parentheses force evaluation of the expression
+   before the expression decomposition can touch it, and thus it cannot
+   be used.
+
+2) Rewrite the expression. `REQUIRE(a == 1 && b == 2)` can always be split
+   into `REQUIRE(a == 1); REQUIRE(b == 2);`. Alternatively, if this is a
+   common pattern in your tests, think about using [Matchers](#matcher-expressions).
+   instead. There is no simple rewrite rule for `||`, but I generally
+   believe that if you have `||` in your test expression, you should rethink
+   your tests.
+
+
+## Floating point comparisons
+
+Comparing floating point numbers is complex, and [so it has its own
+documentation page](comparing-floating-point-numbers.md#top).
+
+
+## Exceptions
+
+* **REQUIRE_NOTHROW(** _expression_ **)** and
+* **CHECK_NOTHROW(** _expression_ **)**
+
+Expects that no exception is thrown during evaluation of the expression.
+
+* **REQUIRE_THROWS(** _expression_ **)** and
+* **CHECK_THROWS(** _expression_ **)**
+
+Expects that an exception (of any type) is be thrown during evaluation of the expression.
+
+* **REQUIRE_THROWS_AS(** _expression_, _exception type_ **)** and
+* **CHECK_THROWS_AS(** _expression_, _exception type_ **)**
+
+Expects that an exception of the _specified type_ is thrown during evaluation of the expression. Note that the _exception type_ is extended with `const&` and you should not include it yourself.
+
+* **REQUIRE_THROWS_WITH(** _expression_, _string or string matcher_ **)** and
+* **CHECK_THROWS_WITH(** _expression_, _string or string matcher_ **)**
+
+Expects that an exception is thrown that, when converted to a string, matches the _string_ or _string matcher_ provided (see next section for Matchers).
+
+e.g.
+```cpp
+REQUIRE_THROWS_WITH( openThePodBayDoors(), ContainsSubstring( "afraid" ) && ContainsSubstring( "can't do that" ) );
+REQUIRE_THROWS_WITH( dismantleHal(), "My mind is going" );
+```
+
+* **REQUIRE_THROWS_MATCHES(** _expression_, _exception type_, _matcher for given exception type_ **)** and
+* **CHECK_THROWS_MATCHES(** _expression_, _exception type_, _matcher for given exception type_ **)**
+
+Expects that exception of _exception type_ is thrown and it matches provided matcher (see the [documentation for Matchers](matchers.md#top)).
+
+
+_Please note that the `THROW` family of assertions expects to be passed a single expression, not a statement or series of statements. If you want to check a more complicated sequence of operations, you can use a C++11 lambda function._
+
+```cpp
+REQUIRE_NOTHROW([&](){
+    int i = 1;
+    int j = 2;
+    auto k = i + j;
+    if (k == 3) {
+        throw 1;
+    }
+}());
+```
+
+
+
+## Matcher expressions
+
+To support Matchers a slightly different form is used. Matchers have [their own documentation](matchers.md#top).
+
+* **REQUIRE_THAT(** _lhs_, _matcher expression_ **)** and
+* **CHECK_THAT(** _lhs_, _matcher expression_ **)**
+
+Matchers can be composed using `&&`, `||` and `!` operators.
+
+## Thread Safety
+
+Currently assertions in Catch are not thread safe.
+For more details, along with workarounds, see the section on [the limitations page](limitations.md#thread-safe-assertions).
+
+## Expressions with commas
+
+Because the preprocessor parses code using different rules than the
+compiler, multiple-argument assertions (e.g. `REQUIRE_THROWS_AS`) have
+problems with commas inside the provided expressions. As an example
+`REQUIRE_THROWS_AS(std::pair<int, int>(1, 2), std::invalid_argument);`
+will fail to compile, because the preprocessor sees 3 arguments provided,
+but the macro accepts only 2. There are two possible workarounds.
+
+1) Use typedef:
+```cpp
+using int_pair = std::pair<int, int>;
+REQUIRE_THROWS_AS(int_pair(1, 2), std::invalid_argument);
+```
+
+This solution is always applicable, but makes the meaning of the code
+less clear.
+
+2) Parenthesize the expression:
+```cpp
+TEST_CASE_METHOD((Fixture<int, int>), "foo", "[bar]") {
+    SUCCEED();
+}
+```
+
+This solution is not always applicable, because it might require extra
+changes on the Catch's side to work.

+# Authoring benchmarks
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+Writing benchmarks is not easy. Catch simplifies certain aspects but you'll
+always need to take care about various aspects. Understanding a few things about
+the way Catch runs your code will be very helpful when writing your benchmarks.
+
+First off, let's go over some terminology that will be used throughout this
+guide.
+
+- *User code*: user code is the code that the user provides to be measured.
+- *Run*: one run is one execution of the user code. Sometimes also referred
+  to as an _iteration_.
+- *Sample*: one sample is one data point obtained by measuring the time it takes
+  to perform a certain number of runs. One sample can consist of more than one
+  run if the clock available does not have enough resolution to accurately
+  measure a single run. All samples for a given benchmark execution are obtained
+  with the same number of runs.
+
+## Execution procedure
+
+Now I can explain how a benchmark is executed in Catch. There are three main
+steps, though the first does not need to be repeated for every benchmark.
+
+1. *Environmental probe*: before any benchmarks can be executed, the clock's
+resolution is estimated. A few other environmental artifacts are also estimated
+at this point, like the cost of calling the clock function, but they almost
+never have any impact in the results.
+
+2. *Estimation*: the user code is executed a few times to obtain an estimate of
+the amount of runs that should be in each sample. This also has the potential
+effect of bringing relevant code and data into the caches before the actual
+measurement starts.
+
+3. *Measurement*: all the samples are collected sequentially by performing the
+number of runs estimated in the previous step for each sample.
+
+This already gives us one important rule for writing benchmarks for Catch: the
+benchmarks must be repeatable. The user code will be executed several times, and
+the number of times it will be executed during the estimation step cannot be
+known beforehand since it depends on the time it takes to execute the code.
+User code that cannot be executed repeatedly will lead to bogus results or
+crashes.
+
+## Benchmark specification
+
+Benchmarks can be specified anywhere inside a Catch test case.
+There is a simple and a slightly more advanced version of the `BENCHMARK` macro.
+
+Let's have a look how a naive Fibonacci implementation could be benchmarked:
+```c++
+std::uint64_t Fibonacci(std::uint64_t number) {
+    return number < 2 ? 1 : Fibonacci(number - 1) + Fibonacci(number - 2);
+}
+```
+Now the most straight forward way to benchmark this function, is just adding a `BENCHMARK` macro to our test case:
+```c++
+TEST_CASE("Fibonacci") {
+    CHECK(Fibonacci(0) == 1);
+    // some more asserts..
+    CHECK(Fibonacci(5) == 8);
+    // some more asserts..
+
+    // now let's benchmark:
+    BENCHMARK("Fibonacci 20") {
+        return Fibonacci(20);
+    };
+
+    BENCHMARK("Fibonacci 25") {
+        return Fibonacci(25);
+    };
+
+    BENCHMARK("Fibonacci 30") {
+        return Fibonacci(30);
+    };
+
+    BENCHMARK("Fibonacci 35") {
+        return Fibonacci(35);
+    };
+}
+```
+There's a few things to note:
+- As `BENCHMARK` expands to a lambda expression it is necessary to add a semicolon after
+ the closing brace (as opposed to the first experimental version).
+- The `return` is a handy way to avoid the compiler optimizing away the benchmark code.
+
+Running this already runs the benchmarks and outputs something similar to:
+```

+```
+
+### Advanced benchmarking
+The simplest use case shown above, takes no arguments and just runs the user code that needs to be measured.
+However, if using the `BENCHMARK_ADVANCED` macro and adding a `Catch::Benchmark::Chronometer` argument after
+the macro, some advanced features are available. The contents of the simple benchmarks are invoked once per run,
+while the blocks of the advanced benchmarks are invoked exactly twice:
+once during the estimation phase, and another time during the execution phase.
+
+```c++
+BENCHMARK("simple"){ return long_computation(); };
+
+BENCHMARK_ADVANCED("advanced")(Catch::Benchmark::Chronometer meter) {
+    set_up();
+    meter.measure([] { return long_computation(); });
+};
+```
+
+These advanced benchmarks no longer consist entirely of user code to be measured.
+In these cases, the code to be measured is provided via the
+`Catch::Benchmark::Chronometer::measure` member function. This allows you to set up any
+kind of state that might be required for the benchmark but is not to be included
+in the measurements, like making a vector of random integers to feed to a
+sorting algorithm.
+
+A single call to `Catch::Benchmark::Chronometer::measure` performs the actual measurements
+by invoking the callable object passed in as many times as necessary. Anything
+that needs to be done outside the measurement can be done outside the call to
+`measure`.
+
+The callable object passed in to `measure` can optionally accept an `int`
+parameter.
+
+```c++
+meter.measure([](int i) { return long_computation(i); });
+```
+
+If it accepts an `int` parameter, the sequence number of each run will be passed
+in, starting with 0. This is useful if you want to measure some mutating code,
+for example. The number of runs can be known beforehand by calling
+`Catch::Benchmark::Chronometer::runs`; with this one can set up a different instance to be
+mutated by each run.
+
+```c++
+std::vector<std::string> v(meter.runs());
+std::fill(v.begin(), v.end(), test_string());
+meter.measure([&v](int i) { in_place_escape(v[i]); });
+```
+
+Note that it is not possible to simply use the same instance for different runs
+and resetting it between each run since that would pollute the measurements with
+the resetting code.
+
+It is also possible to just provide an argument name to the simple `BENCHMARK` macro to get
+the same semantics as providing a callable to `meter.measure` with `int` argument:
+
+```c++
+BENCHMARK("indexed", i){ return long_computation(i); };
+```
+
+### Constructors and destructors
+
+All of these tools give you a lot mileage, but there are two things that still
+need special handling: constructors and destructors. The problem is that if you
+use automatic objects they get destroyed by the end of the scope, so you end up
+measuring the time for construction and destruction together. And if you use
+dynamic allocation instead, you end up including the time to allocate memory in
+the measurements.
+
+To solve this conundrum, Catch provides class templates that let you manually
+construct and destroy objects without dynamic allocation and in a way that lets
+you measure construction and destruction separately.
+
+```c++
+BENCHMARK_ADVANCED("construct")(Catch::Benchmark::Chronometer meter) {
+    std::vector<Catch::Benchmark::storage_for<std::string>> storage(meter.runs());
+    meter.measure([&](int i) { storage[i].construct("thing"); });
+};
+
+BENCHMARK_ADVANCED("destroy")(Catch::Benchmark::Chronometer meter) {
+    std::vector<Catch::Benchmark::destructable_object<std::string>> storage(meter.runs());
+    for(auto&& o : storage)
+        o.construct("thing");
+    meter.measure([&](int i) { storage[i].destruct(); });
+};
+```
+
+`Catch::Benchmark::storage_for<T>` objects are just pieces of raw storage suitable for `T`
+objects. You can use the `Catch::Benchmark::storage_for::construct` member function to call a constructor and
+create an object in that storage. So if you want to measure the time it takes
+for a certain constructor to run, you can just measure the time it takes to run
+this function.
+
+When the lifetime of a `Catch::Benchmark::storage_for<T>` object ends, if an actual object was
+constructed there it will be automatically destroyed, so nothing leaks.
+
+If you want to measure a destructor, though, we need to use
+`Catch::Benchmark::destructable_object<T>`. These objects are similar to
+`Catch::Benchmark::storage_for<T>` in that construction of the `T` object is manual, but
+it does not destroy anything automatically. Instead, you are required to call
+the `Catch::Benchmark::destructable_object::destruct` member function, which is what you
+can use to measure the destruction time.
+
+### The optimizer
+
+Sometimes the optimizer will optimize away the very code that you want to
+measure. There are several ways to use results that will prevent the optimiser
+from removing them. You can use the `volatile` keyword, or you can output the
+value to standard output or to a file, both of which force the program to
+actually generate the value somehow.
+
+Catch adds a third option. The values returned by any function provided as user
+code are guaranteed to be evaluated and not optimised out. This means that if
+your user code consists of computing a certain value, you don't need to bother
+with using `volatile` or forcing output. Just `return` it from the function.
+That helps with keeping the code in a natural fashion.
+
+Here's an example:
+
+```c++
+// may measure nothing at all by skipping the long calculation since its
+// result is not used
+BENCHMARK("no return"){ long_calculation(); };
+
+// the result of long_calculation() is guaranteed to be computed somehow
+BENCHMARK("with return"){ return long_calculation(); };
+```
+
+However, there's no other form of control over the optimizer whatsoever. It is
+up to you to write a benchmark that actually measures what you want and doesn't
+just measure the time to do a whole bunch of nothing.
+
+To sum up, there are two simple rules: whatever you would do in handwritten code
+to control optimization still works in Catch; and Catch makes return values
+from user code into observable effects that can't be optimized away.

+# Tooling integration (CI, test runners and so on)
+
+**Contents**<br>
+[Continuous Integration systems](#continuous-integration-systems)<br>
+[Bazel test runner integration](#bazel-test-runner-integration)<br>
+[Low-level tools](#low-level-tools)<br>
+[CMake](#cmake)<br>
+
+This page talks about Catch2's integration with other related tooling,
+like Continuous Integration and 3rd party test runners.
+
+
+## Continuous Integration systems
+
+Probably the most important aspect to using Catch with a build server is the use of different reporters. Catch comes bundled with three reporters that should cover the majority of build servers out there - although adding more for better integration with some is always a possibility (currently we also offer TeamCity, TAP, Automake and SonarQube reporters).
+
+Two of these reporters are built in (XML and JUnit) and the third (TeamCity) is included as a separate header. It's possible that the other two may be split out in the future too - as that would make the core of Catch smaller for those that don't need them.
+
+### XML Reporter
+```-r xml```
+
+The XML Reporter writes in an XML format that is specific to Catch.
+
+The advantage of this format is that it corresponds well to the way Catch works (especially the more unusual features, such as nested sections) and is a fully streaming format - that is it writes output as it goes, without having to store up all its results before it can start writing.
+
+The disadvantage is that, being specific to Catch, no existing build servers understand the format natively. It can be used as input to an XSLT transformation that could convert it to, say, HTML - although this loses the streaming advantage, of course.
+
+### JUnit Reporter
+```-r junit```
+
+The JUnit Reporter writes in an XML format that mimics the JUnit ANT schema.
+
+The advantage of this format is that the JUnit Ant schema is widely understood by most build servers and so can usually be consumed with no additional work.
+
+The disadvantage is that this schema was designed to correspond to how JUnit works - and there is a significant mismatch with how Catch works. Additionally the format is not streamable (because opening elements hold counts of failed and passing tests as attributes) - so the whole test run must complete before it can be written.
+
+
+### TeamCity Reporter
+```-r teamcity```
+
+The TeamCity Reporter writes TeamCity service messages to stdout. In order to be able to use this reporter an additional header must also be included.
+
+Being specific to TeamCity this is the best reporter to use with it - but it is completely unsuitable for any other purpose. It is a streaming format (it writes as it goes) - although test results don't appear in the TeamCity interface until the completion of a suite (usually the whole test run).
+
+### Automake Reporter
+```-r automake```
+
+The Automake Reporter writes out the [meta tags](https://www.gnu.org/software/automake/manual/html_node/Log-files-generation-and-test-results-recording.html#Log-files-generation-and-test-results-recording) expected by automake via `make check`.
+
+### TAP (Test Anything Protocol) Reporter
+```-r tap```
+
+Because of the incremental nature of Catch's test suites and ability to run specific tests, our implementation of TAP reporter writes out the number of tests in a suite last.
+
+### SonarQube Reporter
+```-r sonarqube```
+[SonarQube Generic Test Data](https://docs.sonarqube.org/latest/analysis/generic-test/) XML format for tests metrics.
+
+
+## Bazel test runner integration
+
+Catch2 understands some of the environment variables Bazel uses to control
+test execution. Specifically it understands
+
+ * JUnit output path via `XML_OUTPUT_FILE`
+ * Test filtering via `TESTBRIDGE_TEST_ONLY`
+ * Test sharding via `TEST_SHARD_INDEX`, `TEST_TOTAL_SHARDS`, and `TEST_SHARD_STATUS_FILE`
+
+> Support for `XML_OUTPUT_FILE` was [introduced](https://github.com/catchorg/Catch2/pull/2399) in Catch2 3.0.1
+
+> Support for `TESTBRIDGE_TEST_ONLY` and sharding was introduced in Catch2 3.2.0
+
+This integration is enabled via either a [compile time configuration
+option](configuration.md#bazel-support), or via `BAZEL_TEST` environment
+variable set to "1".
+
+> Support for `BAZEL_TEST` was [introduced](https://github.com/catchorg/Catch2/pull/2459) in Catch2 3.1.0
+
+
+## Low-level tools
+
+### CodeCoverage module (GCOV, LCOV...)
+
+If you are using GCOV tool to get testing coverage of your code, and are not sure how to integrate it with CMake and Catch, there should be an external example over at https://github.com/claremacrae/catch_cmake_coverage
+
+
+### pkg-config
+
+Catch2 provides a rudimentary pkg-config integration, by registering itself
+under the name `catch2`. This means that after Catch2 is installed, you
+can use `pkg-config` to get its include path: `pkg-config --cflags catch2`.
+
+### gdb and lldb scripts
+
+Catch2's `extras` folder also contains two simple debugger scripts,
+`gdbinit` for `gdb` and `lldbinit` for `lldb`. If loaded into their
+respective debugger, these will tell it to step over Catch2's internals
+when stepping through code.
+
+
+## CMake
+
+[As it has been getting kinda long, the documentation of Catch2's
+integration with CMake has been moved to its own page.](cmake-integration.md#top)

+[Installing Catch2 from Bazel](#installing-catch2-from-bazel)<br>
+
+Because we use CMake to build Catch2, we also provide a couple of
+integration points for our users.
+
+1) Catch2 exports a (namespaced) CMake target
+2) Catch2's repository contains CMake scripts for automatic registration
+of `TEST_CASE`s in CTest
+
+## CMake targets
+
+Catch2's CMake build exports two targets, `Catch2::Catch2`, and
+`Catch2::Catch2WithMain`. If you do not need custom `main` function,
+you should be using the latter (and only the latter). Linking against
+it will add the proper include paths and link your target together with
+2 static libraries that implement Catch2 and its main respectively.
+If you need custom `main`, you should link only against `Catch2::Catch2`.
+
+This means that if Catch2 has been installed on the system, it should
+be enough to do
+```cmake
+find_package(Catch2 3 REQUIRED)
+# These tests can use the Catch2-provided main
+add_executable(tests test.cpp)
+target_link_libraries(tests PRIVATE Catch2::Catch2WithMain)
+
+# These tests need their own main
+add_executable(custom-main-tests test.cpp test-main.cpp)
+target_link_libraries(custom-main-tests PRIVATE Catch2::Catch2)
+```
+
+These targets are also provided when Catch2 is used as a subdirectory.
+Assuming Catch2 has been cloned to `lib/Catch2`, you only need to replace
+the `find_package` call with `add_subdirectory(lib/Catch2)` and the snippet
+above still works.
+
+
+Another possibility is to use [FetchContent](https://cmake.org/cmake/help/latest/module/FetchContent.html):
+```cmake
+Include(FetchContent)
+
+FetchContent_Declare(
+  Catch2
+  GIT_REPOSITORY https://github.com/catchorg/Catch2.git
+  GIT_TAG        v3.4.0 # or a later release
+)
+
+FetchContent_MakeAvailable(Catch2)
+
+add_executable(tests test.cpp)
+target_link_libraries(tests PRIVATE Catch2::Catch2WithMain)
+```
+
+
+## Automatic test registration
+
+Catch2's repository also contains three CMake scripts that help users
+with automatically registering their `TEST_CASE`s with CTest. They
+can be found in the `extras` folder, and are
+
+1) `Catch.cmake` (and its dependency `CatchAddTests.cmake`)
+2) `ParseAndAddCatchTests.cmake` (deprecated)
+3) `CatchShardTests.cmake` (and its dependency `CatchShardTestsImpl.cmake`)
+
+If Catch2 has been installed in system, both of these can be used after
+doing `find_package(Catch2 REQUIRED)`. Otherwise you need to add them
+to your CMake module path.
+
+<a id="catch_discover_tests"></a>
+### `Catch.cmake` and `CatchAddTests.cmake`
+
+`Catch.cmake` provides function `catch_discover_tests` to get tests from
+a target. This function works by running the resulting executable with
+`--list-test-names-only` flag, and then parsing the output to find all
+existing tests.
+
+#### Usage
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(tests test.cpp)
+target_link_libraries(tests PRIVATE Catch2::Catch2)
+
+include(CTest)
+include(Catch)
+catch_discover_tests(tests)
+```
+
+When using `FetchContent`, `include(Catch)` will fail unless
+`CMAKE_MODULE_PATH` is explicitly updated to include the extras
+directory.
+
+```cmake
+# ... FetchContent ...
+#
+list(APPEND CMAKE_MODULE_PATH ${catch2_SOURCE_DIR}/extras)
+include(CTest)
+include(Catch)
+catch_discover_tests(tests)
+```
+
+#### Customization
+`catch_discover_tests` can be given several extra arguments:
+```cmake
+catch_discover_tests(target
+                     [TEST_SPEC arg1...]
+                     [EXTRA_ARGS arg1...]
+                     [WORKING_DIRECTORY dir]
+                     [TEST_PREFIX prefix]
+                     [TEST_SUFFIX suffix]
+                     [PROPERTIES name1 value1...]
+                     [TEST_LIST var]
+                     [REPORTER reporter]
+                     [OUTPUT_DIR dir]
+                     [OUTPUT_PREFIX prefix]
+                     [OUTPUT_SUFFIX suffix]
+                     [DISCOVERY_MODE <POST_BUILD|PRE_TEST>]
+)
+```
+
+* `TEST_SPEC arg1...`
+
+Specifies test cases, wildcarded test cases, tags and tag expressions to
+pass to the Catch executable alongside the `--list-test-names-only` flag.
+
+
+* `EXTRA_ARGS arg1...`
+
+Any extra arguments to pass on the command line to each test case.
+
+
+* `WORKING_DIRECTORY dir`
+
+Specifies the directory in which to run the discovered test cases.  If this
+option is not provided, the current binary directory is used.
+
+
+* `TEST_PREFIX prefix`
+
+Specifies a _prefix_ to be added to the name of each discovered test case.
+This can be useful when the same test executable is being used in multiple
+calls to `catch_discover_tests()`, with different `TEST_SPEC` or `EXTRA_ARGS`.
+
+
+* `TEST_SUFFIX suffix`
+
+Same as `TEST_PREFIX`, except it specific the _suffix_ for the test names.
+Both `TEST_PREFIX` and `TEST_SUFFIX` can be specified at the same time.
+
+
+* `PROPERTIES name1 value1...`
+
+Specifies additional properties to be set on all tests discovered by this
+invocation of `catch_discover_tests`.
+
+
+* `TEST_LIST var`
+
+Make the list of tests available in the variable `var`, rather than the
+default `<target>_TESTS`.  This can be useful when the same test
+executable is being used in multiple calls to `catch_discover_tests()`.
+Note that this variable is only available in CTest.
+
+* `REPORTER reporter`
+
+Use the specified reporter when running the test case. The reporter will
+be passed to the test runner as `--reporter reporter`.
+
+* `OUTPUT_DIR dir`
+
+If specified, the parameter is passed along as
+`--out dir/<test_name>` to test executable. The actual file name is the
+same as the test name. This should be used instead of
+`EXTRA_ARGS --out foo` to avoid race conditions writing the result output
+when using parallel test execution.
+
+* `OUTPUT_PREFIX prefix`
+
+May be used in conjunction with `OUTPUT_DIR`.
+If specified, `prefix` is added to each output file name, like so
+`--out dir/prefix<test_name>`.
+
+* `OUTPUT_SUFFIX suffix`
+
+May be used in conjunction with `OUTPUT_DIR`.
+If specified, `suffix` is added to each output file name, like so
+`--out dir/<test_name>suffix`. This can be used to add a file extension to
+the output file name e.g. ".xml".
+
+* `DISCOVERY_MODE mode`
+
+If specified allows control over when test discovery is performed.
+For a value of `POST_BUILD` (default) test discovery is performed at build time.
+For a value of `PRE_TEST` test discovery is delayed until just prior to test
+execution (useful e.g. in cross-compilation environments).
+``DISCOVERY_MODE`` defaults to the value of the
+``CMAKE_CATCH_DISCOVER_TESTS_DISCOVERY_MODE`` variable if it is not passed when
+calling ``catch_discover_tests``. This provides a mechanism for globally
+selecting a preferred test discovery behavior.
+
+### `ParseAndAddCatchTests.cmake`
+
+⚠ This script is [deprecated](https://github.com/catchorg/Catch2/pull/2120)
+in Catch2 2.13.4 and superseded by the above approach using `catch_discover_tests`.
+See [#2092](https://github.com/catchorg/Catch2/issues/2092) for details.
+
+`ParseAndAddCatchTests` works by parsing all implementation files
+associated with the provided target, and registering them via CTest's
+`add_test`. This approach has some limitations, such as the fact that
+commented-out tests will be registered anyway. More serious, only a
+subset of the assertion macros currently available in Catch can be
+detected by this script and tests with any macros that cannot be
+parsed are *silently ignored*.
+
+
+#### Usage
+
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(tests test.cpp)
+target_link_libraries(tests PRIVATE Catch2::Catch2)
+
+include(CTest)
+include(ParseAndAddCatchTests)
+ParseAndAddCatchTests(tests)
+```
+
+
+#### Customization
+
+`ParseAndAddCatchTests` provides some customization points:
+* `PARSE_CATCH_TESTS_VERBOSE` -- When `ON`, the script prints debug
+messages. Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_NO_HIDDEN_TESTS` -- When `ON`, hidden tests (tests
+tagged with either of `[.]` or `[.foo]`) will not be registered.
+Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME` -- When `ON`, adds fixture
+class name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME` -- When `ON`, adds target
+name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS` -- When `ON`, adds test
+file to `CMAKE_CONFIGURE_DEPENDS`. This means that the CMake configuration
+step will be re-ran when the test files change, letting new tests be
+automatically discovered. Defaults to `OFF`.
+
+
+Optionally, one can specify a launching command to run tests by setting the
+variable `OptionalCatchTestLauncher` before calling `ParseAndAddCatchTests`. For
+instance to run some tests using `MPI` and other sequentially, one can write
+```cmake
+set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC})
+ParseAndAddCatchTests(mpi_foo)
+unset(OptionalCatchTestLauncher)
+ParseAndAddCatchTests(bar)
+```
+
+
+### `CatchShardTests.cmake`
+
+> `CatchShardTests.cmake` was introduced in Catch2 3.1.0.
+
+`CatchShardTests.cmake` provides a function
+`catch_add_sharded_tests(TEST_BINARY)` that splits tests from `TEST_BINARY`
+into multiple shards. The tests in each shard and their order is randomized,
+and the seed changes every invocation of CTest.
+
+Currently there are 3 customization points for this script:
+
+ * SHARD_COUNT - number of shards to split target's tests into
+ * REPORTER    - reporter spec to use for tests
+ * TEST_SPEC   - test spec used for filtering tests
+
+Example usage:
+
+```
+include(CatchShardTests)
+
+catch_add_sharded_tests(foo-tests
+  SHARD_COUNT 4
+  REPORTER "xml::out=-"
+  TEST_SPEC "A"
+)
+
+catch_add_sharded_tests(tests
+  SHARD_COUNT 8
+  REPORTER "xml::out=-"
+  TEST_SPEC "B"
+)
+```
+
+This registers total of 12 CTest tests (4 + 8 shards) to run shards
+from `foo-tests` test binary, filtered by a test spec.
+
+_Note that this script is currently a proof-of-concept for reseeding
+shards per CTest run, and thus does not support (nor does it currently
+aim to support) all customization points from
+[`catch_discover_tests`](#catch_discover_tests)._
+
+
+## CMake project options
+
+Catch2's CMake project also provides some options for other projects
+that consume it. These are:
+
+* `BUILD_TESTING` -- When `ON` and the project is not used as a subproject,
+Catch2's test binary will be built. Defaults to `ON`.
+* `CATCH_INSTALL_DOCS` -- When `ON`, Catch2's documentation will be
+included in the installation. Defaults to `ON`.
+* `CATCH_INSTALL_EXTRAS` -- When `ON`, Catch2's extras folder (the CMake
+scripts mentioned above, debugger helpers) will be included in the
+installation. Defaults to `ON`.
+* `CATCH_DEVELOPMENT_BUILD` -- When `ON`, configures the build for development
+of Catch2. This means enabling test projects, warnings and so on.
+Defaults to `OFF`.
+
+
+Enabling `CATCH_DEVELOPMENT_BUILD` also enables further configuration
+customization options:
+
+* `CATCH_BUILD_TESTING` -- When `ON`, Catch2's SelfTest project will be
+built. Defaults to `ON`. Note that Catch2 also obeys `BUILD_TESTING` CMake
+variable, so _both_ of them need to be `ON` for the SelfTest to be built,
+and either of them can be set to `OFF` to disable building SelfTest.
+* `CATCH_BUILD_EXAMPLES` -- When `ON`, Catch2's usage examples will be
+built. Defaults to `OFF`.
+* `CATCH_BUILD_EXTRA_TESTS` -- When `ON`, Catch2's extra tests will be
+built. Defaults to `OFF`.
+* `CATCH_BUILD_FUZZERS` -- When `ON`, Catch2 fuzzing entry points will
+be built. Defaults to `OFF`.
+* `CATCH_ENABLE_WERROR` -- When `ON`, adds `-Werror` or equivalent flag
+to the compilation. Defaults to `ON`.
+* `CATCH_BUILD_SURROGATES` -- When `ON`, each header in Catch2 will be
+compiled separately to ensure that they are self-sufficient.
+Defaults to `OFF`.
+
+
+## `CATCH_CONFIG_*` customization options in CMake
+
+> CMake support for `CATCH_CONFIG_*` options was introduced in Catch2 3.0.1
+
+Due to the new separate compilation model, all the options from the
+[Compile-time configuration docs](configuration.md#top) can also be set
+through Catch2's CMake. To set them, define the option you want as `ON`,
+e.g. `-DCATCH_CONFIG_NOSTDOUT=ON`.
+
+Note that setting the option to `OFF` doesn't disable it. To force disable
+an option, you need to set the `_NO_` form of it to `ON`, e.g.
+`-DCATCH_CONFIG_NO_COLOUR_WIN32=ON`.
+
+
+To summarize the configuration option behaviour with an example:
+
+| `-DCATCH_CONFIG_COLOUR_WIN32` | `-DCATCH_CONFIG_NO_COLOUR_WIN32` |      Result |
+|-------------------------------|----------------------------------|-------------|
+|                          `ON` |                             `ON` |       error |
+|                          `ON` |                            `OFF` |    force-on |
+|                         `OFF` |                             `ON` |   force-off |
+|                         `OFF` |                            `OFF` | auto-detect |

+
+## Installing Catch2 from git repository
+
+If you cannot install Catch2 from a package manager (e.g. Ubuntu 16.04
+provides catch only in version 1.2.0) you might want to install it from
+the repository instead. Assuming you have enough rights, you can just
+install it to the default location, like so:
+```
+$ git clone https://github.com/catchorg/Catch2.git
+$ cd Catch2
+$ cmake -B build -S . -DBUILD_TESTING=OFF
+$ sudo cmake --build build/ --target install
+```
+
+If you do not have superuser rights, you will also need to specify
+[CMAKE_INSTALL_PREFIX](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html)
+when configuring the build, and then modify your calls to
+[find_package](https://cmake.org/cmake/help/latest/command/find_package.html)
+accordingly.
+
+## Installing Catch2 from vcpkg
+
+Alternatively, you can build and install Catch2 using [vcpkg](https://github.com/microsoft/vcpkg/) dependency manager:
+```
+git clone https://github.com/Microsoft/vcpkg.git
+cd vcpkg
+./bootstrap-vcpkg.sh
+./vcpkg integrate install
+./vcpkg install catch2
+```
+
+The catch2 port in vcpkg is kept up to date by microsoft team members and community contributors.
+If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+## Installing Catch2 from Bazel
+
+Catch2 is now a supported module in the Bazel Central Registry. You only need to add one line to your MODULE.bazel file;
+please see https://registry.bazel.build/modules/catch2 for the latest supported version.
+
+You can then add `catch2_main` to each of your C++ test build rules as follows:
+
+```
+cc_test(
+    name = "example_test",
+    srcs = ["example_test.cpp"],
+    deps = [
+        ":example",
+        "@catch2//:catch2_main",
+    ],
+)
+```

+## Specifying which tests to run
+
+<pre>&lt;test-spec> ...</pre>
+
+By providing a test spec, you filter which tests will be run. If you call
+Catch2 without any test spec, then it will run all non-hidden test
+cases. A test case is hidden if it has the `[!benchmark]` tag, any tag
+with a dot at the start, e.g. `[.]` or `[.foo]`.
+
+There are three basic test specs that can then be combined into more
+complex specs:
+
+  * Full test name, e.g. `"Test 1"`.
+
+    This allows only test cases whose name is "Test 1".
+
+  * Wildcarded test name, e.g. `"*Test"`, or `"Test*"`, or `"*Test*"`.
+
+    This allows any test case whose name ends with, starts with, or contains
+    in the middle the string "Test". Note that the wildcard can only be at
+    the start or end.
+
+  * Tag name, e.g. `[some-tag]`.
+
+    This allows any test case tagged with "[some-tag]". Remember that some
+    tags are special, e.g. those that start with "." or with "!".
+
+
+You can also combine the basic test specs to create more complex test
+specs. You can:
+
+  * Concatenate specs to apply all of them, e.g. `[some-tag][other-tag]`.
+
+    This allows test cases that are tagged with **both** "[some-tag]" **and**
+    "[other-tag]". A test case with just "[some-tag]" will not pass the filter,
+    nor will test case with just "[other-tag]".
+
+  * Comma-join specs to apply any of them, e.g. `[some-tag],[other-tag]`.
+
+    This allows test cases that are tagged with **either** "[some-tag]" **or**
+    "[other-tag]". A test case with both will obviously also pass the filter.
+
+    Note that commas take precendence over simple concatenation. This means
+    that `[a][b],[c]` accepts tests that are tagged with either both "[a]" and
+    "[b]", or tests that are tagged with just "[c]".
+
+  * Negate the spec by prepending it with `~`, e.g. `~[some-tag]`.
+
+    This rejects any test case that is tagged with "[some-tag]". Note that
+    rejection takes precedence over other filters.
+
+    Note that negations always binds to the following _basic_ test spec.
+    This means that `~[foo][bar]` negates only the "[foo]" tag and not the
+    "[bar]" tag.
+
+Note that when Catch2 is deciding whether to include a test, first it
+checks whether the test matches any negative filters. If it does,
+the test is rejected. After that, the behaviour depends on whether there
+are positive filters as well. If there are no positive filters, all
+remaining non-hidden tests are included. If there are positive filters,
+only tests that match the positive filters are included.
+
+You can also match test names with special characters by escaping them
+with a backslash (`"\"`), e.g. a test named `"Do A, then B"` is matched
+by `"Do A\, then B"` test spec. Backslash also escapes itself.
+
+
+### Examples
+
+Given these TEST_CASEs,
+```
+TEST_CASE("Test 1") {}
+
+TEST_CASE("Test 2", "[.foo]") {}
+
+TEST_CASE("Test 3", "[.bar]") {}
+
+TEST_CASE("Test 4", "[.][foo][bar]") {}
+```
+
+this is the result of these filters
+```
+./tests                      # Selects only the first test, others are hidden
+./tests "Test 1"             # Selects only the first test, other do not match
+./tests ~"Test 1"            # Selects no tests. Test 1 is rejected, other tests are hidden
+./tests "Test *"             # Selects all tests.
+./tests [bar]                # Selects tests 3 and 4. Other tests are not tagged [bar]
+./tests ~[foo]               # Selects test 1, because it is the only non-hidden test without [foo] tag
+./tests [foo][bar]           # Selects test 4.
+./tests [foo],[bar]          # Selects tests 2, 3, 4.
+./tests ~[foo][bar]          # Selects test 3. 2 and 4 are rejected due to having [foo] tag
+./tests ~"Test 2"[foo]       # Selects test 4, because test 2 is explicitly rejected
+./tests [foo][bar],"Test 1"  # Selects tests 1 and 4.
+./tests "Test 1*"            # Selects test 1, wildcard can match zero characters
+```
+
+_Note: Using plain asterisk on a command line can cause issues with shell
+expansion. Make sure that the asterisk is passed to Catch2 and is not
+interpreted by the shell._
+
+
+<a id="choosing-a-reporter-to-use"></a>
+## Choosing a reporter to use
+
+<pre>-r, --reporter &lt;reporter[::key=value]*&gt;</pre>
+
+Reporters are how the output from Catch2 (results of assertions, tests,
+benchmarks and so on) is formatted and written out. The default reporter
+is called the "Console" reporter and is intended to provide relatively
+verbose and human-friendly output.
+
+Reporters are also individually configurable. To pass configuration options
+to the reporter, you append `::key=value` to the reporter specification
+as many times as you want, e.g. `--reporter xml::out=someFile.xml` or
+`--reporter custom::colour-mode=ansi::Xoption=2`.
+
+The keys must either be prefixed by "X", in which case they are not parsed
+by Catch2 and are only passed down to the reporter, or one of options
+hardcoded into Catch2. Currently there are only 2,
+["out"](#sending-output-to-a-file), and ["colour-mode"](#colour-mode).
+
+_Note that the reporter might still check the X-prefixed options for
+validity, and throw an error if they are wrong._
+
+> Support for passing arguments to reporters through the `-r`, `--reporter` flag was introduced in Catch2 3.0.1
+
+There are multiple built-in reporters, you can see what they do by using the
+[`--list-reporters`](command-line.md#listing-available-tests-tags-or-reporters)
+flag. If you need a reporter providing custom format outside of the already
+provided ones, look at the ["write your own reporter" part of the reporter
+documentation](reporters.md#writing-your-own-reporter).
+
+This option may be passed multiple times to use multiple (different)
+reporters  at the same time. See the [reporter documentation](reporters.md#multiple-reporters)
+for details on what the resulting behaviour is. Also note that at most one
+reporter can be provided without the output-file part of reporter spec.
+This reporter will use the "default" output destination, based on
+the [`-o`, `--out`](#sending-output-to-a-file) option.
+
+> Support for using multiple different reporters at the same time was [introduced](https://github.com/catchorg/Catch2/pull/2183) in Catch2 3.0.1
+
+
+_Note: There is currently no way to escape `::` in the reporter spec,
+and thus the reporter names, or configuration keys and values, cannot
+contain `::`. As `::` in paths is relatively obscure (unlike ':'), we do
+not consider this an issue._
+
+
+<a id="breaking-into-the-debugger"></a>
+## Breaking into the debugger
+<pre>-b, --break</pre>
+
+Under most debuggers Catch2 is capable of automatically breaking on a test
+failure. This allows the user to see the current state of the test during
+failure.
+
+<a id="showing-results-for-successful-tests"></a>
+## Showing results for successful tests
+<pre>-s, --success</pre>
+
+Usually you only want to see reporting for failed tests. Sometimes it's useful to see *all* the output (especially when you don't trust that that test you just added worked first time!).
+To see successful, as well as failing, test results just pass this option. Note that each reporter may treat this option differently. The Junit reporter, for example, logs all results regardless.
+
+<a id="aborting-after-a-certain-number-of-failures"></a>
+## Aborting after a certain number of failures
+<pre>-a, --abort
+-x, --abortx [&lt;failure threshold>]
+</pre>
+
+If a ```REQUIRE``` assertion fails the test case aborts, but subsequent test cases are still run.
+If a ```CHECK``` assertion fails even the current test case is not aborted.
+
+Sometimes this results in a flood of failure messages and you'd rather just see the first few. Specifying ```-a``` or ```--abort``` on its own will abort the whole test run on the first failed assertion of any kind. Use ```-x``` or ```--abortx``` followed by a number to abort after that number of assertion failures.
+
+<a id="listing-available-tests-tags-or-reporters"></a>
+## Listing available tests, tags or reporters
+```
+--list-tests
+--list-tags
+--list-reporters
+--list-listeners
+```
+
+> The `--list*` options became customizable through reporters in Catch2 3.0.1
+
+> The `--list-listeners` option was added in Catch2 3.0.1
+
+`--list-tests` lists all registered tests matching specified test spec.
+Usually this listing also includes tags, and potentially also other
+information, like source location, based on verbosity and reporter's design.
+
+`--list-tags` lists all tags from registered tests matching specified test
+spec. Usually this also includes number of tests cases they match and
+similar information.
+
+`--list-reporters` lists all available reporters and their descriptions.
+
+`--list-listeners` lists all registered listeners and their descriptions.
+
+The [`--verbosity` argument](#output-verbosity) modifies the level of detail provided by the default `--list*` options
+as follows:
+
+| Option             | `normal` (default)              | `quiet`             | `high`                                  |
+|--------------------|---------------------------------|---------------------|-----------------------------------------|
+| `--list-tests`     | Test names and tags             | Test names only     | Same as `normal`, plus source code line |
+| `--list-tags`      | Tags and counts                 | Same as `normal`    | Same as `normal`                        |
+| `--list-reporters` | Reporter names and descriptions | Reporter names only | Same as `normal`                        |
+| `--list-listeners` | Listener names and descriptions | Same as `normal`    | Same as `normal`                        |
+
+<a id="sending-output-to-a-file"></a>
+## Sending output to a file
+<pre>-o, --out &lt;filename&gt;
+</pre>
+
+Use this option to send all output to a file, instead of stdout. You can
+use `-` as the filename to explicitly send the output to stdout (this is
+useful e.g. when using multiple reporters).
+
+> Support for `-` as the filename was introduced in Catch2 3.0.1
+
+Filenames starting with "%" (percent symbol) are reserved by Catch2 for
+meta purposes, e.g. using `%debug` as the filename opens stream that
+writes to platform specific debugging/logging mechanism.
+
+Catch2 currently recognizes 3 meta streams:
+
+* `%debug` - writes to platform specific debugging/logging output
+* `%stdout` - writes to stdout
+* `%stderr` - writes to stderr
+
+> Support for `%stdout` and `%stderr` was introduced in Catch2 3.0.1
+
+
+<a id="naming-a-test-run"></a>
+## Naming a test run
+<pre>-n, --name &lt;name for test run></pre>
+
+If a name is supplied it will be used by the reporter to provide an overall name for the test run. This can be useful if you are sending to a file, for example, and need to distinguish different test runs - either from different Catch executables or runs of the same executable with different options. If not supplied the name is defaulted to the name of the executable.
+
+<a id="eliding-assertions-expected-to-throw"></a>
+## Eliding assertions expected to throw
+<pre>-e, --nothrow</pre>
+
+Skips all assertions that test that an exception is thrown, e.g. ```REQUIRE_THROWS```.
+
+These can be a nuisance in certain debugging environments that may break when exceptions are thrown (while this is usually optional for handled exceptions, it can be useful to have enabled if you are trying to track down something unexpected).
+
+Sometimes exceptions are expected outside of one of the assertions that tests for them (perhaps thrown and caught within the code-under-test). The whole test case can be skipped when using ```-e``` by marking it with the ```[!throws]``` tag.
+
+When running with this option any throw checking assertions are skipped so as not to contribute additional noise. Be careful if this affects the behaviour of subsequent tests.
+
+<a id="invisibles"></a>
+## Make whitespace visible
+<pre>-i, --invisibles</pre>
+
+If a string comparison fails due to differences in whitespace - especially leading or trailing whitespace - it can be hard to see what's going on.
+This option transforms tabs and newline characters into ```\t``` and ```\n``` respectively when printing.
+
+<a id="warnings"></a>
+## Warnings
+<pre>-w, --warn &lt;warning name></pre>
+
+You can think of Catch2's warnings as the equivalent of `-Werror` (`/WX`)
+flag for C++ compilers. It turns some suspicious occurrences, like a section
+without assertions, into errors. Because these might be intended, warnings
+are not enabled by default, but user can opt in.
+
+You can enable multiple warnings at the same time.
+
+There are currently two warnings implemented:
+
+```
+    NoAssertions        // Fail test case / leaf section if no assertions
+                        // (e.g. `REQUIRE`) is encountered.
+    UnmatchedTestSpec   // Fail test run if any of the CLI test specs did
+                        // not match any tests.
+```
+
+> `UnmatchedTestSpec` was introduced in Catch2 3.0.1.
+
+
+<a id="reporting-timings"></a>
+## Reporting timings
+<pre>-d, --durations &lt;yes/no></pre>
+
+When set to ```yes``` Catch will report the duration of each test case, in seconds with millisecond precision. Note that it does this regardless of whether a test case passes or fails. Note, also, the certain reporters (e.g. Junit) always report test case durations regardless of this option being set or not.
+
+<pre>-D, --min-duration &lt;value></pre>
+
+> `--min-duration` was [introduced](https://github.com/catchorg/Catch2/pull/1910) in Catch2 2.13.0
+
+When set, Catch will report the duration of each test case that took more
+than &lt;value> seconds, in seconds with millisecond precision. This option is overridden by both
+`-d yes` and `-d no`, so that either all durations are reported, or none
+are.
+
+
+<a id="input-file"></a>
+## Load test names to run from a file
+<pre>-f, --input-file &lt;filename></pre>
+
+Provide the name of a file that contains a list of test case names,
+one per line. Blank lines are skipped.
+
+A useful way to generate an initial instance of this file is to combine
+the [`--list-tests`](#listing-available-tests-tags-or-reporters) flag with
+the [`--verbosity quiet`](#output-verbosity) option. You can also
+use test specs to filter this list down to what you want first.
+
+
+<a id="order"></a>
+## Specify the order test cases are run
+<pre>--order &lt;decl|lex|rand&gt;</pre>
+
+Test cases are ordered one of three ways:
+
+### decl
+Declaration order (this is the default order if no --order argument is provided).
+Tests in the same translation unit are sorted using their declaration orders,
+different TUs are sorted in an implementation (linking) dependent order.
+
+
+### lex
+Lexicographic order. Tests are sorted by their name, their tags are ignored.
+
+
+### rand
+
+Randomly ordered. The order is dependent on Catch2's random seed (see
+[`--rng-seed`](#rng-seed)), and is subset invariant. What this means
+is that as long as the random seed is fixed, running only some tests
+(e.g. via tag) does not change their relative order.
+
+> The subset stability was introduced in Catch2 v2.12.0
+
+Since the random order was made subset stable, we promise that given
+the same random seed, the order of test cases will be the same across
+different platforms, as long as the tests were compiled against identical
+version of Catch2. We reserve the right to change the relative order
+of tests cases between Catch2 versions, but it is unlikely to happen often.
+
+
+<a id="rng-seed"></a>
+## Specify a seed for the Random Number Generator
+<pre>--rng-seed &lt;'time'|'random-device'|number&gt;</pre>
+
+Sets the seed for random number generators used by Catch2. These are used
+e.g. to shuffle tests when user asks for tests to be in random order.
+
+Using `time` as the argument asks Catch2 generate the seed through call
+to `std::time(nullptr)`. This provides very weak randomness and multiple
+runs of the binary can generate the same seed if they are started close
+to each other.
+
+Using `random-device` asks for `std::random_device` to be used instead.
+If your implementation provides working `std::random_device`, it should
+be preferred to using `time`. Catch2 uses `std::random_device` by default.

+
+<a id="wait-for-keypress"></a>
+## Wait for key before continuing
+<pre>--wait-for-keypress &lt;never|start|exit|both&gt;</pre>
+

+either before running any tests, after running all tests - or both, depending on the argument.
+
+<a id="skip-benchmarks"></a>
+## Skip all benchmarks
+<pre>--skip-benchmarks</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/2408) in Catch2 3.0.1.
+
+This flag tells Catch2 to skip running all benchmarks. Benchmarks in this
+case mean code blocks in `BENCHMARK` and `BENCHMARK_ADVANCED` macros, not
+test cases with the `[!benchmark]` tag.
+
+<a id="benchmark-samples"></a>
+## Specify the number of benchmark samples to collect
+<pre>--benchmark-samples &lt;# of samples&gt;</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+When running benchmarks a number of "samples" is collected. This is the base data for later statistical analysis.
+Per sample a clock resolution dependent number of iterations of the user code is run, which is independent of the number of samples. Defaults to 100.
+
+<a id="benchmark-resamples"></a>
+## Specify the number of resamples for bootstrapping
+<pre>--benchmark-resamples &lt;# of resamples&gt;</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+After the measurements are performed, statistical [bootstrapping] is performed
+on the samples. The number of resamples for that bootstrapping is configurable
+but defaults to 100000. Due to the bootstrapping it is possible to give
+estimates for the mean and standard deviation. The estimates come with a lower
+bound and an upper bound, and the confidence interval (which is configurable but
+defaults to 95%).
+
+ [bootstrapping]: http://en.wikipedia.org/wiki/Bootstrapping_%28statistics%29
+
+<a id="benchmark-confidence-interval"></a>
+## Specify the confidence-interval for bootstrapping
+<pre>--benchmark-confidence-interval &lt;confidence-interval&gt;</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+The confidence-interval is used for statistical bootstrapping on the samples to
+calculate the upper and lower bounds of mean and standard deviation.
+Must be between 0 and 1 and defaults to 0.95.
+
+<a id="benchmark-no-analysis"></a>
+## Disable statistical analysis of collected benchmark samples
+<pre>--benchmark-no-analysis</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+When this flag is specified no bootstrapping or any other statistical analysis is performed.
+Instead the user code is only measured and the plain mean from the samples is reported.
+
+<a id="benchmark-warmup-time"></a>
+## Specify the amount of time in milliseconds spent on warming up each test
+<pre>--benchmark-warmup-time</pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/1844) in Catch2 2.11.2.
+
+Configure the amount of time spent warming up each test.
+
+<a id="usage"></a>
+## Usage
+<pre>-h, -?, --help</pre>
+
+Prints the command line arguments to stdout
+
+
+<a id="run-section"></a>
+## Specify the section to run
+<pre>-c, --section &lt;section name&gt;</pre>
+
+To limit execution to a specific section within a test case, use this option one or more times.
+To narrow to sub-sections use multiple instances, where each subsequent instance specifies a deeper nesting level.
+
+E.g. if you have:
+
+<pre>
+TEST_CASE( "Test" ) {
+  SECTION( "sa" ) {
+    SECTION( "sb" ) {
+      /*...*/
+    }
+    SECTION( "sc" ) {
+      /*...*/
+    }
+  }
+  SECTION( "sd" ) {
+    /*...*/
+  }
+}
+</pre>
+
+Then you can run `sb` with:
+<pre>./MyExe Test -c sa -c sb</pre>
+
+Or run just `sd` with:
+<pre>./MyExe Test -c sd</pre>
+
+To run all of `sa`, including `sb` and `sc` use:
+<pre>./MyExe Test -c sa</pre>
+
+There are some limitations of this feature to be aware of:
+- Code outside of sections being skipped will still be executed - e.g. any set-up code in the TEST_CASE before the
+start of the first section.</br>
+- At time of writing, wildcards are not supported in section names.
+- If you specify a section without narrowing to a test case first then all test cases will be executed
+(but only matching sections within them).
+
+
+<a id="filenames-as-tags"></a>
+## Filenames as tags
+<pre>-#, --filenames-as-tags</pre>
+
+This option adds an extra tag to all test cases. The tag is `#` followed
+by the unqualified filename the test case is defined in, with the _last_
+extension stripped out.
+
+For example, tests within the file `tests\SelfTest\UsageTests\BDD.tests.cpp`
+will be given the `[#BDD.tests]` tag.
+
+
+<a id="colour-mode"></a>
+## Override output colouring
+<pre>--colour-mode &lt;ansi|win32|none|default&gt;</pre>
+
+> The `--colour-mode` option replaced the old `--colour` option in Catch2 3.0.1
+
+
+Catch2 support two different ways of colouring terminal output, and by
+default it attempts to make a good guess on which implementation to use
+(and whether to even use it, e.g. Catch2 tries to avoid writing colour
+codes when writing the results into a file).
+
+`--colour-mode` allows the user to explicitly select what happens.
+
+* `--colour-mode ansi` tells Catch2 to always use ANSI colour codes, even
+when writing to a file
+* `--colour-mode win32` tells Catch2 to use colour implementation based
+  on Win32 terminal API
+* `--colour-mode none` tells Catch2 to disable colours completely
+* `--colour-mode default` lets Catch2 decide
+
+`--colour-mode default` is the default setting.
+
+
+<a id="test-sharding"></a>
+## Test Sharding
+<pre>--shard-count <#number of shards>, --shard-index <#shard index to run></pre>
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/2257) in Catch2 3.0.1.
+
+When `--shard-count <#number of shards>` is used, the tests to execute
+will be split evenly in to the given number of sets, identified by indices
+starting at 0. The tests in the set given by
+`--shard-index <#shard index to run>` will be executed. The default shard
+count is `1`, and the default index to run is `0`.
+
+_Shard index must be less than number of shards. As the name suggests,
+it is treated as an index of the shard to run._
+
+Sharding is useful when you want to split test execution across multiple
+processes, as is done with the [Bazel test sharding](https://docs.bazel.build/versions/main/test-encyclopedia.html#test-sharding).
+
+
+<a id="no-tests-override"></a>
+## Allow running the binary without tests
+<pre>--allow-running-no-tests</pre>
+
+> Introduced in Catch2 3.0.1.
+
+By default, Catch2 test binaries return non-0 exit code if no tests were run,
+e.g. if the binary was compiled with no tests, the provided test spec matched no
+tests, or all tests [were skipped at runtime](skipping-passing-failing.md#top). This flag
+overrides that, so a test run with no tests still returns 0.
+
+## Output verbosity
+```
+-v, --verbosity <quiet|normal|high>
+```
+
+Changing verbosity might change how many details Catch2's reporters output.
+However, you should consider changing the verbosity level as a _suggestion_.
+Not all reporters support all verbosity levels, e.g. because the reporter's
+format cannot meaningfully change. In that case, the verbosity level is
+ignored.
+
+Verbosity defaults to _normal_.

+# Comparing floating point numbers with Catch2
+
+If you are not deeply familiar with them, floating point numbers can be
+unintuitive. This also applies to comparing floating point numbers for
+(in)equality.
+
+This page assumes that you have some understanding of both FP, and the
+meaning of different kinds of comparisons, and only goes over what
+functionality Catch2 provides to help you with comparing floating point
+numbers. If you do not have this understanding, we recommend that you first
+study up on floating point numbers and their comparisons, e.g. by [reading
+this blog post](https://codingnest.com/the-little-things-comparing-floating-point-numbers/).
+
+
+## Floating point matchers
+
+```
+#include <catch2/matchers/catch_matchers_floating_point.hpp>
+```
+
+[Matchers](matchers.md#top) are the preferred way of comparing floating
+point numbers in Catch2. We provide 3 of them:
+
+* `WithinAbs(double target, double margin)`,
+* `WithinRel(FloatingPoint target, FloatingPoint eps)`, and
+* `WithinULP(FloatingPoint target, uint64_t maxUlpDiff)`.
+
+> `WithinRel` matcher was introduced in Catch2 2.10.0
+
+As with all matchers, you can combine multiple floating point matchers
+in a single assertion. For example, to check that some computation matches
+a known good value within 0.1% or is close enough (no different to 5
+decimal places) to zero, we would write this assertion:
+
+```cpp
+    REQUIRE_THAT( computation(input),
+        Catch::Matchers::WithinRel(expected, 0.001)
+     || Catch::Matchers::WithinAbs(0, 0.000001) );
+```
+
+
+### WithinAbs
+
+`WithinAbs` creates a matcher that accepts floating point numbers whose
+difference with `target` is less-or-equal to the `margin`. Since `float`
+can be converted to `double` without losing precision, only `double`
+overload exists.
+
+```cpp
+REQUIRE_THAT(1.0, WithinAbs(1.2, 0.2));
+REQUIRE_THAT(0.f, !WithinAbs(1.0, 0.5));
+// Notice that infinity == infinity for WithinAbs
+REQUIRE_THAT(INFINITY, WithinAbs(INFINITY, 0));
+```
+
+
+### WithinRel
+
+`WithinRel` creates a matcher that accepts floating point numbers that
+are _approximately equal_ to the `target` with a tolerance of `eps.`
+Specifically, it matches if
+`|arg - target| <= eps * max(|arg|, |target|)` holds. If you do not
+specify `eps`, `std::numeric_limits<FloatingPoint>::epsilon * 100`
+is used as the default.
+
+```cpp
+// Notice that WithinRel comparison is symmetric, unlike Approx's.
+REQUIRE_THAT(1.0, WithinRel(1.1, 0.1));
+REQUIRE_THAT(1.1, WithinRel(1.0, 0.1));
+// Notice that inifnity == infinity for WithinRel
+REQUIRE_THAT(INFINITY, WithinRel(INFINITY));
+```
+
+
+### WithinULP
+
+`WithinULP` creates a matcher that accepts floating point numbers that
+are no more than `maxUlpDiff`
+[ULPs](https://en.wikipedia.org/wiki/Unit_in_the_last_place)
+away from the `target` value. The short version of what this means
+is that there is no more than `maxUlpDiff - 1` representable floating
+point numbers between the argument for matching and the `target` value.
+
+When using the ULP matcher in Catch2, it is important to keep in mind
+that Catch2 interprets ULP distance slightly differently than
+e.g. `std::nextafter` does.
+
+Catch2's ULP calculation obeys these relations:
+  * `ulpDistance(-x, x) == 2 * ulpDistance(x, 0)`
+  * `ulpDistance(-0, 0) == 0` (due to the above)
+  * `ulpDistance(DBL_MAX, INFINITY) == 1`
+  * `ulpDistancE(NaN, x) == infinity`
+
+
+**Important**: The WithinULP matcher requires the platform to use the
+[IEEE-754](https://en.wikipedia.org/wiki/IEEE_754) representation for
+floating point numbers.
+
+```cpp
+REQUIRE_THAT( -0.f, WithinULP( 0.f, 0 ) );
+```
+
+
+## `Approx`
+
+```
+#include <catch2/catch_approx.hpp>
+```
+
+**We strongly recommend against using `Approx` when writing new code.**
+You should be using floating point matchers instead.
+
+Catch2 provides one more way to handle floating point comparisons. It is
+`Approx`, a special type with overloaded comparison operators, that can
+be used in standard assertions, e.g.
+
+```cpp
+REQUIRE(0.99999 == Catch::Approx(1));
+```
+
+`Approx` supports four comparison operators, `==`, `!=`, `<=`, `>=`, and can
+also be used with strong typedefs over `double`s. It can be used for both
+relative and margin comparisons by using its three customization points.
+Note that the semantics of this is always that of an _or_, so if either
+the relative or absolute margin comparison passes, then the whole comparison
+passes.
+
+The downside to `Approx` is that it has a couple of issues that we cannot
+fix without breaking backwards compatibility. Because Catch2 also provides
+complete set of matchers that implement different floating point comparison
+methods, `Approx` is left as-is, is considered deprecated, and should
+not be used in new code.
+
+The issues are
+  * All internal computation is done in `double`s, leading to slightly
+    different results if the inputs were floats.
+  * `Approx`'s relative margin comparison is not symmetric. This means
+    that `Approx( 10 ).epsilon(0.1) != 11.1` but `Approx( 11.1 ).epsilon(0.1) == 10`.
+  * By default, `Approx` only uses relative margin comparison. This means
+    that `Approx(0) == X` only passes for `X == 0`.
+
+
+### Approx details
+
+If you still want/need to know more about `Approx`, read on.
+
+Catch2 provides a UDL for `Approx`; `_a`. It resides in the `Catch::literals`
+namespace, and can be used like this:
+
+```cpp
+using namespace Catch::literals;
+REQUIRE( performComputation() == 2.1_a );
+```
+
+`Approx` has three customization points for the comparison:
+
+* **epsilon** - epsilon sets the coefficient by which a result
+can differ from `Approx`'s value before it is rejected.
+_Defaults to `std::numeric_limits<float>::epsilon()*100`._
+
+```cpp
+Approx target = Approx(100).epsilon(0.01);
+100.0 == target; // Obviously true
+200.0 == target; // Obviously still false
+100.5 == target; // True, because we set target to allow up to 1% difference
+```
+
+
+* **margin** - margin sets the absolute value by which
+a result can differ from `Approx`'s value before it is rejected.
+_Defaults to `0.0`._
+
+```cpp
+Approx target = Approx(100).margin(5);
+100.0 == target; // Obviously true
+200.0 == target; // Obviously still false
+104.0 == target; // True, because we set target to allow absolute difference of at most 5
+```
+
+* **scale** - scale is used to change the magnitude of `Approx` for the relative check.
+_By default, set to `0.0`._
+
+Scale could be useful if the computation leading to the result worked
+on a different scale than is used by the results. Approx's scale is added
+to Approx's value when computing the allowed relative margin from the
+Approx's value.

+
+Catch2 is designed to "just work" as much as possible, and most of the
+configuration options below are changed automatically during compilation,
+according to the detected environment. However, this detection can also
+be overridden by users, using macros documented below, and/or CMake options
+with the same name.
+
+
+## Prefixing Catch macros
+
+    CATCH_CONFIG_PREFIX_ALL       // Prefix all macros with CATCH_
+    CATCH_CONFIG_PREFIX_MESSAGES  // Prefix only INFO, UNSCOPED_INFO, WARN and CAPTURE
+
+To keep test code clean and uncluttered Catch uses short macro names (e.g. ```TEST_CASE``` and ```REQUIRE```). Occasionally these may conflict with identifiers from platform headers or the system under test. In this case the above identifier can be defined. This will cause all the Catch user macros to be prefixed with ```CATCH_``` (e.g. ```CATCH_TEST_CASE``` and ```CATCH_REQUIRE```).
+
+
+## Terminal colour
+
+    CATCH_CONFIG_COLOUR_WIN32     // Force enables compiling colouring impl based on Win32 console API
+    CATCH_CONFIG_NO_COLOUR_WIN32  // Force disables ...
+
+Yes, Catch2 uses the british spelling of colour.
+
+Catch2 attempts to autodetect whether the Win32 console colouring API,
+`SetConsoleTextAttribute`, is available, and if it is available it compiles
+in a console colouring implementation that uses it.
+
+This option can be used to override Catch2's autodetection and force the
+compilation either ON or OFF.
+
+
+## Console width
+
+    CATCH_CONFIG_CONSOLE_WIDTH = x // where x is a number
+
+Catch formats output intended for the console to fit within a fixed number of characters. This is especially important as indentation is used extensively and uncontrolled line wraps break this.
+By default a console width of 80 is assumed but this can be controlled by defining the above identifier to be a different value.
+
+## stdout
+
+    CATCH_CONFIG_NOSTDOUT
+
+To support platforms that do not provide `std::cout`, `std::cerr` and
+`std::clog`, Catch does not use them directly, but rather calls
+`Catch::cout`, `Catch::cerr` and `Catch::clog`. You can replace their
+implementation by defining `CATCH_CONFIG_NOSTDOUT` and implementing
+them yourself, their signatures are:
+
+    std::ostream& cout();
+    std::ostream& cerr();
+    std::ostream& clog();
+
+[You can see an example of replacing these functions here.](
+../examples/231-Cfg-OutputStreams.cpp)
+
+
+## Fallback stringifier
+
+By default, when Catch's stringification machinery has to stringify
+a type that does not specialize `StringMaker`, does not overload `operator<<`,
+is not an enumeration and is not a range, it uses `"{?}"`. This can be
+overridden by defining `CATCH_CONFIG_FALLBACK_STRINGIFIER` to name of a
+function that should perform the stringification instead.
+
+All types that do not provide `StringMaker` specialization or `operator<<`
+overload will be sent to this function (this includes enums and ranges).
+The provided function must return `std::string` and must accept any type,
+e.g. via overloading.
+
+_Note that if the provided function does not handle a type and this type
+requires to be stringified, the compilation will fail._
+
+
+## Default reporter
+
+Catch's default reporter can be changed by defining macro
+`CATCH_CONFIG_DEFAULT_REPORTER` to string literal naming the desired
+default reporter.
+
+This means that defining `CATCH_CONFIG_DEFAULT_REPORTER` to `"console"`
+is equivalent with the out-of-the-box experience.
+
+
+## Bazel support
+
+Compiling Catch2 with `CATCH_CONFIG_BAZEL_SUPPORT` force-enables Catch2's
+support for Bazel's environment variables (normally Catch2 looks for
+`BAZEL_TEST=1` env var first).
+
+This can be useful if you are using older versions of Bazel, that do not
+yet have `BAZEL_TEST` env var support.
+
+> `CATCH_CONFIG_BAZEL_SUPPORT` was [introduced](https://github.com/catchorg/Catch2/pull/2399) in Catch2 3.0.1.
+
+> `CATCH_CONFIG_BAZEL_SUPPORT` was [deprecated](https://github.com/catchorg/Catch2/pull/2459) in Catch2 3.1.0.
+
+
+## C++11 toggles
+
+    CATCH_CONFIG_CPP11_TO_STRING // Use `std::to_string`
+
+Because we support platforms whose standard library does not contain
+`std::to_string`, it is possible to force Catch to use a workaround
+based on `std::stringstream`. On platforms other than Android,
+the default is to use `std::to_string`. On Android, the default is to
+use the `stringstream` workaround. As always, it is possible to override
+Catch's selection, by defining either `CATCH_CONFIG_CPP11_TO_STRING` or
+`CATCH_CONFIG_NO_CPP11_TO_STRING`.
+
+
+## C++17 toggles
+
+    CATCH_CONFIG_CPP17_UNCAUGHT_EXCEPTIONS  // Override std::uncaught_exceptions (instead of std::uncaught_exception) support detection
+    CATCH_CONFIG_CPP17_STRING_VIEW          // Override std::string_view support detection (Catch provides a StringMaker specialization by default)
+    CATCH_CONFIG_CPP17_VARIANT              // Override std::variant support detection (checked by CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER)
+    CATCH_CONFIG_CPP17_OPTIONAL             // Override std::optional support detection (checked by CATCH_CONFIG_ENABLE_OPTIONAL_STRINGMAKER)
+    CATCH_CONFIG_CPP17_BYTE                 // Override std::byte support detection (Catch provides a StringMaker specialization by default)
+
+> `CATCH_CONFIG_CPP17_STRING_VIEW` was [introduced](https://github.com/catchorg/Catch2/issues/1376) in Catch2 2.4.1.
+
+Catch contains basic compiler/standard detection and attempts to use
+some C++17 features whenever appropriate. This automatic detection
+can be manually overridden in both directions, that is, a feature
+can be enabled by defining the macro in the table above, and disabled
+by using `_NO_` in the macro, e.g. `CATCH_CONFIG_NO_CPP17_UNCAUGHT_EXCEPTIONS`.
+
+
+## Other toggles
+
+    CATCH_CONFIG_COUNTER                    // Use __COUNTER__ to generate unique names for test cases
+    CATCH_CONFIG_WINDOWS_SEH                // Enable SEH handling on Windows
+    CATCH_CONFIG_FAST_COMPILE               // Sacrifices some (rather minor) features for compilation speed
+    CATCH_CONFIG_POSIX_SIGNALS              // Enable handling POSIX signals
+    CATCH_CONFIG_WINDOWS_CRTDBG             // Enable leak checking using Windows's CRT Debug Heap
+    CATCH_CONFIG_DISABLE_STRINGIFICATION    // Disable stringifying the original expression
+    CATCH_CONFIG_DISABLE                    // Disables assertions and test case registration
+    CATCH_CONFIG_WCHAR                      // Enables use of wchart_t
+    CATCH_CONFIG_EXPERIMENTAL_REDIRECT      // Enables the new (experimental) way of capturing stdout/stderr
+    CATCH_CONFIG_USE_ASYNC                  // Force parallel statistical processing of samples during benchmarking
+    CATCH_CONFIG_ANDROID_LOGWRITE           // Use android's logging system for debug output
+    CATCH_CONFIG_GLOBAL_NEXTAFTER           // Use nextafter{,f,l} instead of std::nextafter
+    CATCH_CONFIG_GETENV                     // System has a working `getenv`
+
+> [`CATCH_CONFIG_ANDROID_LOGWRITE`](https://github.com/catchorg/Catch2/issues/1743) and [`CATCH_CONFIG_GLOBAL_NEXTAFTER`](https://github.com/catchorg/Catch2/pull/1739) were introduced in Catch2 2.10.0
+
+> `CATCH_CONFIG_GETENV` was [introduced](https://github.com/catchorg/Catch2/pull/2562) in Catch2 3.2.0
+
+Currently Catch enables `CATCH_CONFIG_WINDOWS_SEH` only when compiled with MSVC, because some versions of MinGW do not have the necessary Win32 API support.
+
+`CATCH_CONFIG_POSIX_SIGNALS` is on by default, except when Catch is compiled under `Cygwin`, where it is disabled by default (but can be force-enabled by defining `CATCH_CONFIG_POSIX_SIGNALS`).
+
+`CATCH_CONFIG_GETENV` is on by default, except when Catch2 is compiled for
+platforms that lacks working `std::getenv` (currently Windows UWP and
+Playstation).
+
+`CATCH_CONFIG_WINDOWS_CRTDBG` is off by default. If enabled, Windows's
+CRT is used to check for memory leaks, and displays them after the tests
+finish running. This option only works when linking against the default
+main, and must be defined for the whole library build.
+
+`CATCH_CONFIG_WCHAR` is on by default, but can be disabled. Currently
+it is only used in support for DJGPP cross-compiler.
+
+With the exception of `CATCH_CONFIG_EXPERIMENTAL_REDIRECT`,
+these toggles can be disabled by using `_NO_` form of the toggle,
+e.g. `CATCH_CONFIG_NO_WINDOWS_SEH`.
+
+### `CATCH_CONFIG_FAST_COMPILE`
+This compile-time flag speeds up compilation of assertion macros by ~20%,
+by disabling the generation of assertion-local try-catch blocks for
+non-exception family of assertion macros ({`REQUIRE`,`CHECK`}{``,`_FALSE`, `_THAT`}).
+This disables translation of exceptions thrown under these assertions, but
+should not lead to false negatives.
+
+`CATCH_CONFIG_FAST_COMPILE` has to be either defined, or not defined,
+in all translation units that are linked into single test binary.
+
+### `CATCH_CONFIG_DISABLE_STRINGIFICATION`
+This toggle enables a workaround for VS 2017 bug. For details see [known limitations](limitations.md#visual-studio-2017----raw-string-literal-in-assert-fails-to-compile).
+
+### `CATCH_CONFIG_DISABLE`
+This toggle removes most of Catch from given file. This means that `TEST_CASE`s are not registered and assertions are turned into no-ops. Useful for keeping tests within implementation files (ie for functions with internal linkage), instead of in external files.
+
+This feature is considered experimental and might change at any point.
+
+_Inspired by Doctest's `DOCTEST_CONFIG_DISABLE`_
+
+
+## Enabling stringification
+
+By default, Catch does not stringify some types from the standard library. This is done to avoid dragging in various standard library headers by default. However, Catch does contain these and can be configured to provide them, using these macros:
+
+    CATCH_CONFIG_ENABLE_PAIR_STRINGMAKER     // Provide StringMaker specialization for std::pair
+    CATCH_CONFIG_ENABLE_TUPLE_STRINGMAKER    // Provide StringMaker specialization for std::tuple
+    CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER  // Provide StringMaker specialization for std::variant, std::monostate (on C++17)
+    CATCH_CONFIG_ENABLE_OPTIONAL_STRINGMAKER // Provide StringMaker specialization for std::optional (on C++17)
+    CATCH_CONFIG_ENABLE_ALL_STRINGMAKERS     // Defines all of the above
+
+> `CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER` was [introduced](https://github.com/catchorg/Catch2/issues/1380) in Catch2 2.4.1.
+
+> `CATCH_CONFIG_ENABLE_OPTIONAL_STRINGMAKER` was [introduced](https://github.com/catchorg/Catch2/issues/1510) in Catch2 2.6.0.
+
+## Disabling exceptions
+
+> Introduced in Catch2 2.4.0.
+
+By default, Catch2 uses exceptions to signal errors and to abort tests
+when an assertion from the `REQUIRE` family of assertions fails. We also
+provide an experimental support for disabling exceptions. Catch2 should
+automatically detect when it is compiled with exceptions disabled, but
+it can be forced to compile without exceptions by defining
+
+    CATCH_CONFIG_DISABLE_EXCEPTIONS
+
+Note that when using Catch2 without exceptions, there are 2 major
+limitations:
+
+1) If there is an error that would normally be signalled by an exception,
+the exception's message will instead be written to `Catch::cerr` and
+`std::terminate` will be called.
+2) If an assertion from the `REQUIRE` family of macros fails,
+`std::terminate` will be called after the active reporter returns.
+
+
+There is also a customization point for the exact behaviour of what
+happens instead of exception being thrown. To use it, define
+
+    CATCH_CONFIG_DISABLE_EXCEPTIONS_CUSTOM_HANDLER
+
+and provide a definition for this function:
+
+```cpp
+namespace Catch {
+    [[noreturn]]
+    void throw_exception(std::exception const&);
+}
+```
+
+## Overriding Catch's debug break (`-b`)
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/1846) in Catch2 2.11.2.
+
+You can override Catch2's break-into-debugger code by defining the
+`CATCH_BREAK_INTO_DEBUGGER()` macro. This can be used if e.g. Catch2 does
+not know your platform, or your platform is misdetected.
+
+The macro will be used as is, that is, `CATCH_BREAK_INTO_DEBUGGER();`
+must compile and must break into debugger.
+
+
+## Static analysis support
+
+> Introduced in Catch2 3.4.0.
+
+Some parts of Catch2, e.g. `SECTION`s, can be hard for static analysis
+tools to reason about. Catch2 can change its internals to help static
+analysis tools reason about the tests.
+
+Catch2 automatically detects some static analysis tools (initial
+implementation checks for clang-tidy and Coverity), but you can override
+its detection (in either direction) via
+
+```
+CATCH_CONFIG_EXPERIMENTAL_STATIC_ANALYSIS_SUPPORT     // force enables static analysis help
+CATCH_CONFIG_NO_EXPERIMENTAL_STATIC_ANALYSIS_SUPPORT  // force disables static analysis help
+```
+
+_As the name suggests, this is currently experimental, and thus we provide
+no backwards compatibility guarantees._
+
+**DO NOT ENABLE THIS FOR BUILDS YOU INTEND TO RUN.** The changed internals
+are not meant to be runnable, only "scannable".

+
+So you want to contribute something to Catch2? That's great! Whether it's
+a bug fix, a new feature, support for additional compilers - or just
+a fix to the documentation - all contributions are very welcome and very
+much appreciated. Of course so are bug reports, other comments, and
+questions, but generally it is a better idea to ask questions in our
+[Discord](https://discord.gg/4CWS9zD), than in the issue tracker.
+
+
+This page covers some guidelines and helpful tips for contributing
+to the codebase itself.
+
+## Using Git(Hub)
+
+Ongoing development happens in the `devel` branch for Catch2 v3, and in
+`v2.x` for maintenance updates to the v2 versions.
+
+Commits should be small and atomic. A commit is atomic when, after it is
+applied, the codebase, tests and all, still works as expected. Small
+commits are also preferred, as they make later operations with git history,
+whether it is bisecting, reverting, or something else, easier.
+
+_When submitting a pull request please do not include changes to the
+amalgamated distribution files. This means do not include them in your
+git commits!_
+
+When addressing review comments in a MR, please do not rebase/squash the
+commits immediately. Doing so makes it harder to review the new changes,
+slowing down the process of merging a MR. Instead, when addressing review
+comments, you should append new commits to the branch and only squash
+them into other commits when the MR is ready to be merged. We recommend
+creating new commits with `git commit --fixup` (or `--squash`) and then
+later squashing them with `git rebase --autosquash` to make things easier.
+
+
+
+## Testing your changes
+
+_Note: Running Catch2's tests requires Python3_
+
+
+Catch2 has multiple layers of tests that are then run as part of our CI.
+The most obvious one are the unit tests compiled into the `SelfTest`
+binary. These are then used in "Approval tests", which run (almost) all
+tests from `SelfTest` through a specific reporter and then compare the
+generated output with a known good output ("Baseline"). By default, new
+tests should be placed here.
+
+To configure a Catch2 build with just the basic tests, use the `basic-tests`
+preset, like so:
+
+```
+# Assuming you are in Catch2's root folder
+
+cmake -B basic-test-build -S . -DCMAKE_BUILD_TYPE=Debug --preset basic-tests
+```
+
+However, not all tests can be written as plain unit tests. For example,
+checking that Catch2 orders tests randomly when asked to, and that this
+random ordering is subset-invariant, is better done as an integration
+test using an external check script. Catch2 integration tests are written
+using CTest, either as a direct command invocation + pass/fail regex,
+or by delegating the check to a Python script.
+
+Catch2 is slowly gaining more and more types of tests, currently Catch2
+project also has buildable examples, "ExtraTests", and CMake config tests.
+Examples present a small and self-contained snippets of code that
+use Catch2's facilities for specific purpose. Currently they are assumed
+passing if they compile.
+
+ExtraTests then are expensive tests, that we do not want to run all the
+time. This can be either because they take a long time to run, or because
+they take a long time to compile, e.g. because they test compile time
+configuration and require separate compilation.
+
+Finally, CMake config tests test that you set Catch2's compile-time
+configuration options through CMake, using CMake options of the same name.
+
+These test categories can be enabled one by one, by passing
+`-DCATCH_BUILD_EXAMPLES=ON`, `-DCATCH_BUILD_EXTRA_TESTS=ON`, and
+`-DCATCH_ENABLE_CONFIGURE_TESTS=ON` when configuring the build.
+
+Catch2 also provides a preset that promises to enable _all_ test types,
+`all-tests`.
+
+The snippet below will build & run all tests, in `Debug` compilation mode.
+
+<!-- snippet: catch2-build-and-test -->
+<a id='snippet-catch2-build-and-test'></a>
+```sh
+# 1. Regenerate the amalgamated distribution (some tests are built against it)
+./tools/scripts/generateAmalgamatedFiles.py
+
+# 2. Configure the full test build
+cmake -B debug-build -S . -DCMAKE_BUILD_TYPE=Debug --preset all-tests
+
+# 3. Run the actual build
+cmake --build debug-build
+
+# 4. Run the tests using CTest
+ctest -j 4 --output-on-failure -C Debug --test-dir debug-build
+```
+<sup><a href='/tools/scripts/buildAndTest.sh#L6-L19' title='File snippet `catch2-build-and-test` was extracted from'>snippet source</a> | <a href='#snippet-catch2-build-and-test' title='Navigate to start of snippet `catch2-build-and-test`'>anchor</a></sup>
+<!-- endSnippet -->
+
+For convenience, the above commands are in the script `tools/scripts/buildAndTest.sh`, and can be run like this:
+
+```bash
+cd Catch2
+./tools/scripts/buildAndTest.sh
+```
+
+A Windows version of the script is available at `tools\scripts\buildAndTest.cmd`.
+
+If you added new tests, you will likely see `ApprovalTests` failure.
+After you check that the output difference is expected, you should
+run `tools/scripts/approve.py` to confirm them, and include these changes
+in your commit.
+
+
+## Writing documentation
+
+If you have added new feature to Catch2, it needs documentation, so that
+other people can use it as well. This section collects some technical
+information that you will need for updating Catch2's documentation, and
+possibly some generic advise as well.
+
+
+### Technicalities
+
+First, the technicalities:
+
+* If you have introduced a new document, there is a simple template you
+should use. It provides you with the top anchor mentioned to link to
+(more below), and also with a backlink to the top of the documentation:
+```markdown
+<a id="top"></a>
+# Cool feature
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/123456) in Catch2 X.Y.Z
+
+Text that explains how to use the cool feature.
+
+
+---
+
+[Home](Readme.md#top)
+```
+
+* Crosslinks to different pages should target the `top` anchor, like this
+`[link to contributing](contributing.md#top)`.
+
+* We introduced version tags to the documentation, which show users in
+which version a specific feature was introduced. This means that newly
+written documentation should be tagged with a placeholder, that will
+be replaced with the actual version upon release. There are 2 styles
+of placeholders used through the documentation, you should pick one that
+fits your text better (if in doubt, take a look at the existing version
+tags for other features).
+  * `> [Introduced](link-to-issue-or-PR) in Catch2 X.Y.Z` - this
+  placeholder is usually used after a section heading
+  * `> X (Y and Z) was [introduced](link-to-issue-or-PR) in Catch2 X.Y.Z`
+  - this placeholder is used when you need to tag a subpart of something,
+  e.g. a list
+
+* For pages with more than 4 subheadings, we provide a table of contents
+(ToC) at the top of the page. Because GitHub markdown does not support
+automatic generation of ToC, it has to be handled semi-manually. Thus,
+if you've added a new subheading to some page, you should add it to the
+ToC. This can be done either manually, or by running the
+`updateDocumentToC.py` script in the `scripts/` folder.
+
+### Contents
+
+Now, for some content tips:
+
+* Usage examples are good. However, having large code snippets inline
+can make the documentation less readable, and so the inline snippets
+should be kept reasonably short. To provide more complex compilable
+examples, consider adding new .cpp file to `examples/`.
+
+* Don't be afraid to introduce new pages. The current documentation
+tends towards long pages, but a lot of that is caused by legacy, and
+we know that some of the pages are overly big and unfocused.
+
+* When adding information to an existing page, please try to keep your
+formatting, style and changes consistent with the rest of the page.
+
+* Any documentation has multiple different audiences, that desire
+different information from the text. The 3 basic user-types to try and
+cover are:
+  * A beginner to Catch2, who requires closer guidance for the usage of Catch2.
+  * Advanced user of Catch2, who want to customize their usage.
+  * Experts, looking for full reference of Catch2's capabilities.
+
+
+## Writing code
+
+If want to contribute code, this section contains some simple rules
+and tips on things like code formatting, code constructions to avoid,
+and so on.
+
+### C++ standard version
+
+Catch2 currently targets C++14 as the minimum supported C++ version.
+Features from higher language versions should be used only sparingly,
+when the benefits from using them outweigh the maintenance overhead.
+
+Example of good use of polyfilling features is our use of `conjunction`,
+where if available we use `std::conjunction` and otherwise provide our
+own implementation. The reason it is good is that the surface area for
+maintenance is quite small, and `std::conjunction` can directly use
+compiler built-ins, thus providing significant compilation benefits.
+
+Example of bad use of polyfilling features would be to keep around two
+sets of metaprogramming in the stringification implementation, once
+using C++14 compliant TMP and once using C++17's `if constexpr`. While
+the C++17 would provide significant compilation speedups, the maintenance
+cost would be too high.
+
+
+### Formatting
+
+To make code formatting simpler for the contributors, Catch2 provides
+its own config for `clang-format`. However, because it is currently
+impossible to replicate existing Catch2's formatting in clang-format,
+using it to reformat a whole file would cause massive diffs. To keep
+the size of your diffs reasonable, you should only use clang-format
+on the newly changed code.
+
+
+### Code constructs to watch out for
+
+This section is a (sadly incomplete) listing of various constructs that
+are problematic and are not always caught by our CI infrastructure.
+
+
+#### Naked exceptions and exceptions-related function
+
+If you are throwing an exception, it should be done via `CATCH_ERROR`
+or `CATCH_RUNTIME_ERROR` in `internal/catch_enforce.hpp`. These macros will handle
+the differences between compilation with or without exceptions for you.
+However, some platforms (IAR) also have problems with exceptions-related
+functions, such as `std::current_exceptions`. We do not have IAR in our
+CI, but luckily there should not be too many reasons to use these.
+However, if you do, they should be kept behind a
+`CATCH_CONFIG_DISABLE_EXCEPTIONS` macro.
+
+
+#### Avoid `std::move` and `std::forward`
+
+`std::move` and `std::forward` provide nice semantic name for a specific
+`static_cast`. However, being function templates they have surprisingly
+high cost during compilation, and can also have a negative performance
+impact for low-optimization builds.
+
+You should be using `CATCH_MOVE` and `CATCH_FORWARD` macros from
+`internal/catch_move_and_forward.hpp` instead. They expand into the proper
+`static_cast`, and avoid the overhead of `std::move` and `std::forward`.
+
+
+#### Unqualified usage of functions from C's stdlib
+
+If you are using a function from C's stdlib, please include the header
+as `<cfoo>` and call the function qualified. The common knowledge that
+there is no difference is wrong, QNX and VxWorks won't compile if you
+include the header as `<cfoo>` and call the function unqualified.
+
+
+#### User-Defined Literals (UDL) for Catch2' types
+
+Due to messy standardese and ... not great ... implementation of
+`-Wreserved-identifier` in Clang, avoid declaring UDLs as
+```cpp
+Approx operator "" _a(long double);
+```
+and instead declare them as
+```cpp
+Approx operator ""_a(long double);
+```
+
+Notice that the second version does not have a space between the `""` and
+the literal suffix.
+
+
+
+### New source file template
+
+If you are adding new source file, there is a template you should use.
+Specifically, every source file should start with the licence header:
+```cpp
+
+    //              Copyright Catch2 Authors
+    // Distributed under the Boost Software License, Version 1.0.
+    //   (See accompanying file LICENSE.txt or copy at
+    //        https://www.boost.org/LICENSE_1_0.txt)
+
+    // SPDX-License-Identifier: BSL-1.0
+```
+
+The include guards for header files should follow the pattern `{FILENAME}_INCLUDED`.
+This means that for file `catch_matchers_foo.hpp`, the include guard should
+be `CATCH_MATCHERS_FOO_HPP_INCLUDED`, for `catch_generators_bar.hpp`, the include
+guard should be `CATCH_GENERATORS_BAR_HPP_INCLUDED`, and so on.
+
+
+### Adding new `CATCH_CONFIG` option
+
+When adding new `CATCH_CONFIG` option, there are multiple places to edit:
+  * `CMake/CatchConfigOptions.cmake` - this is used to generate the
+    configuration options in CMake, so that CMake frontends know about them.
+  * `docs/configuration.md` - this is where the options are documented
+  * `src/catch2/catch_user_config.hpp.in` - this is template for generating
+    `catch_user_config.hpp` which contains the materialized configuration
+  * `BUILD.bazel` - Bazel does not have configuration support like CMake,
+    and all expansions need to be done manually
+  * other files as needed, e.g. `catch2/internal/catch_config_foo.hpp`
+    for the logic that guards the configuration
+

+# Deprecations and incoming changes
+
+This page documents current deprecations and upcoming planned changes
+inside Catch2. The difference between these is that a deprecated feature
+will be removed, while a planned change to a feature means that the
+feature will behave differently, but will still be present. Obviously,
+either of these is a breaking change, and thus will not happen until
+at least the next major release.
+
+
+### `ParseAndAddCatchTests.cmake`
+
+The CMake/CTest integration using `ParseAndAddCatchTests.cmake` is deprecated,
+as it can be replaced by `Catch.cmake` that provides the function
+`catch_discover_tests` to get tests directly from a CMake target via the
+command line interface instead of parsing C++ code with regular expressions.
+
+
+### `CATCH_CONFIG_BAZEL_SUPPORT`
+
+Catch2 supports writing the Bazel JUnit XML output file when it is aware
+that is within a bazel testing environment. Originally there was no way
+to accurately probe the environment for this information so the flag
+`CATCH_CONFIG_BAZEL_SUPPORT` was added. This now deprecated. Bazel has now had a change
+where it will export `BAZEL_TEST=1` for purposes like the above. Catch2
+will now instead inspect the environment instead of relying on build configuration.
+
+### `IEventLister::skipTest( TestCaseInfo const& testInfo )`
+
+This event (including implementations in derived classes such as `ReporterBase`)
+is deprecated and will be removed in the next major release. It is currently
+invoked for all test cases that are not going to be executed due to the test run
+being aborted (when using `--abort` or `--abortx`). It is however
+**NOT** invoked for test cases that are [explicitly skipped using the `SKIP`
+macro](skipping-passing-failing.md#top).
+
+
+### Non-const function for `TEST_CASE_METHOD`
+
+> Deprecated in Catch2 vX.Y.Z
+
+Currently, the member function generated for `TEST_CASE_METHOD` is
+not `const` qualified. In the future, the generated member function will
+be `const` qualified, just as `TEST_CASE_PERSISTENT_FIXTURE` does.
+
+If you are mutating the fixture instance from within the test case, and
+want to keep doing so in the future, mark the mutated members as `mutable`.

+# Event Listeners
+
+An event listener is a bit like a reporter, in that it responds to various
+reporter events in Catch2, but it is not expected to write any output.
+Instead, an event listener performs actions within the test process, such
+as performing global initialization (e.g. of a C library), or cleaning out
+in-memory logs if they are not needed (the test case passed).
+
+Unlike reporters, each registered event listener is always active. Event
+listeners are always notified before reporter(s).
+
+To write your own event listener, you should derive from `Catch::TestEventListenerBase`,
+as it provides empty stubs for all reporter events, allowing you to
+only override events you care for. Afterwards you have to register it
+with Catch2 using `CATCH_REGISTER_LISTENER` macro, so that Catch2 knows
+about it and instantiates it before running tests.
+
+Example event listener:

+
+
+## How do I run global setup/teardown only if tests will be run?
+
+Write a custom [event listener](event-listeners.md#top) and place the
+global setup/teardown code into the `testRun*` events.
+
+
+## How do I clean up global state between running different tests?
+
+Write a custom [event listener](event-listeners.md#top) and place the
+cleanup code into either `testCase*` or `testCasePartial*` events,
+depending on how often the cleanup needs to happen.
+
+
+## Why cannot I derive from the built-in reporters?
+
+They are not made to be overridden, in that we do not attempt to maintain
+a consistent internal state if a member function is overridden, and by
+forbidding users from using them as a base class, we can refactor them
+as needed later.
+
+
+## What is Catch2's ABI stability policy?
+
+Catch2 provides no ABI stability guarantees whatsoever. Catch2 provides
+rich C++ interface, and trying to freeze its ABI would take a lot of
+pointless work.
+
+Catch2 is not designed to be distributed as dynamic library, and you
+should really be able to compile everything with the same compiler binary.
+
+
+## What is Catch2's API stability policy?
+
+Catch2 follows [semver](https://semver.org/) to the best of our ability.
+This means that we will not knowingly make backwards-incompatible changes
+without incrementing the major version number.
+
+
+## Does Catch2 support running tests in parallel?
+
+Not natively, no. We see running tests in parallel as the job of an
+external test runner, that can also run them in separate processes,
+support test execution timeouts and so on.
+
+However, Catch2 provides some tools that make the job of external test
+runners easier. [See the relevant section in our page on best
+practices](usage-tips.md#parallel-tests).
+
+
+## Can I compile Catch2 into a dynamic library?
+
+Yes, Catch2 supports the [standard CMake `BUILD_SHARED_LIBS`
+option](https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html).
+However, the dynamic library support is provided as-is. Catch2 does not
+provide API export annotations, and so you can only use it as a dynamic
+library on platforms that default to public visibility, or with tooling
+support to force export Catch2's API.
+
+
+## What repeatability guarantees does Catch2 provide?
+
+There are two places where it is meaningful to talk about Catch2's
+repeatability guarantees without taking into account user-provided
+code. First one is in the test case shuffling, and the second one is
+the output from random generators.
+
+Test case shuffling is repeatable across different platforms since v2.12.0,
+and it is also generally repeatable across versions, but we might break
+it from time to time. E.g. we broke repeatability with previous versions
+in v2.13.4 so that test cases with similar names are shuffled better.
+
+Since Catch2 3.5.0 the random generators use custom distributions,
+that should be repeatable across different platforms, with few caveats.
+For details see the section on random generators in the [Generator
+documentation](generators.md#random-number-generators-details).
+
+Before this version, random generators relied on distributions from
+platform's stdlib. We thus can provide no extra guarantee on top of the
+ones given by your platform. **Important: `<random>`'s distributions
+are not specified to be repeatable across different platforms.**
+
+
+## My build cannot find `catch2/catch_user_config.hpp`, how can I fix it?
+
+`catch2/catch_user_config.hpp` is a generated header that contains user
+compile time configuration. It is generated by CMake/Meson/Bazel during
+build. If you are not using either of these, your three options are to
+
+1) Build Catch2 separately using build tool that will generate the header
+2) Use the amalgamated files to build Catch2
+3) Use CMake to configure a build. This will generate the header and you
+   can copy it into your own checkout of Catch2.

+# Data Generators
+
+> Introduced in Catch2 2.6.0.
+
+Data generators (also known as _data driven/parametrized test cases_)
+let you reuse the same set of assertions across different input values.
+In Catch2, this means that they respect the ordering and nesting
+of the `TEST_CASE` and `SECTION` macros, and their nested sections
+are run once per each value in a generator.
+
+This is best explained with an example:
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 3, 5);
+    REQUIRE(is_odd(i));
+}
+```
+
+The "Generators" `TEST_CASE` will be entered 3 times, and the value of
+`i` will be 1, 3, and 5 in turn. `GENERATE`s can also be used multiple
+times at the same scope, in which case the result will be a cartesian
+product of all elements in the generators. This means that in the snippet
+below, the test case will be run 6 (2\*3) times.
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    auto j = GENERATE(3, 4, 5);
+}
+```
+
+There are 2 parts to generators in Catch2, the `GENERATE` macro together
+with the already provided generators, and the `IGenerator<T>` interface
+that allows users to implement their own generators.
+
+
+## Combining `GENERATE` and `SECTION`.
+
+`GENERATE` can be seen as an implicit `SECTION`, that goes from the place
+`GENERATE` is used, to the end of the scope. This can be used for various
+effects. The simplest usage is shown below, where the `SECTION` "one"
+runs 4 (2\*2) times, and `SECTION` "two" is run 6 times (2\*3).
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    SECTION("one") {
+        auto j = GENERATE(-3, -2);
+        REQUIRE(j < i);
+    }
+    SECTION("two") {
+        auto k = GENERATE(4, 5, 6);
+        REQUIRE(i != k);
+    }
+}
+```
+
+The specific order of the `SECTION`s will be "one", "one", "two", "two",
+"two", "one"...
+
+
+The fact that `GENERATE` introduces a virtual `SECTION` can also be used
+to make a generator replay only some `SECTION`s, without having to
+explicitly add a `SECTION`. As an example, the code below reports 3
+assertions, because the "first" section is run once, but the "second"
+section is run twice.
+
+```cpp
+TEST_CASE("GENERATE between SECTIONs") {
+    SECTION("first") { REQUIRE(true); }
+    auto _ = GENERATE(1, 2);
+    SECTION("second") { REQUIRE(true); }
+}
+```
+
+This can lead to surprisingly complex test flows. As an example, the test
+below will report 14 assertions:
+
+```cpp
+TEST_CASE("Complex mix of sections and generates") {
+    auto i = GENERATE(1, 2);
+    SECTION("A") {
+        SUCCEED("A");
+    }
+    auto j = GENERATE(3, 4);
+    SECTION("B") {
+        SUCCEED("B");
+    }
+    auto k = GENERATE(5, 6);
+    SUCCEED();
+}
+```
+
+> The ability to place `GENERATE` between two `SECTION`s was [introduced](https://github.com/catchorg/Catch2/issues/1938) in Catch2 2.13.0.
+
+## Provided generators
+
+Catch2's provided generator functionality consists of three parts,
+
+* `GENERATE` macro,  that serves to integrate generator expression with
+a test case,
+* 2 fundamental generators
+  * `SingleValueGenerator<T>` -- contains only single element
+  * `FixedValuesGenerator<T>` -- contains multiple elements
+* 5 generic generators that modify other generators
+  * `FilterGenerator<T, Predicate>` -- filters out elements from a generator
+  for which the predicate returns "false"
+  * `TakeGenerator<T>` -- takes first `n` elements from a generator
+  * `RepeatGenerator<T>` -- repeats output from a generator `n` times
+  * `MapGenerator<T, U, Func>` -- returns the result of applying `Func`
+  on elements from a different generator
+  * `ChunkGenerator<T>` -- returns chunks (inside `std::vector`) of n elements from a generator
+* 4 specific purpose generators
+  * `RandomIntegerGenerator<Integral>` -- generates random Integrals from range
+  * `RandomFloatGenerator<Float>` -- generates random Floats from range
+  * `RangeGenerator<T>(first, last)` -- generates all values inside a `[first, last)` arithmetic range
+  * `IteratorGenerator<T>` -- copies and returns values from an iterator range
+
+> `ChunkGenerator<T>`, `RandomIntegerGenerator<Integral>`, `RandomFloatGenerator<Float>` and `RangeGenerator<T>` were introduced in Catch2 2.7.0.
+
+> `IteratorGenerator<T>` was introduced in Catch2 2.10.0.
+
+The generators also have associated helper functions that infer their
+type, making their usage much nicer. These are
+
+* `value(T&&)` for `SingleValueGenerator<T>`
+* `values(std::initializer_list<T>)` for `FixedValuesGenerator<T>`
+* `table<Ts...>(std::initializer_list<std::tuple<Ts...>>)` for `FixedValuesGenerator<std::tuple<Ts...>>`
+* `filter(predicate, GeneratorWrapper<T>&&)` for `FilterGenerator<T, Predicate>`
+* `take(count, GeneratorWrapper<T>&&)` for `TakeGenerator<T>`
+* `repeat(repeats, GeneratorWrapper<T>&&)` for `RepeatGenerator<T>`
+* `map(func, GeneratorWrapper<T>&&)` for `MapGenerator<T, U, Func>` (map `U` to `T`, deduced from `Func`)
+* `map<T>(func, GeneratorWrapper<U>&&)` for `MapGenerator<T, U, Func>` (map `U` to `T`)
+* `chunk(chunk-size, GeneratorWrapper<T>&&)` for `ChunkGenerator<T>`
+* `random(IntegerOrFloat a, IntegerOrFloat b)` for `RandomIntegerGenerator` or `RandomFloatGenerator`
+* `range(Arithmetic start, Arithmetic end)` for `RangeGenerator<Arithmetic>` with a step size of `1`
+* `range(Arithmetic start, Arithmetic end, Arithmetic step)` for `RangeGenerator<Arithmetic>` with a custom step size
+* `from_range(InputIterator from, InputIterator to)` for `IteratorGenerator<T>`
+* `from_range(Container const&)` for `IteratorGenerator<T>`
+
+> `chunk()`, `random()` and both `range()` functions were introduced in Catch2 2.7.0.
+
+> `from_range` has been introduced in Catch2 2.10.0
+
+> `range()` for floating point numbers has been introduced in Catch2 2.11.0
+
+And can be used as shown in the example below to create a generator
+that returns 100 odd random number:
+
+```cpp
+TEST_CASE("Generating random ints", "[example][generator]") {
+    SECTION("Deducing functions") {
+        auto i = GENERATE(take(100, filter([](int i) { return i % 2 == 1; }, random(-100, 100))));
+        REQUIRE(i > -100);
+        REQUIRE(i < 100);
+        REQUIRE(i % 2 == 1);
+    }
+}
+```
+
+
+Apart from registering generators with Catch2, the `GENERATE` macro has
+one more purpose, and that is to provide simple way of generating trivial
+generators, as seen in the first example on this page, where we used it
+as `auto i = GENERATE(1, 2, 3);`. This usage converted each of the three
+literals into a single `SingleValueGenerator<int>` and then placed them all in
+a special generator that concatenates other generators. It can also be
+used with other generators as arguments, such as `auto i = GENERATE(0, 2,
+take(100, random(300, 3000)));`. This is useful e.g. if you know that
+specific inputs are problematic and want to test them separately/first.
+
+**For safety reasons, you cannot use variables inside the `GENERATE` macro.
+This is done because the generator expression _will_ outlive the outside
+scope and thus capturing references is dangerous. If you need to use
+variables inside the generator expression, make sure you thought through
+the lifetime implications and use `GENERATE_COPY` or `GENERATE_REF`.**
+
+> `GENERATE_COPY` and `GENERATE_REF` were introduced in Catch2 2.7.1.
+
+You can also override the inferred type by using `as<type>` as the first
+argument to the macro. This can be useful when dealing with string literals,
+if you want them to come out as `std::string`:
+
+```cpp
+TEST_CASE("type conversion", "[generators]") {
+    auto str = GENERATE(as<std::string>{}, "a", "bb", "ccc");
+    REQUIRE(str.size() > 0);
+}
+```
+
+
+### Random number generators: details
+
+> This section applies from Catch2 3.5.0. Before that, random generators
+> were a thin wrapper around distributions from `<random>`.
+
+All of the `random(a, b)` generators in Catch2 currently generate uniformly
+distributed number in closed interval \[a; b\]. This  is different from
+`std::uniform_real_distribution`, which should return numbers in interval
+\[a; b) (but due to rounding can end up returning b anyway), but the
+difference is intentional, so that `random(a, a)` makes sense. If there is
+enough interest from users, we can provide API to pick any of CC, CO, OC,
+or OO ranges.
+
+Unlike `std::uniform_int_distribution`, Catch2's generators also support
+various single-byte integral types, such as `char` or `bool`.
+
+
+#### Reproducibility
+
+Given the same seed, the output from the integral generators is fully
+reproducible across different platforms.
+
+For floating point generators, the situation is much more complex.
+Generally Catch2 only promises reproducibility (or even just correctness!)
+on platforms that obey the IEEE-754 standard. Furthermore, reproducibility
+only applies between binaries that perform floating point math in the
+same way, e.g. if you compile a binary targetting the x87 FPU and another
+one targetting SSE2 for floating point math, their results will vary.
+Similarly, binaries compiled with compiler flags that relax the IEEE-754
+adherence, e.g. `-ffast-math`, might provide different results than those
+compiled for strict IEEE-754 adherence.
+
+Finally, we provide zero guarantees on the reproducibility of generating
+`long double`s, as the internals of `long double` varies across different
+platforms.
+
+
+
+## Generator interface
+
+You can also implement your own generators, by deriving from the
+`IGenerator<T>` interface:
+
+```cpp
+template<typename T>
+struct IGenerator : GeneratorUntypedBase {
+    // via GeneratorUntypedBase:
+    // Attempts to move the generator to the next element.
+    // Returns true if successful (and thus has another element that can be read)
+    virtual bool next() = 0;
+
+    // Precondition:
+    // The generator is either freshly constructed or the last call to next() returned true
+    virtual T const& get() const = 0;
+
+    // Returns user-friendly string showing the current generator element
+    // Does not have to be overridden, IGenerator provides default implementation
+    virtual std::string stringifyImpl() const;
+};
+```
+
+However, to be able to use your custom generator inside `GENERATE`, it
+will need to be wrapped inside a `GeneratorWrapper<T>`.
+`GeneratorWrapper<T>` is a value wrapper around a
+`Catch::Detail::unique_ptr<IGenerator<T>>`.
+
+For full example of implementing your own generator, look into Catch2's
+examples, specifically
+[Generators: Create your own generator](../examples/300-Gen-OwnGenerator.cpp).
+
+
+### Handling empty generators
+
+The generator interface assumes that a generator always has at least one
+element. This is not always true, e.g. if the generator depends on an external
+datafile, the file might be missing.
+
+There are two ways to handle this, depending on whether you want this
+to be an error or not.
+
+ * If empty generator **is** an error, throw an exception in constructor.
+ * If empty generator **is not** an error, use the [`SKIP`](skipping-passing-failing.md#skipping-test-cases-at-runtime) in constructor.

+<a id="top"></a>
+# Known limitations
+
+Over time, some limitations of Catch2 emerged. Some of these are due
+to implementation details that cannot be easily changed, some of these
+are due to lack of development resources on our part, and some of these
+are due to plain old 3rd party bugs.
+
+
+## Implementation limits
+### Sections nested in loops
+
+If you are using `SECTION`s inside loops, you have to create them with
+different name per loop's iteration. The recommended way to do so is to
+incorporate the loop's counter into section's name, like so:
+
+```cpp
+TEST_CASE( "Looped section" ) {
+    for (char i = '0'; i < '5'; ++i) {
+        SECTION(std::string("Looped section ") + i) {
+            SUCCEED( "Everything is OK" );
+        }
+    }
+}
+```
+
+or with a `DYNAMIC_SECTION` macro (that was made for exactly this purpose):
+
+```cpp
+TEST_CASE( "Looped section" ) {
+    for (char i = '0'; i < '5'; ++i) {
+        DYNAMIC_SECTION( "Looped section " << i) {
+            SUCCEED( "Everything is OK" );
+        }
+    }
+}
+```
+
+### Tests might be run again if last section fails
+
+If the last section in a test fails, it might be run again. This is because
+Catch2 discovers `SECTION`s dynamically, as they are about to run, and
+if the last section in test case is aborted during execution (e.g. via
+the `REQUIRE` family of macros), Catch2 does not know that there are no
+more sections in that test case and must run the test case again.
+
+
+### MinGW/CygWin compilation (linking) is extremely slow
+
+Compiling Catch2 with MinGW can be exceedingly slow, especially during
+the linking step. As far as we can tell, this is caused by deficiencies
+in its default linker. If you can tell MinGW to instead use lld, via
+`-fuse-ld=lld`, the link time should drop down to reasonable length
+again.
+
+
+## Features
+This section outlines some missing features, what is their status and their possible workarounds.
+
+### Thread safe assertions
+Catch2's assertion macros are not thread safe. This does not mean that
+you cannot use threads inside Catch's test, but that only single thread
+can interact with Catch's assertions and other macros.
+
+This means that this is ok
+```cpp
+    std::vector<std::thread> threads;
+    std::atomic<int> cnt{ 0 };
+    for (int i = 0; i < 4; ++i) {
+        threads.emplace_back([&]() {
+            ++cnt; ++cnt; ++cnt; ++cnt;
+        });
+    }
+    for (auto& t : threads) { t.join(); }
+    REQUIRE(cnt == 16);
+```
+because only one thread passes the `REQUIRE` macro and this is not
+```cpp
+    std::vector<std::thread> threads;
+    std::atomic<int> cnt{ 0 };
+    for (int i = 0; i < 4; ++i) {
+        threads.emplace_back([&]() {
+            ++cnt; ++cnt; ++cnt; ++cnt;
+            CHECK(cnt == 16);
+        });
+    }
+    for (auto& t : threads) { t.join(); }
+    REQUIRE(cnt == 16);
+```
+
+We currently do not plan to support thread-safe assertions.
+
+
+### Process isolation in a test
+Catch does not support running tests in isolated (forked) processes. While this might in the future, the fact that Windows does not support forking and only allows full-on process creation and the desire to keep code as similar as possible across platforms, mean that this is likely to take significant development time, that is not currently available.
+
+
+### Running multiple tests in parallel
+
+Catch2 keeps test execution in one process strictly serial, and there
+are no plans to change this. If you find yourself with a test suite
+that takes too long to run and you want to make it parallel, you have
+to run multiple processes side by side.
+
+There are 2 basic ways to do that,
+* you can split your tests into multiple binaries, and run those binaries
+  in parallel
+* you can run the same test binary multiple times, but run a different
+  subset of the tests in each process
+
+There are multiple ways to achieve the latter, the easiest way is to use
+[test sharding](command-line.md#test-sharding).
+
+
+## 3rd party bugs
+
+This section outlines known bugs in 3rd party components (this means compilers, standard libraries, standard runtimes).
+
+
+### Visual Studio 2017 -- raw string literal in assert fails to compile
+
+There is a known bug in Visual Studio 2017 (VC 15), that causes compilation
+error when preprocessor attempts to stringize a raw string literal
+(`#` preprocessor directive is applied to it). This snippet is sufficient
+to trigger the compilation error:
+
+```cpp
+#include <catch2/catch_test_macros.hpp>
+
+TEST_CASE("test") {
+    CHECK(std::string(R"("\)") == "\"\\");
+}
+```
+
+Catch2 provides a workaround, by letting the user disable stringification
+of the original expression by defining `CATCH_CONFIG_DISABLE_STRINGIFICATION`,
+like so:
+```cpp
+#define CATCH_CONFIG_DISABLE_STRINGIFICATION
+#include <catch2/catch_test_macros.hpp>
+
+TEST_CASE("test") {
+    CHECK(std::string(R"("\)") == "\"\\");
+}
+```
+
+_Do note that this changes the output:_
+```
+catchwork\test1.cpp(6):
+PASSED:
+  CHECK( Disabled by CATCH_CONFIG_DISABLE_STRINGIFICATION )
+with expansion:
+  ""\" == ""\"
+```
+
+
+### Clang/G++ -- skipping leaf sections after an exception
+Some versions of `libc++` and `libstdc++` (or their runtimes) have a bug with `std::uncaught_exception()` getting stuck returning `true` after rethrow, even if there are no active exceptions. One such case is this snippet, which skipped the sections "a" and "b", when compiled against `libcxxrt` from the master branch
+```cpp
+#include <catch2/catch_test_macros.hpp>
+
+TEST_CASE("a") {
+    CHECK_THROWS(throw 3);
+}
+
+TEST_CASE("b") {
+    int i = 0;
+    SECTION("a") { i = 1; }
+    SECTION("b") { i = 2; }
+    CHECK(i > 0);
+}
+```
+
+If you are seeing a problem like this, i.e. weird test paths that trigger only under Clang with `libc++`, or only under very specific version of `libstdc++`, it is very likely you are seeing this. The only known workaround is to use a fixed version of your standard library.
+
+
+### Visual Studio 2022 -- can't compile assertion with the spaceship operator
+
+[The C++ standard requires that `std::foo_ordering` is only comparable with
+a literal 0](https://eel.is/c++draft/cmp#categories.pre-3). There are
+multiple strategies a stdlib implementation can take to achieve this, and
+MSVC's STL has changed the strategy they use between two releases of VS 2022.
+
+With the new strategy, `REQUIRE((a <=> b) == 0)` no longer compiles under
+MSVC. Note that Catch2 can compile code using MSVC STL's new strategy,
+but only when compiled with a C++20 conforming compiler. MSVC is currently
+not conformant enough, but `clang-cl` will compile the assertion above
+using MSVC STL without problem.
+
+This change got in with MSVC v19.37](https://godbolt.org/z/KG9obzdvE).

+# Logging macros
+
+Additional messages can be logged during a test case. Note that the messages logged with `INFO` are scoped and thus will not be reported if failure occurs in scope preceding the message declaration. An example:
+
+```cpp
+TEST_CASE("Foo") {
+    INFO("Test case start");
+    for (int i = 0; i < 2; ++i) {
+        INFO("The number is " << i);
+        CHECK(i == 0);
+    }
+}
+
+TEST_CASE("Bar") {
+    INFO("Test case start");
+    for (int i = 0; i < 2; ++i) {
+        INFO("The number is " << i);
+        CHECK(i == i);
+    }
+    CHECK(false);
+}
+```
+When the `CHECK` fails in the "Foo" test case, then two messages will be printed.
+```
+Test case start
+The number is 1
+```
+When the last `CHECK` fails in the "Bar" test case, then only one message will be printed: `Test case start`.
+
+## Logging without local scope
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1522) in Catch2 2.7.0.
+
+`UNSCOPED_INFO` is similar to `INFO` with two key differences:
+
+- Lifetime of an unscoped message is not tied to its own scope.
+- An unscoped message can be reported by the first following assertion only, regardless of the result of that assertion.
+
+In other words, lifetime of `UNSCOPED_INFO` is limited by the following assertion (or by the end of test case/section, whichever comes first) whereas lifetime of `INFO` is limited by its own scope.
+
+These differences make this macro useful for reporting information from helper functions or inner scopes. An example:
+
+```cpp
+void print_some_info() {
+    UNSCOPED_INFO("Info from helper");
+}
+
+TEST_CASE("Baz") {
+    print_some_info();
+    for (int i = 0; i < 2; ++i) {
+        UNSCOPED_INFO("The number is " << i);
+    }
+    CHECK(false);
+}
+
+TEST_CASE("Qux") {
+    INFO("First info");
+    UNSCOPED_INFO("First unscoped info");
+    CHECK(false);
+
+    INFO("Second info");
+    UNSCOPED_INFO("Second unscoped info");
+    CHECK(false);
+}
+```
+
+"Baz" test case prints:
+```
+Info from helper
+The number is 0
+The number is 1
+```
+
+With "Qux" test case, two messages will be printed when the first `CHECK` fails:
+```
+First info
+First unscoped info
+```
+
+"First unscoped info" message will be cleared after the first `CHECK`, while "First info" message will persist until the end of the test case. Therefore, when the second `CHECK` fails, three messages will be printed:
+```
+First info
+Second info
+Second unscoped info
+```
+
+## Streaming macros
+
+All these macros allow heterogeneous sequences of values to be streaming using the insertion operator (```<<```) in the same way that std::ostream, std::cout, etc support it.
+
+E.g.:
+```c++
+INFO( "The number is " << i );
+```
+
+(Note that there is no initial ```<<``` - instead the insertion sequence is placed in parentheses.)
+These macros come in three forms:
+
+**INFO(** _message expression_ **)**
+
+The message is logged to a buffer, but only reported with next assertions that are logged. This allows you to log contextual information in case of failures which is not shown during a successful test run (for the console reporter, without -s). Messages are removed from the buffer at the end of their scope, so may be used, for example, in loops.
+
+_Note that in Catch2 2.x.x `INFO` can be used without a trailing semicolon as there is a trailing semicolon inside macro.
+This semicolon will be removed with next major version. It is highly advised to use a trailing semicolon after `INFO` macro._
+
+**UNSCOPED_INFO(** _message expression_ **)**
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1522) in Catch2 2.7.0.
+
+Similar to `INFO`, but messages are not limited to their own scope: They are removed from the buffer after each assertion, section or test case, whichever comes first.
+
+**WARN(** _message expression_ **)**
+
+The message is always reported but does not fail the test.
+
+**SUCCEED(** _message expression_ **)**
+
+The message is reported and the test case succeeds.
+
+**FAIL(** _message expression_ **)**
+
+The message is reported and the test case fails.
+
+**FAIL_CHECK(** _message expression_ **)**
+
+AS `FAIL`, but does not abort the test
+
+## Quickly capture value of variables or expressions
+
+**CAPTURE(** _expression1_, _expression2_, ... **)**
+
+Sometimes you just want to log a value of variable, or expression. For
+convenience, we provide the `CAPTURE` macro, that can take a variable,
+or an expression, and prints out that variable/expression and its value
+at the time of capture.
+
+e.g. `CAPTURE( theAnswer );` will log message "theAnswer := 42", while
+```cpp
+int a = 1, b = 2, c = 3;
+CAPTURE( a, b, c, a + b, c > b, a == 1);
+```
+will log a total of 6 messages:
+```
+a := 1
+b := 2
+c := 3
+a + b := 3
+c > b := true
+a == 1 := true
+```
+
+You can also capture expressions that use commas inside parentheses
+(e.g. function calls), brackets, or braces (e.g. initializers). To
+properly capture expression that contains template parameters list
+(in other words, it contains commas between angle brackets), you need
+to enclose the expression inside parentheses:
+`CAPTURE( (std::pair<int, int>{1, 2}) );`

+[Writing custom matchers (new style)](#writing-custom-matchers-new-style)<br>
+
+Matchers, as popularized by the [Hamcrest](https://en.wikipedia.org/wiki/Hamcrest)
+framework are an alternative way to write assertions, useful for tests
+where you work with complex types or need to assert more complex
+properties. Matchers are easily composable and users can write their
+own and combine them with the Catch2-provided matchers seamlessly.
+
+
+## Using Matchers
+
+Matchers are most commonly used in tandem with the `REQUIRE_THAT` or
+`CHECK_THAT` macros. The `REQUIRE_THAT` macro takes two arguments,
+the first one is the input (object/value) to test, the second argument
+is the matcher itself.
+
+For example, to assert that a string ends with the "as a service"
+substring, you can write the following assertion
+
+```cpp
+using Catch::Matchers::EndsWith;
+
+REQUIRE_THAT( getSomeString(), EndsWith("as a service") );
+```
+
+Individual matchers can also be combined using the C++ logical
+operators, that is `&&`, `||`, and `!`, like so:
+
+```cpp
+using Catch::Matchers::EndsWith;
+using Catch::Matchers::ContainsSubstring;
+
+REQUIRE_THAT( getSomeString(),
+              EndsWith("as a service") && ContainsSubstring("web scale"));
+```
+
+The example above asserts that the string returned from `getSomeString`
+_both_ ends with the suffix "as a service" _and_ contains the string
+"web scale" somewhere.
+
+
+Both of the string matchers used in the examples above live in the
+`catch_matchers_string.hpp` header, so to compile the code above also
+requires `#include <catch2/matchers/catch_matchers_string.hpp>`.
+
+### Combining operators and lifetimes
+
+**IMPORTANT**: The combining operators do not take ownership of the
+matcher objects being combined.
+
+This means that if you store combined matcher object, you have to ensure
+that the individual matchers being combined outlive the combined matcher.
+Note that the negation matcher from `!` also counts as combining matcher
+for this.
+
+Explained on an example, this is fine
+```cpp
+CHECK_THAT(value, WithinAbs(0, 2e-2) && !WithinULP(0., 1));
+```
+
+and so is this
+```cpp
+auto is_close_to_zero = WithinAbs(0, 2e-2);
+auto is_zero          = WithinULP(0., 1);
+
+CHECK_THAT(value, is_close_to_zero && !is_zero);
+```
+
+but this is not
+```cpp
+auto is_close_to_zero = WithinAbs(0, 2e-2);
+auto is_zero          = WithinULP(0., 1);
+auto is_close_to_but_not_zero = is_close_to_zero && !is_zero;
+
+CHECK_THAT(a_value, is_close_to_but_not_zero); // UAF
+```
+
+because `!is_zero` creates a temporary instance of Negation matcher,
+which the `is_close_to_but_not_zero` refers to. After the line ends,
+the temporary is destroyed and the combined `is_close_to_but_not_zero`
+matcher now refers to non-existent object, so using it causes use-after-free.
+
+
+## Built-in matchers
+
+Every matcher provided by Catch2 is split into 2 parts, a factory
+function that lives in the `Catch::Matchers` namespace, and the actual
+matcher type that is in some deeper namespace and should not be used by
+the user. In the examples above, we used `Catch::Matchers::Contains`.
+This is the factory function for the
+`Catch::Matchers::StdString::ContainsMatcher` type that does the actual
+matching.
+
+Out of the box, Catch2 provides the following matchers:
+
+
+### `std::string` matchers
+
+Catch2 provides 5 different matchers that work with `std::string`,
+* `StartsWith(std::string str, CaseSensitive)`,
+* `EndsWith(std::string str, CaseSensitive)`,
+* `ContainsSubstring(std::string str, CaseSensitive)`,
+* `Equals(std::string str, CaseSensitive)`, and
+* `Matches(std::string str, CaseSensitive)`.
+
+The first three should be fairly self-explanatory, they succeed if
+the argument starts with `str`, ends with `str`, or contains `str`
+somewhere inside it.
+
+The `Equals` matcher matches a string if (and only if) the argument
+string is equal to `str`.
+
+Finally, the `Matches` matcher performs an ECMAScript regex match using
+`str` against the argument string. It is important to know that
+the match is performed against the string as a whole, meaning that
+the regex `"abc"` will not match input string `"abcd"`. To match
+`"abcd"`, you need to use e.g. `"abc.*"` as your regex.
+
+The second argument sets whether the matching should be case-sensitive
+or not. By default, it is case-sensitive.
+
+> `std::string` matchers live in `catch2/matchers/catch_matchers_string.hpp`
+
+
+### Vector matchers
+
+_Vector matchers have been deprecated in favour of the generic
+range matchers with the same functionality._
+
+Catch2 provides 5 built-in matchers that work on `std::vector`.
+
+These are
+
+ * `Contains` which checks whether a specified vector is present in the result
+ * `VectorContains` which checks whether a specified element is present in the result
+ * `Equals` which checks whether the result is exactly equal (order matters) to a specific vector
+ * `UnorderedEquals` which checks whether the result is equal to a specific vector under a permutation
+ * `Approx` which checks whether the result is "approx-equal" (order matters, but comparison is done via `Approx`) to a specific vector
+> Approx matcher was [introduced](https://github.com/catchorg/Catch2/issues/1499) in Catch2 2.7.2.
+
+An example usage:
+```cpp
+    std::vector<int> some_vec{ 1, 2, 3 };
+    REQUIRE_THAT(some_vec, Catch::Matchers::UnorderedEquals(std::vector<int>{ 3, 2, 1 }));
+```
+
+This assertions will pass, because the elements given to the matchers
+are a permutation of the ones in `some_vec`.
+
+> vector matchers live in `catch2/matchers/catch_matchers_vector.hpp`
+
+
+### Floating point matchers
+
+Catch2 provides 4 matchers that target floating point numbers. These
+are:
+
+* `WithinAbs(double target, double margin)`,
+* `WithinULP(FloatingPoint target, uint64_t maxUlpDiff)`, and
+* `WithinRel(FloatingPoint target, FloatingPoint eps)`.
+* `IsNaN()`
+
+> `WithinRel` matcher was introduced in Catch2 2.10.0
+
+> `IsNaN` matcher was introduced in Catch2 3.3.2.
+
+The first three serve to compare two floating pointe numbers. For more
+details about how they work, read [the docs on comparing floating point
+numbers](comparing-floating-point-numbers.md#floating-point-matchers).
+
+`IsNaN` then does exactly what it says on the tin. It matches the input
+if it is a NaN (Not a Number). The advantage of using it over just plain
+`REQUIRE(std::isnan(x))`, is that if the check fails, with `REQUIRE` you
+won't see the value of `x`, but with `REQUIRE_THAT(x, IsNaN())`, you will.
+
+
+### Miscellaneous matchers
+
+Catch2 also provides some matchers and matcher utilities that do not
+quite fit into other categories.
+
+The first one of them is the `Predicate(Callable pred, std::string description)`
+matcher. It creates a matcher object that calls `pred` for the provided
+argument. The `description` argument allows users to set what the
+resulting matcher should self-describe as if required.
+
+Do note that you will need to explicitly specify the type of the
+argument, like in this example:
+
+```cpp
+REQUIRE_THAT("Hello olleH",
+             Predicate<std::string>(
+                 [] (std::string const& str) -> bool { return str.front() == str.back(); },
+                 "First and last character should be equal")
+);
+```
+
+> the predicate matcher lives in `catch2/matchers/catch_matchers_predicate.hpp`
+
+
+The other miscellaneous matcher utility is exception matching.
+
+
+#### Matching exceptions
+
+Because exceptions are a bit special, Catch2 has a separate macro for them.
+
+
+The basic form is
+
+```
+REQUIRE_THROWS_MATCHES(expr, ExceptionType, Matcher)
+```
+
+and it checks that the `expr` throws an exception, that exception is derived
+from the `ExceptionType` type, and then `Matcher::match` is called on
+the caught exception.
+
+> `REQUIRE_THROWS_MATCHES` macro lives in `catch2/matchers/catch_matchers.hpp`
+
+For one-off checks you can use the `Predicate` matcher above, e.g.
+
+```cpp
+REQUIRE_THROWS_MATCHES(parse(...),
+                       parse_error,
+                       Predicate<parse_error>([] (parse_error const& err) -> bool { return err.line() == 1; })
+);
+```
+
+but if you intend to thoroughly test your error reporting, I recommend
+defining a specialized matcher.
+
+
+Catch2 also provides 2 built-in matchers for checking the error message
+inside an exception (it must be derived from `std::exception`):
+* `Message(std::string message)`.
+* `MessageMatches(Matcher matcher)`.
+
+> `MessageMatches` was [introduced](https://github.com/catchorg/Catch2/pull/2570) in Catch2 3.3.0
+
+`Message` checks that the exception's
+message, as returned from `what` is exactly equal to `message`.
+
+`MessageMatches` applies the provided matcher on the exception's
+message, as returned from `what`. This is useful in conjunctions with the `std::string` matchers (e.g. `StartsWith`)
+
+Example use:
+```cpp
+REQUIRE_THROWS_MATCHES(throwsDerivedException(),  DerivedException,  Message("DerivedException::what"));
+REQUIRE_THROWS_MATCHES(throwsDerivedException(),  DerivedException,  MessageMatches(StartsWith("DerivedException")));
+```
+
+> the exception message matchers live in `catch2/matchers/catch_matchers_exception.hpp`
+
+
+### Generic range Matchers
+
+> Generic range matchers were introduced in Catch2 3.0.1
+
+Catch2 also provides some matchers that use the new style matchers
+definitions to handle generic range-like types. These are:
+
+* `IsEmpty()`
+* `SizeIs(size_t target_size)`
+* `SizeIs(Matcher size_matcher)`
+* `Contains(T&& target_element, Comparator = std::equal_to<>{})`
+* `Contains(Matcher element_matcher)`
+* `AllMatch(Matcher element_matcher)`
+* `AnyMatch(Matcher element_matcher)`
+* `NoneMatch(Matcher element_matcher)`
+* `AllTrue()`, `AnyTrue()`, `NoneTrue()`
+* `RangeEquals(TargetRangeLike&&, Comparator = std::equal_to<>{})`
+* `UnorderedRangeEquals(TargetRangeLike&&, Comparator = std::equal_to<>{})`
+
+> `IsEmpty`, `SizeIs`, `Contains` were introduced in Catch2 3.0.1
+
+> `All/Any/NoneMatch` were introduced in Catch2 3.0.1
+
+> `All/Any/NoneTrue` were introduced in Catch2 3.1.0
+
+> `RangeEquals` and `UnorderedRangeEquals` matchers were [introduced](https://github.com/catchorg/Catch2/pull/2377) in Catch2 3.3.0
+
+`IsEmpty` should be self-explanatory. It successfully matches objects
+that are empty according to either `std::empty`, or ADL-found `empty`
+free function.
+
+`SizeIs` checks range's size. If constructed with `size_t` arg, the
+matchers accepts ranges whose size is exactly equal to the arg. If
+constructed from another matcher, then the resulting matcher accepts
+ranges whose size is accepted by the provided matcher.
+
+`Contains` accepts ranges that contain specific element. There are
+again two variants, one that accepts the desired element directly,
+in which case a range is accepted if any of its elements is equal to
+the target element. The other variant is constructed from a matcher,
+in which case a range is accepted if any of its elements is accepted
+by the provided matcher.
+
+`AllMatch`, `NoneMatch`, and `AnyMatch` match ranges for which either
+all, none, or any of the contained elements matches the given matcher,
+respectively.
+
+`AllTrue`, `NoneTrue`, and `AnyTrue` match ranges for which either
+all, none, or any of the contained elements are `true`, respectively.
+It works for ranges of `bool`s and ranges of elements (explicitly)
+convertible to `bool`.
+
+`RangeEquals` compares the range that the matcher is constructed with
+(the "target range") against the range to be tested, element-wise. The
+match succeeds if all elements from the two ranges compare equal (using
+`operator==` by default). The ranges do not need to be the same type,
+and the element types do not need to be the same, as long as they are
+comparable. (e.g. you may compare `std::vector<int>` to `std::array<char>`).
+
+`UnorderedRangeEquals` is similar to `RangeEquals`, but the order
+does not matter. For example "1, 2, 3" would match "3, 2, 1", but not
+"1, 1, 2, 3" As with `RangeEquals`, `UnorderedRangeEquals` compares
+the individual elements using `operator==` by default.
+
+Both `RangeEquals` and `UnorderedRangeEquals` optionally accept a
+predicate which can be used to compare the containers element-wise.
+
+To check a container elementwise against a given matcher, use
+`AllMatch`.
+
+
+## Writing custom matchers (old style)
+
+The old style of writing matchers has been introduced back in Catch
+Classic. To create an old-style matcher, you have to create your own
+type that derives from `Catch::Matchers::MatcherBase<ArgT>`, where
+`ArgT` is the type your matcher works for. Your type has to override
+two methods, `bool match(ArgT const&) const`,
+and `std::string describe() const`.
+
+As the name suggests, `match` decides whether the provided argument
+is matched (accepted) by the matcher. `describe` then provides a
+human-oriented description of what the matcher does.
+
+We also recommend that you create factory function, just like Catch2
+does, but that is mostly useful for template argument deduction for
+templated matchers (assuming you do not have CTAD available).
+
+To combine these into an example, let's say that you want to write
+a matcher that decides whether the provided argument is a number
+within certain range. We will call it `IsBetweenMatcher<T>`:
+
+```c++
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/matchers/catch_matchers.hpp>
+// ...
+
+
+template <typename T>
+class IsBetweenMatcher : public Catch::Matchers::MatcherBase<T> {
+    T m_begin, m_end;
+public:
+    IsBetweenMatcher(T begin, T end) : m_begin(begin), m_end(end) {}
+
+    bool match(T const& in) const override {
+        return in >= m_begin && in <= m_end;
+    }
+
+    std::string describe() const override {
+        std::ostringstream ss;
+        ss << "is between " << m_begin << " and " << m_end;
+        return ss.str();
+    }
+};
+
+template <typename T>
+IsBetweenMatcher<T> IsBetween(T begin, T end) {
+    return { begin, end };
+}
+
+// ...
+
+TEST_CASE("Numbers are within range") {
+    // infers `double` for the argument type of the matcher
+    CHECK_THAT(3., IsBetween(1., 10.));
+    // infers `int` for the argument type of the matcher
+    CHECK_THAT(100, IsBetween(1, 10));
+}
+```
+
+Obviously, the code above can be improved somewhat, for example you
+might want to `static_assert` over the fact that `T` is an arithmetic
+type... or generalize the matcher to cover any type for which the user
+can provide a comparison function object.
+
+Note that while any matcher written using the old style can also be
+written using the new style, combining old style matchers should
+generally compile faster. Also note that you can combine old and new
+style matchers arbitrarily.
+
+> `MatcherBase` lives in `catch2/matchers/catch_matchers.hpp`
+
+
+## Writing custom matchers (new style)
+
+> New style matchers were introduced in Catch2 3.0.1
+
+To create a new-style matcher, you have to create your own type that
+derives from `Catch::Matchers::MatcherGenericBase`. Your type has to
+also provide two methods, `bool match( ... ) const` and overridden
+`std::string describe() const`.
+
+Unlike with old-style matchers, there are no requirements on how
+the `match` member function takes its argument. This means that the
+argument can be taken by value or by mutating reference, but also that
+the matcher's `match` member function can be templated.
+
+This allows you to write more complex matcher, such as a matcher that
+can compare one range-like (something that responds to `begin` and
+`end`) object to another, like in the following example:
+
+```cpp
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/matchers/catch_matchers_templated.hpp>
+// ...
+
+template<typename Range>
+struct EqualsRangeMatcher : Catch::Matchers::MatcherGenericBase {
+    EqualsRangeMatcher(Range const& range):
+        range{ range }
+    {}
+

+    }
+
+    std::string describe() const override {

+Do note that while you can rewrite any matcher from the old style to

+# Migrating from v2 to v3
+
+v3 is the next major version of Catch2 and brings three significant changes:
+ * Catch2 is now split into multiple headers
+ * Catch2 is now compiled as a static library
+ * C++14 is the minimum required C++ version
+
+There are many reasons why we decided to go from the old single-header
+distribution model to a more standard library distribution model. The
+big one is compile-time performance, but moving over to a split header
+distribution model also improves the future maintainability and
+extendability of the codebase. For example v3 adds a new kind of matchers
+without impacting the compilation times of users that do not use matchers
+in their tests. The new model is also more friendly towards package
+managers, such as vcpkg and Conan.
+
+The result of this move is a significant improvement in compilation
+times, e.g. the inclusion overhead of Catch2 in the common case has been
+reduced by roughly 80%. The improved ease of maintenance also led to
+various runtime performance improvements and the introduction of new features.
+For details, look at [the release notes of 3.0.1](release-notes.md#301).
+
+_Note that we still provide one header + one translation unit (TU)
+distribution but do not consider it the primarily supported option. You
+should also expect that the compilation times will be worse if you use
+this option._
+
+
+## How to migrate projects from v2 to v3
+
+To migrate to v3, there are two basic approaches to do so.
+
+1. Use `catch_amalgamated.hpp` and `catch_amalgamated.cpp`.
+2. Build Catch2 as a proper (static) library, and move to piecewise headers
+
+Doing 1 means downloading the [amalgamated header](/extras/catch_amalgamated.hpp)
+and the [amalgamated sources](/extras/catch_amalgamated.cpp) from `extras`,
+dropping them into your test project, and rewriting your includes from
+`<catch2/catch.hpp>` to `"catch_amalgamated.hpp"` (or something similar,
+based on how you set up your paths).
+
+The disadvantage of using this approach are increased compilation times,
+at least compared to the second approach, but it does let you avoid
+dealing with consuming libraries in your build system of choice.
+
+
+However, we recommend doing 2, and taking extra time to migrate to v3
+properly. This lets you reap the benefits of significantly improved
+compilation times in the v3 version. The basic steps to do so are:
+
+1. Change your CMakeLists.txt to link against `Catch2WithMain` target if
+you use Catch2's default main. (If you do not, keep linking against
+the `Catch2` target.). If you use pkg-config, change `pkg-config catch2` to
+`pkg-config catch2-with-main`.
+2. Delete TU with `CATCH_CONFIG_RUNNER` or `CATCH_CONFIG_MAIN` defined,
+as it is no longer needed.
+3. Change `#include <catch2/catch.hpp>` to `#include <catch2/catch_all.hpp>`
+4. Check that everything compiles. You might have to modify namespaces,
+or perform some other changes (see the
+[Things that can break during porting](#things-that-can-break-during-porting)
+section for the most common things).
+5. Start migrating your test TUs from including `<catch2/catch_all.hpp>`
+to piecemeal includes. You will likely want to start by including
+`<catch2/catch_test_macros.hpp>`, and then go from there. (see
+[other notes](#other-notes) for further ideas)
+
+## Other notes
+
+* The main test include is now `<catch2/catch_test_macros.hpp>`
+
+* Big "subparts" like Matchers, or Generators, have their own folder, and
+also their own "big header", so if you just want to include all matchers,
+you can include `<catch2/matchers/catch_matchers_all.hpp>`,
+or `<catch2/generators/catch_generators_all.hpp>`
+
+
+## Things that can break during porting
+
+* The namespaces of Matchers were flattened and cleaned up.
+
+Matchers are no longer declared deep within an internal namespace and
+then brought up into `Catch` namespace. All Matchers now live in the
+`Catch::Matchers` namespace.
+
+* The `Contains` string matcher was renamed to `ContainsSubstring`.
+
+* The reporter interfaces changed in a breaking manner.
+
+If you are using a custom reporter or listener, you will likely need to
+modify them to conform to the new interfaces. Unlike before in v2,
+the [interfaces](reporters.md#top) and the [events](reporter-events.md#top)
+are now documented.

+# Other macros
+
+This page serves as a reference for macros that are not documented
+elsewhere. For now, these macros are separated into 2 rough categories,
+"assertion related macros" and "test case related macros".
+
+## Assertion related macros
+
+* `CHECKED_IF` and `CHECKED_ELSE`
+
+`CHECKED_IF( expr )` is an `if` replacement, that also applies Catch2's
+stringification machinery to the _expr_ and records the result. As with
+`if`, the block after a `CHECKED_IF` is entered only if the expression
+evaluates to `true`. `CHECKED_ELSE( expr )` work similarly, but the block
+is entered only if the _expr_ evaluated to `false`.
+
+> `CHECKED_X` macros were changed to not count as failure in Catch2 3.0.1.
+
+Example:
+```cpp
+int a = ...;
+int b = ...;
+CHECKED_IF( a == b ) {
+    // This block is entered when a == b
+} CHECKED_ELSE ( a == b ) {
+    // This block is entered when a != b
+}
+```
+
+* `CHECK_NOFAIL`
+
+`CHECK_NOFAIL( expr )` is a variant of `CHECK` that does not fail the test
+case if _expr_ evaluates to `false`. This can be useful for checking some
+assumption, that might be violated without the test necessarily failing.
+
+Example output:
+```
+main.cpp:6:
+FAILED - but was ok:
+  CHECK_NOFAIL( 1 == 2 )
+
+main.cpp:7:
+PASSED:
+  CHECK( 2 == 2 )
+```
+
+* `SUCCEED`
+
+`SUCCEED( msg )` is mostly equivalent with `INFO( msg ); REQUIRE( true );`.
+In other words, `SUCCEED` is for cases where just reaching a certain line
+means that the test has been a success.
+
+Example usage:
+```cpp
+TEST_CASE( "SUCCEED showcase" ) {
+    int I = 1;
+    SUCCEED( "I is " << I );
+}
+```
+
+* `STATIC_REQUIRE` and `STATIC_CHECK`
+
+> `STATIC_REQUIRE` was [introduced](https://github.com/catchorg/Catch2/issues/1362) in Catch2 2.4.2.
+
+`STATIC_REQUIRE( expr )` is a macro that can be used the same way as a
+`static_assert`, but also registers the success with Catch2, so it is
+reported as a success at runtime. The whole check can also be deferred
+to the runtime, by defining `CATCH_CONFIG_RUNTIME_STATIC_REQUIRE` before
+including the Catch2 header.
+
+Example:
+```cpp
+TEST_CASE("STATIC_REQUIRE showcase", "[traits]") {
+    STATIC_REQUIRE( std::is_void<void>::value );
+    STATIC_REQUIRE_FALSE( std::is_void<int>::value );
+}
+```
+
+> `STATIC_CHECK` was [introduced](https://github.com/catchorg/Catch2/pull/2318) in Catch2 3.0.1.
+
+`STATIC_CHECK( expr )` is equivalent to `STATIC_REQUIRE( expr )`, with the
+difference that when `CATCH_CONFIG_RUNTIME_STATIC_REQUIRE` is defined, it
+becomes equivalent to `CHECK` instead of `REQUIRE`.
+
+Example:
+```cpp
+TEST_CASE("STATIC_CHECK showcase", "[traits]") {
+    STATIC_CHECK( std::is_void<void>::value );
+    STATIC_CHECK_FALSE( std::is_void<int>::value );
+}
+```
+
+## Test case related macros
+
+* `REGISTER_TEST_CASE`
+
+`REGISTER_TEST_CASE( function, description )` let's you register
+a `function` as a test case. The function has to have `void()` signature,
+the description can contain both name and tags.
+
+Example:
+```cpp
+REGISTER_TEST_CASE( someFunction, "ManuallyRegistered", "[tags]" );
+```
+
+_Note that the registration still has to happen before Catch2's session
+is initiated. This means that it either needs to be done in a global
+constructor, or before Catch2's session is created in user's own main._
+
+
+* `DYNAMIC_SECTION`
+
+> Introduced in Catch2 2.3.0.
+
+`DYNAMIC_SECTION` is a `SECTION` where the user can use `operator<<` to
+create the final name for that section. This can be useful with e.g.
+generators, or when creating a `SECTION` dynamically, within a loop.
+
+Example:
+```cpp
+TEST_CASE( "looped SECTION tests" ) {
+    int a = 1;
+
+    for( int b = 0; b < 10; ++b ) {
+        DYNAMIC_SECTION( "b is currently: " << b ) {
+            CHECK( b > a );
+        }
+    }
+}
+```

+# Supplying main() yourself

+[Let Catch2 take full control of args and config](#let-catch2-take-full-control-of-args-and-config)<br>
+[Amending the Catch2 config](#amending-the-catch2-config)<br>
+[Adding your own command line options](#adding-your-own-command-line-options)<br>
+[Version detection](#version-detection)<br>
+
+The easiest way to use Catch2 is to use its own `main` function, and let
+it handle the command line arguments. This is done by linking against
+Catch2Main library, e.g. through the [CMake target](cmake-integration.md#cmake-targets),
+or pkg-config files.
+
+If you want to provide your own `main`, then you should link against
+the static library (target) only, without the main part. You will then
+have to write your own `main` and call into Catch2 test runner manually.
+
+Below are some basic recipes on what you can do supplying your own main.
+
+
+## Let Catch2 take full control of args and config
+
+This is useful if you just need to have code that executes before/after
+Catch2 runs tests.
+
+```cpp
+#include <catch2/catch_session.hpp>
+
+int main( int argc, char* argv[] ) {
+  // your setup ...
+
+  int result = Catch::Session().run( argc, argv );
+
+  // your clean-up...
+
+  return result;
+}
+```
+
+_Note that if you only want to run some set up before tests are run, it
+might be simpler to use [event listeners](event-listeners.md#top) instead._
+
+
+## Amending the Catch2 config
+
+If you want Catch2 to process command line arguments, but also want to
+programmatically change the resulting configuration of Catch2 run,
+you can do it in two ways:
+
+```c++
+int main( int argc, char* argv[] ) {
+  Catch::Session session; // There must be exactly one instance
+
+  // writing to session.configData() here sets defaults
+  // this is the preferred way to set them
+
+  int returnCode = session.applyCommandLine( argc, argv );
+  if( returnCode != 0 ) // Indicates a command line error
+        return returnCode;
+
+  // writing to session.configData() or session.Config() here
+  // overrides command line args
+  // only do this if you know you need to
+
+  int numFailed = session.run();
+
+  // numFailed is clamped to 255 as some unices only use the lower 8 bits.
+  // This clamping has already been applied, so just return it here
+  // You can also do any post run clean-up here
+  return numFailed;
+}
+```
+
+If you want full control of the configuration, don't call `applyCommandLine`.
+
+
+## Adding your own command line options
+
+You can add new command line options to Catch2, by composing the premade
+CLI parser (called Clara), and add your own options.
+
+```cpp
+int main( int argc, char* argv[] ) {
+  Catch::Session session; // There must be exactly one instance
+
+  int height = 0; // Some user variable you want to be able to set
+
+  // Build a new parser on top of Catch2's
+  using namespace Catch::Clara;
+  auto cli
+    = session.cli()           // Get Catch2's command line parser
+    | Opt( height, "height" ) // bind variable to a new option, with a hint string
+        ["-g"]["--height"]    // the option names it will respond to
+        ("how high?");        // description string for the help output
+
+  // Now pass the new composite back to Catch2 so it uses that
+  session.cli( cli );
+
+  // Let Catch2 (using Clara) parse the command line
+  int returnCode = session.applyCommandLine( argc, argv );
+  if( returnCode != 0 ) // Indicates a command line error
+      return returnCode;
+
+  // if set on the command line then 'height' is now set at this point
+  if( height > 0 )
+      std::cout << "height: " << height << std::endl;
+
+  return session.run();
+}
+```
+
+See the [Clara documentation](https://github.com/catchorg/Clara/blob/master/README.md)
+for more details on how to use the Clara parser.
+
+
+## Version detection
+
+Catch2 provides a triplet of macros providing the header's version,
+
+* `CATCH_VERSION_MAJOR`
+* `CATCH_VERSION_MINOR`
+* `CATCH_VERSION_PATCH`
+
+these macros expand into a single number, that corresponds to the appropriate
+part of the version. As an example, given single header version v2.3.4,
+the macros would expand into `2`, `3`, and `4` respectively.

+# How to release
+
+When enough changes have accumulated, it is time to release new version of Catch. This document describes the process in doing so, that no steps are forgotten. Note that all referenced scripts can be found in the `tools/scripts/` directory.
+
+## Necessary steps
+
+These steps are necessary and have to be performed before each new release. They serve to make sure that the new release is correct and linked-to from the standard places.
+
+
+### Testing
+
+All of the tests are currently run in our CI setup based on TravisCI and
+AppVeyor. As long as the last commit tested green, the release can
+proceed.
+
+
+### Incrementing version number
+
+Catch uses a variant of [semantic versioning](http://semver.org/), with breaking API changes (and thus major version increments) being very rare. Thus, the release will usually increment the patch version, when it only contains couple of bugfixes, or minor version, when it contains new functionality, or larger changes in implementation of current functionality.
+
+After deciding which part of version number should be incremented, you can use one of the `*Release.py` scripts to perform the required changes to Catch.
+
+This will take care of generating the single include header, updating
+version numbers everywhere and pushing the new version to Wandbox.
+
+
+### Release notes
+
+Once a release is ready, release notes need to be written. They should summarize changes done since last release. For rough idea of expected notes see previous releases. Once written, release notes should be added to `docs/release-notes.md`.
+
+
+### Commit and push update to GitHub
+
+After version number is incremented, single-include header is regenerated and release notes are updated, changes should be committed and pushed to GitHub.
+
+
+### Release on GitHub
+
+After pushing changes to GitHub, GitHub release *needs* to be created.
+Tag version and release title should be same as the new version,
+description should contain the release notes for the current release.
+We also attach the two amalgamated files as "binaries".
+
+Since 2.5.0, the release tag and the "binaries" (amalgamated files) should
+be PGP signed.
+
+#### Signing a tag
+
+To create a signed tag, use `git tag -s <VERSION>`, where `<VERSION>`
+is the version being released, e.g. `git tag -s v2.6.0`.
+
+Use the version name as the short message and the release notes as
+the body (long) message.
+
+#### Signing the amalgamated files
+
+This will create ASCII-armored signatures for the two amalgamated files
+that are uploaded to the GitHub release:
+
+```
+gpg --armor --output extras/catch_amalgamated.hpp.asc --detach-sig extras/catch_amalgamated.hpp
+gpg --armor --output extras/catch_amalgamated.cpp.asc --detach-sig extras/catch_amalgamated.cpp
+```
+
+_GPG does not support signing multiple files in single invocation._

+and by [event listeners](event-listeners.md#top) to perform in-process
+actions under some conditions.
+
+There are currently 21 reporter events in Catch2, split between 4 distinct
+event groups:
+* test running events (10 events)
+* benchmarking (4 events)
+* listings (3 events)
+* miscellaneous (4 events)
+
+## Test running events
+
+Test running events are always paired so that for each `fooStarting` event,
+there is a `fooEnded` event. This means that the 10 test running events
+consist of 5 pairs of events:
+
+* `testRunStarting` and `testRunEnded`,
+* `testCaseStarting` and `testCaseEnded`,
+* `testCasePartialStarting` and `testCasePartialEnded`,
+* `sectionStarting` and `sectionEnded`,
+* `assertionStarting` and `assertionEnded`
+
+### `testRun` events
+
+```cpp
+void testRunStarting( TestRunInfo const& testRunInfo );
+void testRunEnded( TestRunStats const& testRunStats );
+```
+
+The `testRun` events bookend the entire test run. `testRunStarting` is
+emitted before the first test case is executed, and `testRunEnded` is
+emitted after all the test cases have been executed.
+
+### `testCase` events
+
+```cpp
+void testCaseStarting( TestCaseInfo const& testInfo );
+void testCaseEnded( TestCaseStats const& testCaseStats );
+```
+
+The `testCase` events bookend one _full_ run of a specific test case.
+Individual runs through a test case, e.g. due to `SECTION`s or `GENERATE`s,
+are handled by a different event.
+
+
+### `testCasePartial` events
+
+> Introduced in Catch2 3.0.1
+
+```cpp
+void testCasePartialStarting( TestCaseInfo const& testInfo, uint64_t partNumber );
+void testCasePartialEnded(TestCaseStats const& testCaseStats, uint64_t partNumber );
+```
+
+`testCasePartial` events bookend one _partial_ run of a specific test case.
+This means that for any given test case, these events can be emitted
+multiple times, e.g. due to multiple leaf sections.
+
+In regards to nesting with `testCase` events, `testCasePartialStarting`
+will never be emitted before the corresponding `testCaseStarting`, and
+`testCasePartialEnded` will always be emitted before the corresponding
+`testCaseEnded`.
+
+
+### `section` events
+
+```cpp
+void sectionStarting( SectionInfo const& sectionInfo );
+void sectionEnded( SectionStats const& sectionStats );
+```
+
+`section` events are emitted only for active `SECTION`s, that is, sections
+that are entered. Sections that are skipped in this test case run-through
+do not cause events to be emitted.
+
+_Note that test cases always contain one implicit section. The event for
+this section is emitted after the corresponding `testCasePartialStarting`
+event._
+
+
+### `assertion` events
+
+```cpp
+void assertionStarting( AssertionInfo const& assertionInfo );
+void assertionEnded( AssertionStats const& assertionStats );
+```
+
+The `assertionStarting` event is emitted before the expression in the
+assertion is captured or evaluated and `assertionEnded` is emitted
+afterwards. This means that given assertion like `REQUIRE(a + b == c + d)`,
+Catch2 first emits `assertionStarting` event, then `a + b` and `c + d`
+are evaluated, then their results are captured, the comparison is evaluated,
+and then `assertionEnded` event is emitted.
+
+
+## Benchmarking events
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch2 2.9.0.
+
+```cpp
+void benchmarkPreparing( StringRef name ) override;
+void benchmarkStarting( BenchmarkInfo const& benchmarkInfo ) override;
+void benchmarkEnded( BenchmarkStats<> const& benchmarkStats ) override;
+void benchmarkFailed( StringRef error ) override;
+```
+
+Due to the benchmark lifecycle being bit more complicated, the benchmarking
+events have their own category, even though they could be seen as parallel
+to the `assertion*` events. You should expect running a benchmark to
+generate at least 2 of the events above.
+
+To understand the explanation below, you should read the [benchmarking
+documentation](benchmarks.md#top) first.
+
+* `benchmarkPreparing` event is sent after the environmental probe
+finishes, but before the user code is first estimated.
+* `benchmarkStarting` event is sent after the user code is estimated,
+but has not been benchmarked yet.
+* `benchmarkEnded` event is sent after the user code has been benchmarked,
+and contains the benchmarking results.
+* `benchmarkFailed` event is sent if either the estimation or the
+benchmarking itself fails.
+
+
+## Listings events
+
+> Introduced in Catch2 3.0.1.
+
+Listings events are events that correspond to the test binary being
+invoked with `--list-foo` flag.
+
+There are currently 3 listing events, one for reporters, one for tests,
+and one for tags. Note that they are not exclusive to each other.
+
+```cpp
+void listReporters( std::vector<ReporterDescription> const& descriptions );
+void listTests( std::vector<TestCaseHandle> const& tests );
+void listTags( std::vector<TagInfo> const& tagInfos );
+```
+
+
+## Miscellaneous events
+
+```cpp
+void reportInvalidTestSpec( StringRef unmatchedSpec );
+void fatalErrorEncountered( StringRef error );
+void noMatchingTestCases( StringRef unmatchedSpec );
+```
+
+These are one-off events that do not neatly fit into other categories.
+
+`reportInvalidTestSpec` is sent for each [test specification command line
+argument](command-line.md#specifying-which-tests-to-run) that wasn't
+parsed into a valid spec.
+
+`fatalErrorEncountered` is sent when Catch2's POSIX signal handling
+or Windows SE handler is called into with a fatal signal/exception.
+
+`noMatchingTestCases` is sent for each user provided test specification
+that did not match any registered tests.

+# Reporters
+
+Reporters are a customization point for most of Catch2's output, e.g.
+formatting and writing out [assertions (whether passing or failing),
+sections, test cases, benchmarks, and so on](reporter-events.md#top).
+
+Catch2 comes with a bunch of reporters by default (currently 9), and
+you can also write your own reporter. Because multiple reporters can
+be active at the same time, your own reporters do not even have to handle
+all reporter event, just the ones you are interested in, e.g. benchmarks.
+
+
+## Using different reporters
+
+You can see which reporters are available by running the test binary
+with `--list-reporters`. You can then pick one of them with the [`-r`,
+`--reporter` option](command-line.md#choosing-a-reporter-to-use), followed
+by the name of the desired reporter, like so:
+
+```
+--reporter xml
+```
+
+You can also select multiple reporters to be used at the same time.
+In that case you should read the [section on using multiple
+reporters](#multiple-reporters) to avoid any surprises from doing so.
+
+
+<a id="multiple-reporters"></a>
+## Using multiple reporters
+
+> Support for having multiple parallel reporters was [introduced](https://github.com/catchorg/Catch2/pull/2183) in Catch2 3.0.1
+
+Catch2 supports using multiple reporters at the same time while having
+them write into different destinations. The two main uses of this are
+
+* having both human-friendly and machine-parseable (e.g. in JUnit format)
+  output from one run of binary
+* having "partial" reporters that are highly specialized, e.g. having one
+  reporter that writes out benchmark results as markdown tables and does
+  nothing else, while also having standard testing output separately
+
+Specifying multiple reporter looks like this:
+```
+--reporter JUnit::out=result-junit.xml --reporter console::out=-::colour-mode=ansi
+```
+
+This tells Catch2 to use two reporters, `JUnit` reporter that writes
+its machine-readable XML output to file `result-junit.xml`, and the
+`console` reporter that writes its user-friendly output to stdout and
+uses ANSI colour codes for colouring the output.
+
+Using multiple reporters (or one reporter and one-or-more [event
+listeners](event-listeners.md#top)) can have surprisingly complex semantics
+when using customization points provided to reporters by Catch2, namely
+capturing stdout/stderr from test cases.
+
+As long as at least one reporter (or listener) asks Catch2 to capture
+stdout/stderr, captured stdout and stderr will be available to all
+reporters and listeners.
+
+Because this might be surprising to the users, if at least one active
+_reporter_ is non-capturing, then Catch2 tries to roughly emulate
+non-capturing behaviour by printing out the captured stdout/stderr
+just before `testCasePartialEnded` event is sent out to the active
+reporters and listeners. This means that stdout/stderr is no longer
+printed out from tests as it is being written, but instead it is written
+out in batch after each runthrough of a test case is finished.
+
+
+
+## Writing your own reporter
+
+You can also write your own custom reporter and tell Catch2 to use it.
+When writing your reporter, you have two options:
+
+* Derive from `Catch::ReporterBase`. When doing this, you will have
+  to provide handling for all [reporter events](reporter-events.md#top).
+* Derive from one of the provided [utility reporter bases in
+  Catch2](#utility-reporter-bases).
+
+Generally we recommend doing the latter, as it is less work.
+
+Apart from overriding handling of the individual reporter events, reporters
+have access to some extra customization points, described below.
+
+
+### Utility reporter bases
+
+Catch2 currently provides two utility reporter bases:
+
+* `Catch::StreamingReporterBase`
+* `Catch::CumulativeReporterBase`
+
+`StreamingReporterBase` is useful for reporters that can format and write
+out the events as they come in. It provides (usually empty) implementation
+for all reporter events, and if you let it handle the relevant events,
+it also handles storing information about active test run and test case.
+
+`CumulativeReporterBase` is a base for reporters that need to see the whole
+test run, before they can start writing the output, such as the JUnit
+and SonarQube reporters. This post-facto approach requires the assertions
+to be stringified when it is finished, so that the assertion can be written
+out later. Because the stringification can be expensive, and not all
+cumulative reporters need the assertions, this base provides customization
+point to change whether the assertions are saved or not, separate for
+passing and failing assertions.
+
+
+_Generally we recommend that if you override a member function from either
+of the bases, you call into the base's implementation first. This is not
+necessarily in all cases, but it is safer and easier._
+
+
+Writing your own reporter then looks like this:
+
+```cpp
+#include <catch2/reporters/catch_reporter_streaming_base.hpp>
+#include <catch2/catch_test_case_info.hpp>
+#include <catch2/reporters/catch_reporter_registrars.hpp>
+
+#include <iostream>
+
+class PartialReporter : public Catch::StreamingReporterBase {
+public:
+    using StreamingReporterBase::StreamingReporterBase;
+
+    static std::string getDescription() {
+        return "Reporter for testing TestCasePartialStarting/Ended events";
+    }
+
+    void testCasePartialStarting(Catch::TestCaseInfo const& testInfo,
+                                 uint64_t partNumber) override {
+        std::cout << "TestCaseStartingPartial: " << testInfo.name << '#' << partNumber << '\n';
+    }
+
+    void testCasePartialEnded(Catch::TestCaseStats const& testCaseStats,
+                              uint64_t partNumber) override {
+        std::cout << "TestCasePartialEnded: " << testCaseStats.testInfo->name << '#' << partNumber << '\n';
+    }
+};
+
+
+CATCH_REGISTER_REPORTER("partial", PartialReporter)
+```
+
+This create a simple reporter that responds to `testCasePartial*` events,
+and calls itself "partial" reporter, so it can be invoked with
+`--reporter partial` command line flag.
+
+
+### `ReporterPreferences`
+
+Each reporter instance contains instance of `ReporterPreferences`, a type
+that holds flags for the behaviour of Catch2 when this reporter run.
+Currently there are two customization options:
+
+* `shouldRedirectStdOut` - whether the reporter wants to handle
+   writes to stdout/stderr from user code, or not. This is useful for
+   reporters that output machine-parseable output, e.g. the JUnit
+   reporter, or the XML reporter.
+* `shouldReportAllAssertions` - whether the reporter wants to handle
+  `assertionEnded` events for passing assertions as well as failing
+   assertions. Usually reporters do not report successful assertions
+   and don't need them for their output, but sometimes the desired output
+   format includes passing assertions even without the `-s` flag.
+
+
+### Per-reporter configuration
+
+> Per-reporter configuration was introduced in Catch2 3.0.1
+
+Catch2 supports some configuration to happen per reporter. The configuration
+options fall into one of two categories:
+
+* Catch2-recognized options
+* Reporter-specific options
+
+The former is a small set of universal options that Catch2 handles for
+the reporters, e.g. output file or console colour mode. The latter are
+options that the reporters have to handle themselves, but the keys and
+values can be arbitrary strings, as long as they don't contain `::`. This
+allows writing reporters that can be significantly customized at runtime.
+
+Reporter-specific options always have to be prefixed with "X" (large
+letter X).
+
+
+### Other expected functionality of a reporter
+
+When writing a custom reporter, there are few more things that you should
+keep in mind. These are not important for correctness, but they are
+important for the reporter to work _nicely_.
+
+* Catch2 provides a simple verbosity option for users. There are three
+  verbosity levels, "quiet", "normal", and "high", and if it makes sense
+  for reporter's output format, it should respond to these by changing
+  what, and how much, it writes out.
+
+* Catch2 operates with an rng-seed. Knowing what seed a test run had
+  is important if you want to replicate it, so your reporter should
+  report the rng-seed, if at all possible given the target output format.
+
+* Catch2 also operates with test filters, or test specs. If a filter
+  is present, you should also report the filter, if at all possible given
+  the target output format.

+# Explicitly skipping, passing, and failing tests at runtime
+
+## Skipping Test Cases at Runtime
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/2360) in Catch2 3.3.0.
+
+In some situations it may not be possible to meaningfully execute a test case,
+for example when the system under test is missing certain hardware capabilities.
+If the required conditions can only be determined at runtime, it often
+doesn't make sense to consider such a test case as either passed or failed,
+because it simply cannot run at all.
+
+To properly express such scenarios, Catch2 provides a way to explicitly
+_skip_ test cases, using the `SKIP` macro:
+
+```
+SKIP( [streamable expression] )
+```
+
+Example usage:
+
+```c++
+TEST_CASE("copy files between drives") {
+    if(getNumberOfHardDrives() < 2) {
+        SKIP("at least two hard drives required");
+    }
+    // ...
+}
+```
+
+This test case is then reported as _skipped_ instead of _passed_ or _failed_.
+
+The `SKIP` macro behaves similarly to an explicit [`FAIL`](#passing-and-failing-test-cases),
+in that it is the last expression that will be executed:
+
+```c++
+TEST_CASE("my test") {
+    printf("foo");
+    SKIP();
+    printf("bar"); // not printed
+}
+```
+
+However a failed assertion _before_ a `SKIP` still causes the entire
+test case to fail:
+
+```c++
+TEST_CASE("failing test") {
+    CHECK(1 == 2);
+    SKIP();
+}
+```
+
+### Interaction with Sections and Generators
+
+Sections, nested sections as well as specific outputs from [generators](generators.md#top)
+can all be individually skipped, with the rest executing as usual:
+
+```c++
+TEST_CASE("complex test case") {
+  int value = GENERATE(2, 4, 6);
+  SECTION("a") {
+    SECTION("a1") { CHECK(value < 8); }
+    SECTION("a2") {
+      if (value == 4) {
+        SKIP();
+      }
+      CHECK(value % 2 == 0);
+    }
+  }
+}
+```
+
+This test case will report 5 passing assertions; one for each of the three
+values in section `a1`, and then two in section `a2`, from values 2 and 4.
+
+Note that as soon as one section is skipped, the entire test case will
+be reported as _skipped_ (unless there is a failing assertion, in which
+case the test is handled as _failed_ instead).
+
+Note that if all test cases in a run are skipped, Catch2 returns a non-zero
+exit code, same as it does if no test cases have run. This behaviour can
+be overridden using the [--allow-running-no-tests](command-line.md#no-tests-override)
+flag.
+
+### `SKIP` inside generators
+
+You can also use the `SKIP` macro inside generator's constructor to handle
+cases where the generator is empty, but you do not want to fail the test
+case.
+
+
+## Passing and failing test cases
+
+Test cases can also be explicitly passed or failed, without the use of
+assertions, and with a specific message. This can be useful to handle
+complex preconditions/postconditions and give useful error messages
+when they fail.
+
+* `SUCCEED( [streamable expression] )`
+
+`SUCCEED` is morally equivalent with `INFO( [streamable expression] ); REQUIRE( true );`.
+Note that it does not stop further test execution, so it cannot be used
+to guard failing assertions from being executed.
+
+_In practice, `SUCCEED` is usually used as a test placeholder, to avoid
+[failing a test case due to missing assertions](command-line.md#warnings)._
+
+```cpp
+TEST_CASE( "SUCCEED showcase" ) {
+    int I = 1;
+    SUCCEED( "I is " << I );
+    // ... execution continues here ...
+}
+```
+
+* `FAIL( [streamable expression] )`
+
+`FAIL` is morally equivalent with `INFO( [streamable expression] ); REQUIRE( false );`.
+
+_In practice, `FAIL` is usually used to stop executing test that is currently
+known to be broken, but has to be fixed later._
+
+```cpp
+TEST_CASE( "FAIL showcase" ) {
+    FAIL( "This test case causes segfault, which breaks CI." );
+    // ... this will not be executed ...
+}
+```

+
+While Catch fully supports the traditional, xUnit, style of class-based fixtures containing test case methods this is not the preferred style.
+
+Instead Catch provides a powerful mechanism for nesting test case sections within a test case. For a more detailed discussion see the [tutorial](tutorial.md#test-cases-and-sections).
+
+Test cases and sections are very easy to use in practice:
+
+* **TEST_CASE(** _test name_ \[, _tags_ \] **)**
+* **SECTION(** _section name_, \[, _section description_ \] **)**
+
+
+_test name_ and _section name_ are free form, quoted, strings.
+The optional _tags_ argument is a quoted string containing one or more
+tags enclosed in square brackets, and are discussed below.
+_section description_ can be used to provide long form description
+of a section while keeping the _section name_ short for use with the
+[`-c` command line parameter](command-line.md#specify-the-section-to-run).
+
+**The combination of test names and tags must be unique within the Catch2
+executable.**
+
+For examples see the [Tutorial](tutorial.md#top)
+
+## Tags
+
+Tags allow an arbitrary number of additional strings to be associated with a test case. Test cases can be selected (for running, or just for listing) by tag - or even by an expression that combines several tags. At their most basic level they provide a simple way to group several related tests together.
+
+As an example - given the following test cases:
+
+    TEST_CASE( "A", "[widget]" ) { /* ... */ }
+    TEST_CASE( "B", "[widget]" ) { /* ... */ }
+    TEST_CASE( "C", "[gadget]" ) { /* ... */ }
+    TEST_CASE( "D", "[widget][gadget]" ) { /* ... */ }
+
+The tag expression, ```"[widget]"``` selects A, B & D. ```"[gadget]"``` selects C & D. ```"[widget][gadget]"``` selects just D and ```"[widget],[gadget]"``` selects all four test cases.
+
+For more detail on command line selection see [the command line docs](command-line.md#specifying-which-tests-to-run)
+
+Tag names are not case sensitive and can contain any ASCII characters.
+This means that tags `[tag with spaces]` and `[I said "good day"]`
+are both allowed tags and can be filtered on. However, escapes are not
+supported and `[\]]` is not a valid tag.
+
+The same tag can be specified multiple times for a single test case,
+but only one of the instances of identical tags will be kept. Which one
+is kept is functionally random.
+
+
+### Special Tags
+
+All tag names beginning with non-alphanumeric characters are reserved by Catch. Catch defines a number of "special" tags, which have meaning to the test runner itself. These special tags all begin with a symbol character. Following is a list of currently defined special tags and their meanings.
+
+* `[.]` - causes test cases to be skipped from the default list (i.e. when no test cases have been explicitly selected through tag expressions or name wildcards). The hide tag is often combined with another, user, tag (for example `[.][integration]` - so all integration tests are excluded from the default run but can be run by passing `[integration]` on the command line). As a short-cut you can combine these by simply prefixing your user tag with a `.` - e.g. `[.integration]`.
+
+* `[!throws]` - lets Catch know that this test is likely to throw an exception even if successful. This causes the test to be excluded when running with `-e` or `--nothrow`.
+
+* `[!mayfail]` - doesn't fail the test if any given assertion fails (but still reports it). This can be useful to flag a work-in-progress, or a known issue that you don't want to immediately fix but still want to track in your tests.
+
+* `[!shouldfail]` - like `[!mayfail]` but *fails* the test if it *passes*. This can be useful if you want to be notified of accidental, or third-party, fixes.
+
+* `[!nonportable]` - Indicates that behaviour may vary between platforms or compilers.
+
+* `[#<filename>]` - these tags are added to test cases when you run Catch2
+                    with [`-#` or `--filenames-as-tags`](command-line.md#filenames-as-tags).
+
+* `[@<alias>]` - tag aliases all begin with `@` (see below).
+
+* `[!benchmark]` - this test case is actually a benchmark. Currently this only serves to hide the test case by default, to avoid the execution time costs.
+
+
+## Tag aliases
+
+Between tag expressions and wildcarded test names (as well as combinations of the two) quite complex patterns can be constructed to direct which test cases are run. If a complex pattern is used often it is convenient to be able to create an alias for the expression. This can be done, in code, using the following form:
+
+    CATCH_REGISTER_TAG_ALIAS( <alias string>, <tag expression> )
+
+Aliases must begin with the `@` character. An example of a tag alias is:
+
+    CATCH_REGISTER_TAG_ALIAS( "[@nhf]", "[failing]~[.]" )
+
+Now when `[@nhf]` is used on the command line this matches all tests that are tagged `[failing]`, but which are not also hidden.
+
+## BDD-style test cases
+
+In addition to Catch's take on the classic style of test cases, Catch supports an alternative syntax that allow tests to be written as "executable specifications" (one of the early goals of [Behaviour Driven Development](http://dannorth.net/introducing-bdd/)). This set of macros map on to ```TEST_CASE```s and ```SECTION```s, with a little internal support to make them smoother to work with.
+
+* **SCENARIO(** _scenario name_ \[, _tags_ \] **)**
+
+This macro maps onto ```TEST_CASE``` and works in the same way, except that the test case name will be prefixed by "Scenario: "
+
+* **GIVEN(** _something_ **)**
+* **WHEN(** _something_ **)**
+* **THEN(** _something_ **)**
+
+These macros map onto ```SECTION```s except that the section names are the _something_ texts prefixed by
+"given: ", "when: " or "then: " respectively. These macros also map onto the AAA or A<sup>3</sup> test pattern
+(standing either for [Assemble-Activate-Assert](http://wiki.c2.com/?AssembleActivateAssert) or
+[Arrange-Act-Assert](http://wiki.c2.com/?ArrangeActAssert)), and in this context, the macros provide both code
+documentation and reporting of these parts of a test case without the need for extra comments or code to do so.
+
+Semantically, a `GIVEN` clause may have multiple _independent_ `WHEN` clauses within it. This allows a test
+to have, e.g., one set of "given" objects and multiple subtests using those objects in various ways in each
+of the `WHEN` clauses without repeating the initialisation from the `GIVEN` clause. When there are _dependent_
+clauses -- such as a second `WHEN` clause that should only happen _after_ the previous `WHEN` clause has been
+executed and validated -- there are additional macros starting with `AND_`:
+
+* **AND_GIVEN(** _something_ **)**
+* **AND_WHEN(** _something_ **)**
+* **AND_THEN(** _something_ **)**
+
+These are used to chain ```GIVEN```s, ```WHEN```s and ```THEN```s together. The `AND_*` clause is placed
+_inside_ the clause on which it depends. There can be multiple _independent_ clauses that are all _dependent_
+on a single outer clause.
+```cpp
+SCENARIO( "vector can be sized and resized" ) {
+    GIVEN( "An empty vector" ) {
+        auto v = std::vector<std::string>{};
+
+        // Validate assumption of the GIVEN clause
+        THEN( "The size and capacity start at 0" ) {
+            REQUIRE( v.size() == 0 );
+            REQUIRE( v.capacity() == 0 );
+        }
+
+        // Validate one use case for the GIVEN object
+        WHEN( "push_back() is called" ) {
+            v.push_back("hullo");
+
+            THEN( "The size changes" ) {
+                REQUIRE( v.size() == 1 );
+                REQUIRE( v.capacity() >= 1 );
+            }
+        }
+    }
+}
+```
+
+This code will result in two runs through the scenario:
+```
+Scenario : vector can be sized and resized
+  Given  : An empty vector
+  Then   : The size and capacity start at 0
+
+Scenario : vector can be sized and resized
+  Given  : An empty vector
+  When   : push_back() is called
+  Then   : The size changes
+```
+
+See also [runnable example on godbolt](https://godbolt.org/z/eY5a64r99),
+with a more complicated (and failing) example.
+
+> `AND_GIVEN` was [introduced](https://github.com/catchorg/Catch2/issues/1360) in Catch2 2.4.0.
+
+When any of these macros are used the console reporter recognises them and formats the test case header such that the Givens, Whens and Thens are aligned to aid readability.
+
+Other than the additional prefixes and the formatting in the console reporter these macros behave exactly as ```TEST_CASE```s and ```SECTION```s. As such there is nothing enforcing the correct sequencing of these macros - that's up to the programmer!
+
+## Type parametrised test cases
+
+In addition to `TEST_CASE`s, Catch2 also supports test cases parametrised
+by types, in the form of `TEMPLATE_TEST_CASE`,
+`TEMPLATE_PRODUCT_TEST_CASE` and `TEMPLATE_LIST_TEST_CASE`. These macros
+are defined in the `catch_template_test_macros.hpp` header, so compiling
+the code examples below also requires
+`#include <catch2/catch_template_test_macros.hpp>`.
+
+
+* **TEMPLATE_TEST_CASE(** _test name_ , _tags_,  _type1_, _type2_, ..., _typen_ **)**
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1437) in Catch2 2.5.0.
+
+_test name_ and _tag_ are exactly the same as they are in `TEST_CASE`,
+with the difference that the tag string must be provided (however, it
+can be empty). _type1_ through _typen_ is the list of types for which
+this test case should run, and, inside the test code, the current type
+is available as the `TestType` type.
+
+Because of limitations of the C++ preprocessor, if you want to specify
+a type with multiple template parameters, you need to enclose it in
+parentheses, e.g. `std::map<int, std::string>` needs to be passed as
+`(std::map<int, std::string>)`.
+
+Example:
+```cpp
+TEMPLATE_TEST_CASE( "vectors can be sized and resized", "[vector][template]", int, std::string, (std::tuple<int,float>) ) {
+
+    std::vector<TestType> v( 5 );
+
+    REQUIRE( v.size() == 5 );
+    REQUIRE( v.capacity() >= 5 );
+
+    SECTION( "resizing bigger changes size and capacity" ) {
+        v.resize( 10 );
+
+        REQUIRE( v.size() == 10 );
+        REQUIRE( v.capacity() >= 10 );
+    }
+    SECTION( "resizing smaller changes size but not capacity" ) {
+        v.resize( 0 );
+
+        REQUIRE( v.size() == 0 );
+        REQUIRE( v.capacity() >= 5 );
+
+        SECTION( "We can use the 'swap trick' to reset the capacity" ) {
+            std::vector<TestType> empty;
+            empty.swap( v );
+
+            REQUIRE( v.capacity() == 0 );
+        }
+    }
+    SECTION( "reserving smaller does not change size or capacity" ) {
+        v.reserve( 0 );
+
+        REQUIRE( v.size() == 5 );
+        REQUIRE( v.capacity() >= 5 );
+    }
+}
+```
+
+* **TEMPLATE_PRODUCT_TEST_CASE(** _test name_ , _tags_, (_template-type1_, _template-type2_, ..., _template-typen_), (_template-arg1_, _template-arg2_, ..., _template-argm_) **)**
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1468) in Catch2 2.6.0.
+
+_template-type1_ through _template-typen_ is list of template
+types which should be combined with each of _template-arg1_ through
+ _template-argm_, resulting in _n * m_ test cases. Inside the test case,
+the resulting type is available under the name of `TestType`.
+
+To specify more than 1 type as a single _template-type_ or _template-arg_,
+you must enclose the types in an additional set of parentheses, e.g.
+`((int, float), (char, double))` specifies 2 template-args, each
+consisting of 2 concrete types (`int`, `float` and `char`, `double`
+respectively). You can also omit the outer set of parentheses if you
+specify only one type as the full set of either the _template-types_,
+or the _template-args_.
+
+
+Example:
+```cpp
+template< typename T>
+struct Foo {
+    size_t size() {
+        return 0;
+    }
+};
+
+TEMPLATE_PRODUCT_TEST_CASE("A Template product test case", "[template][product]", (std::vector, Foo), (int, float)) {
+    TestType x;
+    REQUIRE(x.size() == 0);
+}
+```
+
+You can also have different arities in the _template-arg_ packs:
+```cpp
+TEMPLATE_PRODUCT_TEST_CASE("Product with differing arities", "[template][product]", std::tuple, (int, (int, double), (int, double, float))) {
+    TestType x;
+    REQUIRE(std::tuple_size<TestType>::value >= 1);
+}
+```
+
+* **TEMPLATE_LIST_TEST_CASE(** _test name_, _tags_, _type list_ **)**
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1627) in Catch2 2.9.0.
+
+_type list_ is a generic list of types on which test case should be instantiated.
+List can be `std::tuple`, `boost::mpl::list`, `boost::mp11::mp_list` or anything with
+`template <typename...>` signature.
+
+This allows you to reuse the _type list_ in multiple test cases.
+
+Example:
+```cpp
+using MyTypes = std::tuple<int, char, float>;
+TEMPLATE_LIST_TEST_CASE("Template test case with test types specified inside std::tuple", "[template][list]", MyTypes)
+{
+    REQUIRE(sizeof(TestType) > 0);
+}
+```
+
+
+## Signature based parametrised test cases
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1609) in Catch2 2.8.0.
+
+In addition to [type parametrised test cases](#type-parametrised-test-cases) Catch2 also supports
+signature base parametrised test cases, in form of `TEMPLATE_TEST_CASE_SIG` and `TEMPLATE_PRODUCT_TEST_CASE_SIG`.
+These test cases have similar syntax like [type parametrised test cases](#type-parametrised-test-cases), with one
+additional positional argument which specifies the signature. These macros are defined in the
+`catch_template_test_macros.hpp` header, so compiling the code examples below also requires
+`#include <catch2/catch_template_test_macros.hpp>`.
+
+### Signature
+Signature has some strict rules for these tests cases to work properly:
+* signature with multiple template parameters e.g. `typename T, size_t S` must have this format in test case declaration
+  `((typename T, size_t S), T, S)`
+* signature with variadic template arguments e.g. `typename T, size_t S, typename...Ts` must have this format in test case declaration
+  `((typename T, size_t S, typename...Ts), T, S, Ts...)`
+* signature with single non type template parameter e.g. `int V` must have this format in test case declaration `((int V), V)`
+* signature with single type template parameter e.g. `typename T` should not be used as it is in fact `TEMPLATE_TEST_CASE`
+
+Currently Catch2 support up to 11 template parameters in signature
+
+### Examples
+
+* **TEMPLATE_TEST_CASE_SIG(** _test name_ , _tags_,  _signature_, _type1_, _type2_, ..., _typen_ **)**
+
+Inside `TEMPLATE_TEST_CASE_SIG` test case you can use the names of template parameters as defined in _signature_.
+
+```cpp
+TEMPLATE_TEST_CASE_SIG("TemplateTestSig: arrays can be created from NTTP arguments", "[vector][template][nttp]",
+  ((typename T, int V), T, V), (int,5), (float,4), (std::string,15), ((std::tuple<int, float>), 6)) {
+
+    std::array<T, V> v;
+    REQUIRE(v.size() > 1);
+}
+```
+
+* **TEMPLATE_PRODUCT_TEST_CASE_SIG(** _test name_ , _tags_, _signature_, (_template-type1_, _template-type2_, ..., _template-typen_), (_template-arg1_, _template-arg2_, ..., _template-argm_) **)**
+
+```cpp
+
+template<typename T, size_t S>
+struct Bar {
+    size_t size() { return S; }
+};
+
+TEMPLATE_PRODUCT_TEST_CASE_SIG("A Template product test case with array signature", "[template][product][nttp]", ((typename T, size_t S), T, S), (std::array, Bar), ((int, 9), (float, 42))) {
+    TestType x;
+    REQUIRE(x.size() > 0);
+}
+```

+
+## Non-Templated test fixtures
+
+Although Catch2 allows you to group tests together as 
+[sections within a test case](test-cases-and-sections.md), it can still 
+be convenient, sometimes, to group them using a more traditional test. 
+Catch2 fully supports this too with 3 different macros for 
+non-templated test fixtures. They are: 
+
+| Macro    | Description |
+|----------|-------------|
+|1. `TEST_CASE_METHOD(className, ...)`| Creates a uniquely named class which inherits from the class specified by `className`. The test function will be a member of this derived class. An instance of the derived class will be created for every partial run of the test case. |
+|2. `METHOD_AS_TEST_CASE(member-function, ...)`| Uses `member-function` as the test function. An instance of the class will be created for each partial run of the test case. |
+|3. `TEST_CASE_PERSISTENT_FIXTURE(className, ...)`| Creates a uniquely named class which inherits from the class specified by `className`. The test function will be a member of this derived class. An instance of the derived class will be created at the start of the test run. That instance will be destroyed once the entire test case has ended. |
+
+### 1. `TEST_CASE_METHOD`
+
+
+You define a `TEST_CASE_METHOD` test fixture as a simple structure:
+
+```c++
+class UniqueTestsFixture {
+  private:
+   static int uniqueID;
+  protected:
+   DBConnection conn;
+  public:
+   UniqueTestsFixture() : conn(DBConnection::createConnection("myDB")) {
+   }
+  protected:
+   int getID() {
+     return ++uniqueID;
+   }
+ };
+
+ int UniqueTestsFixture::uniqueID = 0;
+
+ TEST_CASE_METHOD(UniqueTestsFixture, "Create Employee/No Name", "[create]") {
+   REQUIRE_THROWS(conn.executeSQL("INSERT INTO employee (id, name) VALUES (?, ?)", getID(), ""));
+ }
+ TEST_CASE_METHOD(UniqueTestsFixture, "Create Employee/Normal", "[create]") {
+   REQUIRE(conn.executeSQL("INSERT INTO employee (id, name) VALUES (?, ?)", getID(), "Joe Bloggs"));
+ }
+```
+
+The two test cases here will create uniquely-named derived classes of 
+UniqueTestsFixture and thus can access the `getID()` protected method 
+and `conn` member variables. This ensures that both the test cases 
+are able to create a DBConnection using the same method 
+(DRY principle) and that any ID's created are unique such that the 
+order that tests are executed does not matter. 
+
+### 2. `METHOD_AS_TEST_CASE`
+
+`METHOD_AS_TEST_CASE` lets you register a member function of a class 
+as a Catch2 test case. The class will be separately instantiated 
+for each method registered in this way.
+
+```cpp
+class TestClass {
+    std::string s;
+
+public:
+    TestClass()
+        :s( "hello" )
+    {}
+
+    void testCase() {
+        REQUIRE( s == "hello" );
+    }
+};
+
+
+METHOD_AS_TEST_CASE( TestClass::testCase, "Use class's method as a test case", "[class]" )
+```
+
+This type of fixture is similar to [TEST_CASE_METHOD](#1-test_case_method) except in this 
+case it will directly use the provided class to create an object rather than a derived 
+class.
+
+### 3. `TEST_CASE_PERSISTENT_FIXTURE`
+
+> [Introduced](https://github.com/catchorg/Catch2/pull/2885) in Catch2 3.7.0
+
+`TEST_CASE_PERSISTENT_FIXTURE` behaves in the same way as
+[TEST_CASE_METHOD](#1-test_case_method) except that there will only be
+one instance created throughout the entire run of a test case. To 
+demonstrate this have a look at the following example:
+
+```cpp
+class ClassWithExpensiveSetup {
+public:
+    ClassWithExpensiveSetup() {
+        // expensive construction
+        std::this_thread::sleep_for( std::chrono::seconds( 2 ) );
+    }
+
+    ~ClassWithExpensiveSetup() noexcept {
+        // expensive destruction
+        std::this_thread::sleep_for( std::chrono::seconds( 1 ) );
+    }
+
+    int getInt() const { return 42; }
+};
+
+struct MyFixture {
+    mutable int myInt = 0;
+    ClassWithExpensiveSetup expensive;
+};
+
+TEST_CASE_PERSISTENT_FIXTURE( MyFixture, "Tests with MyFixture" ) {
+
+    const int val = myInt++;
+
+    SECTION( "First partial run" ) {
+        const auto otherValue = expensive.getInt();
+        REQUIRE( val == 0 );
+        REQUIRE( otherValue == 42 );
+    }
+
+    SECTION( "Second partial run" ) { REQUIRE( val == 1 ); }
+}
+```
+
+This example demonstates two possible use-cases of this fixture type:
+1. Improve test run times by reducing the amount of expensive and 
+redundant setup and tear-down required.
+2. Reusing results from the previous partial run, in the current
+partial run.
+
+This test case will be executed twice as there are two leaf sections.
+On the first run `val` will be `0` and on the second run `val` will be 
+`1`. This demonstrates that we were able to use the results of the
+previous partial run in subsequent partial runs.
+
+Additionally, we are simulating an expensive object using 
+`std::this_thread::sleep_for`, but real world use-cases could be:
+1. Creating a D3D12/Vulkan device
+2. Connecting to a database
+3. Loading a file.
+
+The fixture object (`MyFixture`) will be constructed just before the
+test case begins, and it will be destroyed just after the test case 
+ends. Therefore, this expensive object will only be created and 
+destroyed once during the execution of this test case. If we had used 
+`TEST_CASE_METHOD`, `MyFixture` would have been created and destroyed 
+twice during the execution of this test case.
+
+NOTE: The member function which runs the test case is `const`. Therefore 
+if you want to mutate any member of the fixture it must be marked as
+`mutable` as shown in this example. This is to make it clear that
+the initial state of the fixture is intended to mutate during the
+execution of the test case.
+
+## Templated test fixtures
+
+Catch2 also provides `TEMPLATE_TEST_CASE_METHOD` and
+`TEMPLATE_PRODUCT_TEST_CASE_METHOD` that can be used together
+with templated fixtures and templated template fixtures to perform
+tests for multiple different types. Unlike `TEST_CASE_METHOD`,
+`TEMPLATE_TEST_CASE_METHOD` and `TEMPLATE_PRODUCT_TEST_CASE_METHOD` do
+require the tag specification to be non-empty, as it is followed by
+further macro arguments.
+
+Also note that, because of limitations of the C++ preprocessor, if you
+want to specify a type with multiple template parameters, you need to
+enclose it in parentheses, e.g. `std::map<int, std::string>` needs to be
+passed as `(std::map<int, std::string>)`.
+In the case of `TEMPLATE_PRODUCT_TEST_CASE_METHOD`, if a member of the
+type list should consist of more than single type, it needs to be enclosed
+in another pair of parentheses, e.g. `(std::map, std::pair)` and
+`((int, float), (char, double))`.
+
+Example:
+```cpp
+template< typename T >
+struct Template_Fixture {
+    Template_Fixture(): m_a(1) {}
+
+    T m_a;
+};
+
+TEMPLATE_TEST_CASE_METHOD(Template_Fixture,
+                          "A TEMPLATE_TEST_CASE_METHOD based test run that succeeds",
+                          "[class][template]",
+                          int, float, double) {
+    REQUIRE( Template_Fixture<TestType>::m_a == 1 );
+}
+
+template<typename T>
+struct Template_Template_Fixture {
+    Template_Template_Fixture() {}
+
+    T m_a;
+};
+
+template<typename T>
+struct Foo_class {
+    size_t size() {
+        return 0;
+    }
+};
+
+TEMPLATE_PRODUCT_TEST_CASE_METHOD(Template_Template_Fixture,
+                                  "A TEMPLATE_PRODUCT_TEST_CASE_METHOD based test succeeds",
+                                  "[class][template]",
+                                  (Foo_class, std::vector),
+                                  int) {
+    REQUIRE( Template_Template_Fixture<TestType>::m_a.size() == 0 );
+}
+```
+
+_While there is an upper limit on the number of types you can specify
+in single `TEMPLATE_TEST_CASE_METHOD` or `TEMPLATE_PRODUCT_TEST_CASE_METHOD`,
+the limit is very high and should not be encountered in practice._
+
+## Signature-based parameterised test fixtures
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1609) in Catch2 2.8.0.
+
+Catch2 also provides `TEMPLATE_TEST_CASE_METHOD_SIG` and `TEMPLATE_PRODUCT_TEST_CASE_METHOD_SIG` to support
+fixtures using non-type template parameters. These test cases work similar to `TEMPLATE_TEST_CASE_METHOD` and `TEMPLATE_PRODUCT_TEST_CASE_METHOD`,
+with additional positional argument for [signature](test-cases-and-sections.md#signature-based-parametrised-test-cases).
+
+Example:
+```cpp
+template <int V>
+struct Nttp_Fixture{
+    int value = V;
+};
+
+TEMPLATE_TEST_CASE_METHOD_SIG(
+    Nttp_Fixture,
+    "A TEMPLATE_TEST_CASE_METHOD_SIG based test run that succeeds",
+    "[class][template][nttp]",
+    ((int V), V),
+    1, 3, 6) {
+    REQUIRE(Nttp_Fixture<V>::value > 0);
+}
+
+template<typename T>
+struct Template_Fixture_2 {
+    Template_Fixture_2() {}
+
+    T m_a;
+};
+
+template< typename T, size_t V>
+struct Template_Foo_2 {
+    size_t size() { return V; }
+};
+
+TEMPLATE_PRODUCT_TEST_CASE_METHOD_SIG(
+    Template_Fixture_2,
+    "A TEMPLATE_PRODUCT_TEST_CASE_METHOD_SIG based test run that succeeds",
+    "[class][template][product][nttp]",
+    ((typename T, size_t S), T, S),
+    (std::array, Template_Foo_2),
+    ((int,2), (float,6))) {
+    REQUIRE(Template_Fixture_2<TestType>{}.m_a.size() >= 2);
+}
+```
+
+## Template fixtures with types specified in template type lists
+
+Catch2 also provides `TEMPLATE_LIST_TEST_CASE_METHOD` to support template fixtures with types specified in
+template type lists like `std::tuple`, `boost::mpl::list` or `boost::mp11::mp_list`. This test case works the same as `TEMPLATE_TEST_CASE_METHOD`,
+only difference is the source of types. This allows you to reuse the template type list in multiple test cases.
+
+Example:
+```cpp
+using MyTypes = std::tuple<int, char, double>;
+TEMPLATE_LIST_TEST_CASE_METHOD(Template_Fixture,
+                               "Template test case method with test types specified inside std::tuple",
+                               "[class][template][list]",
+                               MyTypes) {
+    REQUIRE( Template_Fixture<TestType>::m_a == 1 );
+}
+```

+# String conversions
+
+**Contents**<br>
+[operator << overload for std::ostream](#operator--overload-for-stdostream)<br>
+[Catch::StringMaker specialisation](#catchstringmaker-specialisation)<br>
+[Catch::is_range specialisation](#catchis_range-specialisation)<br>
+[Exceptions](#exceptions)<br>
+[Enums](#enums)<br>
+[Floating point precision](#floating-point-precision)<br>
+
+
+Catch needs to be able to convert types you use in assertions and logging expressions into strings (for logging and reporting purposes).
+Most built-in or std types are supported out of the box but there are two ways that you can tell Catch how to convert your own types (or other, third-party types) into strings.
+
+## operator << overload for std::ostream
+
+This is the standard way of providing string conversions in C++ - and the chances are you may already provide this for your own purposes. If you're not familiar with this idiom it involves writing a free function of the form:
+
+```cpp
+std::ostream& operator << ( std::ostream& os, T const& value ) {
+    os << convertMyTypeToString( value );
+    return os;
+}
+```
+
+(where ```T``` is your type and ```convertMyTypeToString``` is where you'll write whatever code is necessary to make your type printable - it doesn't have to be in another function).
+
+You should put this function in the same namespace as your type, or the global namespace, and have it declared before including Catch's header.
+
+## Catch::StringMaker specialisation
+If you don't want to provide an ```operator <<``` overload, or you want to convert your type differently for testing purposes, you can provide a specialization for `Catch::StringMaker<T>`:
+
+```cpp
+namespace Catch {
+    template<>
+    struct StringMaker<T> {
+        static std::string convert( T const& value ) {
+            return convertMyTypeToString( value );
+        }
+    };
+}
+```
+
+## Catch::is_range specialisation
+As a fallback, Catch attempts to detect if the type can be iterated
+(`begin(T)` and `end(T)` are valid) and if it can be, it is stringified
+as a range. For certain types this can lead to infinite recursion, so
+it can be disabled by specializing `Catch::is_range` like so:
+
+```cpp
+namespace Catch {
+    template<>
+    struct is_range<T> {
+        static const bool value = false;
+    };
+}
+
+```
+
+
+## Exceptions
+
+By default all exceptions deriving from `std::exception` will be translated to strings by calling the `what()` method. For exception types that do not derive from `std::exception` - or if `what()` does not return a suitable string - use `CATCH_TRANSLATE_EXCEPTION`. This defines a function that takes your exception type, by reference, and returns a string. It can appear anywhere in the code - it doesn't have to be in the same translation unit. For example:
+
+```cpp
+CATCH_TRANSLATE_EXCEPTION( MyType const& ex ) {
+    return ex.message();
+}
+```
+
+## Enums
+
+> Introduced in Catch2 2.8.0.
+
+Enums that already have a `<<` overload for `std::ostream` will convert to strings as expected.
+If you only need to convert enums to strings for test reporting purposes you can provide a `StringMaker` specialisations as any other type.
+However, as a convenience, Catch provides the `REGISTER_ENUM` helper macro that will generate the `StringMaker` specialisation for you with minimal code.
+Simply provide it the (qualified) enum name, followed by all the enum values, and you're done!
+
+E.g.
+
+```cpp
+enum class Fruits { Banana, Apple, Mango };
+
+CATCH_REGISTER_ENUM( Fruits, Fruits::Banana, Fruits::Apple, Fruits::Mango )
+
+TEST_CASE() {
+    REQUIRE( Fruits::Mango == Fruits::Apple );
+}
+```
+
+... or if the enum is in a namespace:
+```cpp
+namespace Bikeshed {
+    enum class Colours { Red, Green, Blue };
+}
+
+// Important!: This macro must appear at top level scope - not inside a namespace
+// You can fully qualify the names, or use a using if you prefer
+CATCH_REGISTER_ENUM( Bikeshed::Colours,
+    Bikeshed::Colours::Red,
+    Bikeshed::Colours::Green,
+    Bikeshed::Colours::Blue )
+
+TEST_CASE() {
+    REQUIRE( Bikeshed::Colours::Red == Bikeshed::Colours::Blue );
+}
+```
+
+## Floating point precision
+
+> [Introduced](https://github.com/catchorg/Catch2/issues/1614) in Catch2 2.8.0.
+
+Catch provides a built-in `StringMaker` specialization for both `float`
+and `double`. By default, it uses what we think is a reasonable precision,
+but you can customize it by modifying the `precision` static variable
+inside the `StringMaker` specialization, like so:
+
+```cpp
+        Catch::StringMaker<float>::precision = 15;
+        const float testFloat1 = 1.12345678901234567899f;
+        const float testFloat2 = 1.12345678991234567899f;
+        REQUIRE(testFloat1 == testFloat2);
+```
+
+This assertion will fail and print out the `testFloat1` and `testFloat2`
+to 15 decimal places.

+
+## Getting Catch2
+
+Ideally you should be using Catch2 through its [CMake integration](cmake-integration.md#top).
+Catch2 also provides pkg-config files and two file (header + cpp)
+distribution, but this documentation will assume you are using CMake. If
+you are using the two file distribution instead, remember to replace
+the included header with `catch_amalgamated.hpp` ([step by step instructions](migrate-v2-to-v3.md#how-to-migrate-projects-from-v2-to-v3)).
+
+
+## Writing tests
+
+Let's start with a really simple example ([code](../examples/010-TestCase.cpp)). Say you have written a function to calculate factorials and now you want to test it (let's leave aside TDD for now).
+
+```c++
+unsigned int Factorial( unsigned int number ) {
+    return number <= 1 ? number : Factorial(number-1)*number;
+}
+```
+
+```c++
+#include <catch2/catch_test_macros.hpp>
+
+unsigned int Factorial( unsigned int number ) {
+    return number <= 1 ? number : Factorial(number-1)*number;
+}
+
+TEST_CASE( "Factorials are computed", "[factorial]" ) {
+    REQUIRE( Factorial(1) == 1 );
+    REQUIRE( Factorial(2) == 2 );
+    REQUIRE( Factorial(3) == 6 );
+    REQUIRE( Factorial(10) == 3628800 );
+}
+```
+
+This will compile to a complete executable which responds to [command line arguments](command-line.md#top). If you just run it with no arguments it will execute all test cases (in this case there is just one), report any failures, report a summary of how many tests passed and failed and return the number of failed tests (useful for if you just want a yes/ no answer to: "did it work").
+
+Anyway, as the tests above as written will pass, but there is a bug.
+The problem is that `Factorial(0)` should return 1 (due to [its
+definition](https://en.wikipedia.org/wiki/Factorial#Factorial_of_zero)).
+Let's add that as an assertion to the test case:
+
+```c++
+TEST_CASE( "Factorials are computed", "[factorial]" ) {
+    REQUIRE( Factorial(0) == 1 );
+    REQUIRE( Factorial(1) == 1 );
+    REQUIRE( Factorial(2) == 2 );
+    REQUIRE( Factorial(3) == 6 );
+    REQUIRE( Factorial(10) == 3628800 );
+}
+```
+
+After another compile & run cycle, we will see a test failure. The output
+will look something like:
+
+```
+Example.cpp:9: FAILED:
+  REQUIRE( Factorial(0) == 1 )
+with expansion:
+  0 == 1
+```
+
+Note that the output contains both the original expression,
+`REQUIRE( Factorial(0) == 1 )` and the actual value returned by the call
+to the `Factorial` function: `0`.
+
+We can fix this bug by slightly modifying the `Factorial` function to:
+```c++
+unsigned int Factorial( unsigned int number ) {
+  return number > 1 ? Factorial(number-1)*number : 1;
+}
+```
+
+
+### What did we do here?
+
+Although this was a simple test it's been enough to demonstrate a few
+things about how Catch2 is used. Let's take a moment to consider those
+before we move on.
+
+* We introduce test cases with the `TEST_CASE` macro. This macro takes
+  one or two string arguments - a free form test name and, optionally,
+  one or more tags (for more see [Test cases and Sections](#test-cases-and-sections)).
+* The test automatically self-registers with the test runner, and user
+  does not have do anything more to ensure that it is picked up by the test
+  framework. _Note that you can run specific test, or set of tests,
+  through the [command line](command-line.md#top)._
+* The individual test assertions are written using the `REQUIRE` macro.
+  It accepts a boolean expression, and uses expression templates to
+  internally decompose it, so that it can be individually stringified
+  on test failure.
+
+On the last point, note that there are more testing macros available,
+because not all useful checks can be expressed as a simple boolean
+expression. As an example, checking that an expression throws an exception
+is done with the `REQUIRE_THROWS` macro. More on that later.
+
+
+## Test cases and sections
+
+Like most test frameworks, Catch2 supports a class-based fixture mechanism,
+where individual tests are methods on class and setup/teardown can be
+done in constructor/destructor of the type.
+
+However, their use in Catch2 is rare, because idiomatic Catch2 tests
+instead use _sections_ to share setup and teardown code between test code.
+This is best explained through an example ([code](../examples/100-Fix-Section.cpp)):
+
+```c++
+TEST_CASE( "vectors can be sized and resized", "[vector]" ) {
+    // This setup will be done 4 times in total, once for each section
+    std::vector<int> v( 5 );
+
+    REQUIRE( v.size() == 5 );
+    REQUIRE( v.capacity() >= 5 );
+
+    SECTION( "resizing bigger changes size and capacity" ) {
+        v.resize( 10 );
+
+        REQUIRE( v.size() == 10 );
+        REQUIRE( v.capacity() >= 10 );
+    }
+    SECTION( "resizing smaller changes size but not capacity" ) {
+        v.resize( 0 );
+
+        REQUIRE( v.size() == 0 );
+        REQUIRE( v.capacity() >= 5 );
+    }
+    SECTION( "reserving bigger changes capacity but not size" ) {
+        v.reserve( 10 );
+
+        REQUIRE( v.size() == 5 );
+        REQUIRE( v.capacity() >= 10 );
+    }
+    SECTION( "reserving smaller does not change size or capacity" ) {
+        v.reserve( 0 );
+
+        REQUIRE( v.size() == 5 );
+        REQUIRE( v.capacity() >= 5 );
+    }
+}
+```
+
+For each `SECTION` the `TEST_CASE` is **executed from the start**. This means
+that each section is entered with a freshly constructed vector `v`, that
+we know has size 5 and capacity at least 5, because the two assertions
+are also checked before the section is entered. This behaviour may not be
+ideal for tests where setup is expensive. Each run through a test case will
+execute one, and only one, leaf section.
+
+Section can also be nested, in which case the parent section can be
+entered multiple times, once for each leaf section. Nested sections are
+most useful when you have multiple tests that share part of the set up.
+To continue on the vector example above, you could add a check that
+`std::vector::reserve` does not remove unused excess capacity, like this:
+
+```cpp
+    SECTION( "reserving bigger changes capacity but not size" ) {
+        v.reserve( 10 );
+
+        REQUIRE( v.size() == 5 );
+        REQUIRE( v.capacity() >= 10 );
+        SECTION( "reserving down unused capacity does not change capacity" ) {
+            v.reserve( 7 );
+            REQUIRE( v.size() == 5 );
+            REQUIRE( v.capacity() >= 10 );
+        }
+    }
+```
+
+Another way to look at sections is that they are a way to define a tree
+of paths through the test. Each section represents a node, and the final
+tree is walked in depth-first manner, with each path only visiting only
+one leaf node.
+
+There is no practical limit on nesting sections, as long as your compiler
+can handle them, but keep in mind that overly nested sections can become
+unreadable. From experience, having section nest more than 3 levels is
+usually very hard to follow and not worth the removed duplication.
+
+
+## BDD style testing
+
+Catch2 also provides some basic support for BDD-style testing. There are
+macro aliases for `TEST_CASE` and `SECTIONS` that you can use so that
+the resulting tests read as BDD spec. `SCENARIO` acts as a `TEST_CASE`
+with "Scenario: " name prefix. Then there are `GIVEN`, `WHEN`, `THEN`
+(and their variants with `AND_` prefix), which act as a `SECTION`,
+similarly prefixed with the macro name.
+
+For more details on the macros look at the [test cases and
+sections](test-cases-and-sections.md#top) part of the reference docs,
+or at the [vector example done with BDD macros](../examples/120-Bdd-ScenarioGivenWhenThen.cpp).
+
+
+## Data and Type driven tests
+
+Test cases in Catch2 can also be driven by types, input data, or both
+at the same time.
+
+For more details look into the Catch2 reference, either at the
+[type parametrized test cases](test-cases-and-sections.md#type-parametrised-test-cases),
+or [data generators](generators.md#top).
+
+
+## Next steps
+
+This page is a brief introduction to get you up and running with Catch2,
+and to show the basic features of Catch2. The features mentioned here
+can get you quite far, but there are many more. However, you can read
+about these as you go, in the ever-growing [reference section](Readme.md#top)
+of the documentation.

+# Best practices and other tips on using Catch2
+
+## Running tests
+
+Your tests should be run in a manner roughly equivalent with:
+
+```
+./tests --order rand --warn NoAssertions
+```
+
+Notice that all the tests are run in a large batch, their relative order
+is randomized, and that you ask Catch2 to fail test whose leaf-path
+does not contain an assertion.
+
+The reason I recommend running all your tests in the same process is that
+this exposes your tests to interference from their runs. This can be both
+positive interference, where the changes in global state from previous
+test allow later tests to pass, but also negative interference, where
+changes in global state from previous test causes later tests to fail.
+
+In my experience, interference, especially destructive interference,
+usually comes from errors in the code under test, rather than the tests
+themselves. This means that by allowing interference to happen, our tests
+can find these issues. Obviously, to shake out interference coming from
+different orderings of tests, the test order also need to be shuffled
+between runs.
+
+However, running all tests in a single batch eventually becomes impractical
+as they will take too long to run, and you will want to run your tests
+in parallel.
+
+
+<a id="parallel-tests"></a>
+## Running tests in parallel
+
+There are multiple ways of running tests in parallel, with various level
+of structure. If you are using CMake and CTest, then we provide a helper
+function [`catch_discover_tests`](cmake-integration.md#automatic-test-registration)
+that registers each Catch2 `TEST_CASE` as a single CTest test, which
+is then run in a separate process. This is an easy way to set up parallel
+tests if you are already using CMake & CTest to run your tests, but you
+will lose the advantage of running tests in batches.
+
+
+Catch2 also supports [splitting tests in a binary into multiple
+shards](command-line.md#test-sharding). This can be used by any test
+runner to run batches of tests in parallel. Do note that when selecting
+on the number of shards, you should have more shards than there are cores,
+to avoid issues with long-running tests getting accidentally grouped in
+the same shard, and causing long-tailed execution time.
+
+**Note that naively composing sharding and random ordering of tests will break.**
+
+Invoking Catch2 test executable like this
+
+```text
+./tests --order rand --shard-index 0 --shard-count 3
+./tests --order rand --shard-index 1 --shard-count 3
+./tests --order rand --shard-index 2 --shard-count 3
+```
+
+does not guarantee covering all tests inside the executable, because
+each invocation will have its own random seed, thus it will have its own
+random order of tests and thus the partitioning of tests into shards will
+be different as well.
+
+To do this properly, you need the individual shards to share the random
+seed, e.g.
+```text
+./tests --order rand --shard-index 0 --shard-count 3 --rng-seed 0xBEEF
+./tests --order rand --shard-index 1 --shard-count 3 --rng-seed 0xBEEF
+./tests --order rand --shard-index 2 --shard-count 3 --rng-seed 0xBEEF
+```
+
+Catch2 actually provides a helper to automatically register multiple shards
+as CTest tests, with shared random seed that changes each CTest invocation.
+For details look at the documentation of
+[`CatchShardTests.cmake` CMake script](cmake-integration.md#catchshardtestscmake).
+
+
+## Organizing tests into binaries
+
+Both overly large and overly small test binaries can cause issues. Overly
+large test binaries have to be recompiled and relinked often, and the
+link times are usually also long. Overly small test binaries in turn pay
+significant overhead from linking against Catch2 more often per compiled
+test case, and also make it hard/impossible to run tests in batches.
+
+Because there is no hard and fast rule for the right size of a test binary,
+I recommend having 1:1 correspondence between libraries in project and test
+binaries. (At least if it is possible, in some cases it is not.) Having
+a test binary for each library in project keeps related tests together,
+and makes tests easy to navigate by reflecting the project's organizational
+structure.

+# Why do we need yet another C++ test framework?
+
+Good question. For C++ there are quite a number of established frameworks,
+including (but not limited to),
+[Google Test](http://code.google.com/p/googletest/),
+[Boost.Test](http://www.boost.org/doc/libs/1_49_0/libs/test/doc/html/index.html),
+[CppUnit](http://sourceforge.net/apps/mediawiki/cppunit/index.php?title=Main_Page),
+[Cute](http://www.cute-test.com), and
+[many, many more](http://en.wikipedia.org/wiki/List_of_unit_testing_frameworks#C.2B.2B).
+
+So what does Catch2 bring to the party that differentiates it from these? Apart from the catchy name, of course.
+
+
+## Key Features
+
+* Quick and easy to get started. Just download two files, add them into your project and you're away.
+* No external dependencies. As long as you can compile C++14 and have the C++ standard library available.
+* Write test cases as, self-registering, functions (or methods, if you prefer).
+* Divide test cases into sections, each of which is run in isolation (eliminates the need for fixtures).
+* Use BDD-style Given-When-Then sections as well as traditional unit test cases.
+* Only one core assertion macro for comparisons. Standard C/C++ operators are used for the comparison - yet the full expression is decomposed and lhs and rhs values are logged.
+* Tests are named using free-form strings - no more couching names in legal identifiers.
+
+
+## Other core features
+
+* Tests can be tagged for easily running ad-hoc groups of tests.
+* Failures can (optionally) break into the debugger on common platforms.
+* Output is through modular reporter objects. Basic textual and XML reporters are included. Custom reporters can easily be added.
+* JUnit xml output is supported for integration with third-party tools, such as CI servers.
+* A default main() function is provided, but you can supply your own for complete control (e.g. integration into your own test runner GUI).
+* A command line parser is provided and can still be used if you choose to provide your own main() function.
+* Alternative assertion macro(s) report failures but don't abort the test case
+* Good set of facilities for floating point comparisons (`Catch::Approx` and full set of matchers)
+* Internal and friendly macros are isolated so name clashes can be managed
+* Data generators (data driven test support)
+* Hamcrest-style Matchers for testing complex properties
+* Microbenchmarking support
+
+
+## Who else is using Catch2?
+
+A whole lot of people. According to [the 2022 JetBrains C++ ecosystem survey](https://www.jetbrains.com/lp/devecosystem-2022/cpp/#Which-unit-testing-frameworks-do-you-regularly-use),
+about 12% of C++ programmers use Catch2 for unit testing, making it the
+second most popular unit testing framework.
+
+You can also take a look at the (incomplete) list of [open source projects](opensource-users.md#top)
+or the (very incomplete) list of [commercial users of Catch2](commercial-users.md#top)
+for some idea on who else also uses Catch2.
+

+
+See the [tutorial](tutorial.md#top) to get more of a taste of using
+Catch2 in practice.
