## FSFW Testing
|
||||
This repository contains testing and unit testing components.
|
||||
|
||||
[Catch2](https://github.com/catchorg/Catch2) has been used as a framework,
|
||||
and these unit tests can only be run on a linux host machine.
|
||||
The makefile with default settings creates the unit test binary which can be
|
||||
run in the terminal or in eclipse.
|
||||
This folder contains testing and unit testing components.
|
||||
|
||||
### Instructions
|
||||
|
||||
To run the fsfw unittests in the project, perform following steps:
|
||||
The easiest way to run the unittest contained in this folder is to follow
|
||||
the steps in the [test repository](https://egit.irs.uni-stuttgart.de/fsfw/fsfw_tests).
|
||||
This is recommended even if the goal is to set up a custom test repository to have
|
||||
a starting point.
|
||||
|
||||
1. Copy the testcfg folder the project root (folder containing the FSFW).
|
||||
2. There is a makefile inside the testcfg folder which can be used to have
|
||||
a starting point to compile the unit tests. Copy that Makefile to the project
|
||||
root
|
||||
3. Create a folder named catch2 (can have other name which requires Makefile
|
||||
adaption) and copy the Catch2 header files there (NOTE: CMake support
|
||||
not enabled yet!)
|
||||
To set up a custom test repository or project, following steps can be performed:
|
||||
|
||||
1. Copy the user folder content into the project root.
|
||||
2. Clone [Catch2](https://github.com/catchorg/Catch2) in the project root.
|
||||
3. Use the `CMakeLists.txt` as a starting point to add tests and build the test
|
||||
executable.
|
||||
|
||||
### Eclipse CDT settings
|
||||
|
||||
The default eclipse terminal has issues displaying the colors used
|
||||
when running the unit test binary by catch2. To fix this issue,
|
||||
install the ANSI Escape In Console package from the eclipse marketplace.
|
||||
|
||||
### GCOV integration
|
||||
|
||||
GCOV has been integrated as a code coverage tool.
|
||||
It can be enabled by adding `GCOV=1` to the build process as an additional argument.
|
||||
Coverage data will be provided in form of .gcno and .gcda files.
|
||||
These can be displayed in eclipse by looking
|
||||
for a .gcno or .gcda file in the \_obj folder, double-clicking it
|
||||
and picking the right source-binary. This will generate
|
||||
information about which lines of a file have run, provided it is open in
|
||||
eclipse.
|
||||
|
||||
### LCOV integration
|
||||
|
||||
The files generated by GCOV can also be processed by the tool LCOV.
|
||||
On ubuntu, the tool can be installed with the following command:
|
||||
|
||||
```sh
|
||||
sudo apt-get install lcov
|
||||
````
|
||||
|
||||
After that, the tool can be run by building the unit tests with `GCOV=1`,
|
||||
running them at least one time and then executing the `lcov.sh` script.
|
||||
|
||||
### Adding unit tests
|
||||
|
||||
The catch unit tests are located in unittest/testfw. To add new unit tests,
|
||||
add them to the UnitTestCatch.cpp file or add a new source file which
|
||||
includes catch.hpp.
|
||||
|
||||
For writing basics tests, the [assertion documentation](https://github.com/catchorg/Catch2/blob/master/docs/assertions.md#top)
|
||||
or the existing examples are a good guideliens.
|
||||
For more advanced tests, refer to the [catch2 documentation](https://github.com/catchorg/Catch2/blob/master/docs/Readme.md#top).
