|
# Usage #
|
||
|
|
# 1. make sure this module is in the path or add this otherwise: #
|
||
|
|
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
|
||
|
|
# 2. make sure that you've enabled testing option for the project by the call: #
|
||
|
|
# enable_testing() #
|
||
|
|
# 3. add the lines to the script for testing target (sample CMakeLists.txt): #
|
||
|
|
# project(testing_target) #
|
||
|
|
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
|
||
|
|
# enable_testing() #
|
||
|
|
# #
|
||
|
|
# find_path(CATCH_INCLUDE_DIR "catch.hpp") #
|
||
|
|
# include_directories(${INCLUDE_DIRECTORIES} ${CATCH_INCLUDE_DIR}) #
|
||
|
|
# #
|
||
|
|
# file(GLOB SOURCE_FILES "*.cpp") #
|
||
|
|
# add_executable(${PROJECT_NAME} ${SOURCE_FILES}) #
|
||
|
|
# #
|
||
|
|
# include(ParseAndAddCatchTests) #
|
||
|
|
# ParseAndAddCatchTests(${PROJECT_NAME}) #
|
||
|
|
# #
|
||
|
|
# The following variables affect the behavior of the script: #
|
||
|
|
# #
|
||
|
|
# PARSE_CATCH_TESTS_VERBOSE (Default OFF) #
|
||
|
|
# -- enables debug messages #
|
||
|
|
# PARSE_CATCH_TESTS_NO_HIDDEN_TESTS (Default OFF) #
|
||
|
|
# -- excludes tests marked with [!hide], [.] or [.foo] tags #
|
||
|
|
# PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME (Default ON) #
|
||
|
|
# -- adds fixture class name to the test name #
|
||
|
|
# PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME (Default ON) #
|
||
|
|
# -- adds cmake target name to the test name #
|
||
|
|
# PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS (Default OFF) #
|
||
|
|
# -- causes CMake to rerun when file with tests changes so that new tests will be discovered #
|
||
|
|
# #
|
||
|
|
# One can also set (locally) the optional variable OptionalCatchTestLauncher to precise the way #
|
||
|
|
# a test should be run. For instance to use test MPI, one can write #
|
||
|
|
# set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC}) #
|
||
|
|
# just before calling this ParseAndAddCatchTests function #
|
||
|
|
# #
|
||
|
|
# The AdditionalCatchParameters optional variable can be used to pass extra argument to the test #
|
||
|
|
# command. For example, to include successful tests in the output, one can write #
|
||
|
|
# set(AdditionalCatchParameters --success) #
|
||
|
|
# #
|
||
|
|
# After the script, the ParseAndAddCatchTests_TESTS property for the target, and for each source #
|
||
|
|
# file in the target is set, and contains the list of the tests extracted from that target, or #
|
||
|
|
# from that file. This is useful, for example to add further labels or properties to the tests. #
