| # 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") # |

| # 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 # |
