TCM provides a single function for testing using Catch2.

tcm_tests (
        [NAME <name>] 
        FILES <file>...
        [LIBRARIES <target> ...]
)

If no NAME is provided, then sources files are added to default target ${PROJECT_NAME}_Tests. Otherwise, a target with provided name is created.

Every target is linked with Catch2::Catch2WithMain, so no need to provide a main function. Multiple calls with the same target will just add sources files to the target.

Benchmark target can also be linked with LIBRARIES targets

Example

tcm_tests(FILES test_1.cpp test_2.cpp) # Added to default target `tcm_tests`

tcm_tests(NAME my_test FILES test_1.cpp test_2.cpp) # Added to target `my_target`

If you wish to override Catch2, do the following once before calling ${PROJECT_NAME}_Tests:

tcm_setup_test(CATCH2_VERSION "vX.X.X")
