\section inside_tests_add_units Adding unit tests
If you want to test a specific function or set of functions, you need
-a unit test. Edit
-<project/directory>/tools/cmake/UnitTesting.cmake to add your
-source file to the TEST_CFILES list, and add the corresponding unit
-file to the TEST_UNITS list. For example, if your file is toto.c,
-your unit file will be toto_unit.c. The full path to your file must be
-provided, but the unit file will always be in src/ directly.
-
-If you want to create unit tests in the file src/xbt/toto.c, your
-changes should look similar to:
+a unit test. Edit the file tools/cmake/UnitTesting.cmake to
+add your source file to the FILES_CONTAINING_UNITTESTS list. For
+example, if you want to create unit tests in the file src/xbt/plouf.c,
+your changes should look like that:
