This recipe was inspired by the work of Craig Scott, and we recommend the reader to also consult the corresponding blog post for more background, at https://crascit.com/2016/10/18/test-fixtures-with-cmake-ctest/. The motivation for this recipe was to demonstrate how to employ test fixtures. These are useful for more sophisticated tests that require setup actions before the test is run, and cleanup actions after it has completed (such as creating an example database, setting up a connection, disconnecting, cleaning up the test database, and so on). We want to make sure that running a test that requires a setup or cleanup action automatically triggers these steps in a predictable and robust way, without introducing code repetition. These setup and cleanup steps can be delegated to the testing framework, such as Google Test or Catch2, but here, we demonstrate how to implement test fixtures at the CMake level.
