Not GP but when I feel like I'm going crazy I insert an "assert False" test into my test suite. It's a good way to reveal when you're testing a cached version of your code for some reason (for instance integration tests using Docker Compose that aren't picking up your changes because you've forgotten to specify --build or your .dockerignore is misconfigured). But I delete it when I'm done.
