pre-commit cache contains tests folder about flake8 HOT 2 CLOSED

I believe based on the python pre-commit documentation that if I read between the lines there's a git clone (or an archive tarball downloaded from the latest tag on GitHub) and then a pip install . in that directory. If the former is more/less true, this isn't a Flake8 only problem. Any python pre-commit hook that includes the tests in its repository will have this issue for you based on where you put the directory.

You can also update how you run pytest. For example you can tell pytest to not recurse the .cache directory

You can also just not put the directory in your current repository root in CI. There's many ways to fix this but I don't think this is either a Flake8 bug or a pre-commit bug.

I also strongly discourage running tests in pre-commit as it's far too slow and will frustrated your contributors
