Circular import detected

[Max Görner]

I wanted to write a test whether arbitrary invalid code can be handled correctly. The test can be found below; I had it in src/tests/fuzzing_test.py. EDIT: I reduced the "test" to the bare minimum necessary to reproduce the problem.

When I try to execute this test using poetry run pytest src/tests/fuzzing_test.py I get an error message that complains about possible circular imports. I have no idea how that is possible and thus wanted to escalate this to the maintainer. The error message can be found below the source code.

I created the following and it worked:

from tryceratops.files.discovery import FileDiscovery


def test_a():
    FileDiscovery()
