PR summary
Python 3.12 added the
skip_file_prefixes
argument, which essentially does what this helper function does for us.Technically, I think the old implementation would set the stack level to the tests, if called in one, but this one doesn't. However, that shouldn't be a problem, as either 1) warnings are errors, or 2), we catch the warning with
pytest.warns
and don't see the stack level.PR checklist
