...quoting the contents of `tests/test_ruff_bug.py`, the rule codes PT006, along with the `pyproject.toml` settings and executed command, we'd be very appreciative!
PT006 Wrong type passed to first argument of `pytest.mark.parametrize`; expected `str`

Executed command: ruff check --fix tests/test_ruff_bug.py
If you remove any item in parametrization list, either ((),) or ((1,),), the fix succeeds.
