[Fix error] `PT006` parametrize with single fixture where one of the values is an empty tuple

[BlankSpruce]

Minified example tests/test_ruff_bug.py:

import pytest


@pytest.mark.parametrize(
    ["whatever"],
    [
        ((),),
        ((1,),),
    ],
)
def test_pt006_fix_error(whatever):
    assert 1 + 2 > sum(whatever)

Output:

error: Fix introduced a syntax error. Reverting all changes.

This indicates a bug in Ruff. If you could open an issue at:

...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`

4 | @pytest.mark.parametrize(
5 |     ["whatever"],
  |     ^^^^^^^^^^^^
6 |     [
7 |         ((),),
  |
help: Use a string for the first argument

pyproject.toml:

[tool.ruff.lint]
select = ["PT006"]

Executed command: ruff check --fix tests/test_ruff_bug.py

If you remove any item in parametrization list, either ((),) or ((1,),), the fix succeeds.
