False positive PT019 with monkey patching and _ in test signature

[jamesbraza]

Bug report

What's wrong

from unittest.mock import patch


@patch("time.sleep")
def test_foo(_) -> None:
    _ = 0

Running flake8-pytest-style==1.6.0 on this, it reports:

a.py:5:1: PT019 fixture _ without value is injected as parameter, use @pytest.mark.usefixtures instead

How it should work

I think this should not be getting PT019, as I:

• Am required to have something in the signature for the patched MagicMock
• But I don't plan on using it, so I named it _
• Don't have a fixture _ declared in the module

System information

• Operating system: macOS Monterey version 12.6
• Python version: 3.10.9
• flake8 version: 6.0.0
• flake8-pytest-style version: 1.6.0

Actually, I believe this is a dup of #202, so if you want to close this as a duplicate, feel free.

Yes, this is a dup of #202
