Rule PT019 Treats Unused Mocks as Fixtures when prefixed with underscores

[max-muoto]

Rule PT019 flags unused mock arguments prefixed with underscores as Pytest fixtures.

Example

from unittest import mock

# `_func` gets treated as unused fixture, failing a `ruff check`.
@mock.patch("func")
def test(_func):
    assert 1 == 1

Details

• Ruff version: v0.0.286
• Command: ruff check .

@charliermarsh Understand this is probably just due to fixture naming conventions, but just thought I would flag in case!
