D403 not triggering when it should

[cazador481]

I am seeing D4-3 not hitting a number of cases where flake8 is.
To replicate ruff test.py --select D403 -n --isolated

Code:

"""Contains tests for the configuration library."""
import unittest


class BasicConfigurationTest(unittest.TestCase):
    """Doc string."""

    @classmethod
    def setUpClass(cls):
        """runs just once when the class instance is setup."""
        pass

I expect the docstring for setUpClass to catch the lower case runs, which is a D403 error

Flake8 catches the error:

poetry run flake8 test.py
test.py:10:1: D403 First word of the first line should be properly capitalized

I am using ruff version
poetry run ruff --version
ruff 0.0.247

Thanks, just an oversight!
