Pytest lint made me do weird things, because:

PT004 Fixture `setup_request_summary_logger` does not return anything, add leading underscore

And then:

def test_request_summary(caplog, test_client, _setup_request_summary_logger):
     # ...

PT019 Fixture `_setup_request_summary_logger` without value is injected as parameter, use `@pytest.mark.usefixtures` instead
