`tests/test_tornado.py::TestTornado - AttributeError: 'TestTornado' object has no attribute 'runTest'` w/ pytest-8.2.0

When trying to run tests, I'm getting the following error:

This is a regression after upgrading to pytest-8.2.0.

Although its a Tornado issue. I made the test work by adding:

class TestTornado(testing.AsyncTestCase):  # type: ignore[misc]
    ...
    def runTest(self):
        self.subTest()

Just waiting for the fix. :smile:

Could you please drop the patch for that? 🤔

The patch is not expected in tenacity rather it is from tornado's side. Refer:
