Bug report
Example test case that can be possibly added to test_datetime.py:
class TestExample(unittest.TestCase):
@classmethod
def setUpClass(cls) -> None:
cls.value_to_test = 1
return super().setUpClass()
def test_example_bug(self):
self.assertEqual(self.value_to_test, 1)./python.exe -m test test_datetime -v -m test_example_bug outputs:
test_example_bug (test.datetimetester.TestExample_Pure.test_example_bug) ... ERROR

I proposed this fix: https://github.com/python/cpython/pull/119675/files#diff-d4ea73ff6f3d1428ce4536793404e64ce7dbc1f6d0afe22f707ee0a24777afea but it was not merged.
