Overriding timezone in test forces them to be TestCase

[tpazderka]

Changing settings of timezone during tests forces them to be TestCase instead of SimpleTestCase. I do believe that this change shouldn't force the test to be TestCase.
Testcase:

from django.test import SimpleTestCase, override_settings


class TimezoneTest(SimpleTestCase):
    def test_tz(self):
        with override_settings(USE_TZ=False):
            pass
        with override_settings(USE_TZ=True):
            pass

The only query executed during this test is:

SET TIME ZONE 'Europe/Prague'

Looks like a duplicate of #26712, please reopen with more details if not.

[tpazderka]

Yes, that is indeed the case. Is there a backport planned to 1.10?

[Tim Graham]

No, I don't think it qualifies per our ​supported versions policy.

[tpazderka]

I think that it could be considered as a regression since this test starts to fail in 1.9, but passes up until then.

You can use ​SimpleTestCase.allow_database_queries.

Replying to timgraham:

You can use ​SimpleTestCase.allow_database_queries.

Yes, I know. We were hoping to avoid that. Thanks for the consideration.
