From Django documentation: To compare two model instances, just use the standard Python comparison operator, the double equals sign: ==. Behind the scenes, that compares the primary key values of two models.
For a specific test inside a test case, you can use the override_settings decorator: from django.test.utils import override_settings from django.conf import settings class TestSomething(TestCase): @override_settings(DEBUG=True) def test_debug(self): assert settings.DEBUG
