I often find myself testing that the queryset returned by a method contains the instances I expect. I use a custom method, assertQuerysetEqual(), to test the equality of two querysets or lists::

def test_some_values(self):
    qs = get_user_list()
    self.assertQuerysetEqual(qs, [normal_user, super_user])

Makes it easy to test small querysets against lists whose values are known and expected.

from django.test import TestCase

class BaseTestCase(TestCase):
    def assertQuerysetEqual(self, qs1, qs2):
        pk = lambda o: o.pk
        return self.assertEqual(
            list(sorted(qs1, key=pk)),
            list(sorted(qs2, key=pk))
        )
