Better TestCase for test response.
Replace your code:
class FooTestCase(TestCase):
def test_status_code(self):
url = reverse('view-path', args=(10,))
response = self.client.get(url)
self.assertEqual(response.status_code, 200)
with this:
class FooTestCase(ResponseTestCase):
def test_status_code(self):
response = self.get(('view-path', args=(10,)))
self.assertOK(response)
