An attempt to create generic class-based tests for Django

tests.py

class GenericViewTest(TestCase):

    def setUp(self):
        self.client = Client()

    def assertGet(self, num_queries):
        with self.assertNumQueries(num_queries):
            response = self.client.get(self.url)
        self.assertEqual(response.status_code, 200)
        self.context = response.context

    def assertContext(self, key, value):
        self.assertTrue(key in self.context)
        self.assertEqual(self.context[key], value)

    def assertContextLength(self, key, length):
        self.assertTrue(key in self.context)
        self.assertEqual(len(self.context[key]), length)


class DocumentListTest(GenericViewTest):
    fixtures = ['initial_data.json']
    url = reverse("document_list")
    model = Document

    def test_document_number(self):
        self.assertGet(4)
        self.assertContext('documents_active', True)
        self.assertContextLength('document_list', 20)
