Django Rest Framework test fails or passes, depending on number of functions in APITestCase class

Hei all,

I have an issue with a test class (APITestCase) where a function can pass the test if it is the only function within the class, or fail, if it is one of two or more functions.

I have put this question on Stack Overflow where it is available with nicer formatting. 

https://stackoverflow.com/questions/58530256/django-rest-framework-tests-fail-and-pass-depending-on-number-of-functions

If I run the following, the test will succeed.

class AudioTests(APITestCase):

    # setup a test user and a factory

    # factory = APIRequestFactory()

    test_user = None

    @classmethod

    def setUpTestData(cls):

        importer()  # imports data into the database

        cls.test_user = User(username='jim', password='monkey123', email='jim@jim.com')

        cls.test_user.save()

    def test_audio_retrieve(self):

        """

            Check that audio returns a 200 OK

        """

        factory = APIRequestFactory()

        view = AudioViewSet.as_view(actions={'get': 'retrieve'})

        # Make an authenticated request to the view...

        request = factory.get('/api/v1/audio/')

        # force refresh of user

        self.test_user.refresh_from_db()

        user = User.objects.get(username='jim')

        

        force_authenticate(request, user=user)

        response = view(request, pk="2")

        self.assertContains(response, 'audio')

        self.assertEqual(response.status_code, status.HTTP_200_OK)

But if I add a second method as show in the code below, the newly added test_audio_list() will pass, but the previously passing test_audio_retrieve() will fail with a 404.

class AudioTests(APITestCase):

    # setup a test user and a factory

    # factory = APIRequestFactory()

    test_user = None

    @classmethod

    def setUpTestData(cls):

        importer()  # imports data into the database

        cls.test_user = User(username='jim', password='monkey123', email='jim@jim.com')

        cls.test_user.save()

    def test_audio_list(self):

        """

            Check that audo returns a 200 OK

        """

        factory = APIRequestFactory()

        view = AudioViewSet.as_view(actions={'get': 'list'})

        # Make an authenticated request to the view...

        request = factory.get('/api/v1/audio/')

        self.test_user.refresh_from_db()

        force_authenticate(request, user=self.test_user)

        response = view(request, pk="1")

        self.assertContains(response, 'audio/c1ha')

        self.assertEqual(response.status_code, status.HTTP_200_OK)

    def test_audio_retrieve(self):

        """

            Check that audio returns a 200 OK

        """

        factory = APIRequestFactory()

        view = AudioViewSet.as_view(actions={'get': 'retrieve'})

        # Make an authenticated request to the view...

        request = factory.get('/api/v1/audio/')

        # force refresh of user

        self.test_user.refresh_from_db()

        user = User.objects.get(username='jim')

        

        force_authenticate(request, user=user)

        response = view(request, pk="2")

        self.assertContains(response, 'audio')

        self.assertEqual(response.status_code, status.HTTP_200_OK)

I'm going slightly crackers trying to find out what's going run, but I am completely out of ideas. Any light anyone can shed on this is much appreciated.

Cheers,

Conor
