class Album(Model):
    ...

class Track(Model):
    album = ForeignKey(Album)

class AlbumSerializer(HyperlinkedModelSerializer):
    ...

class TrackTest(APITestCase):
    def test_track_list(self):
        response = self.client.get(reverse('tracks-list'))
        
        album_url = reverse('album-detail', args=(1,))
        
        expected = [{'album': album_url, ...}]

        # album_url = '/albums/1' but response.data[0]['album'] is 'http://testserver/albums/1'
        self.assertEqual(response.data, expected)
