Django testing - NoReverseMatch

Question

Why is this test does not work?

This is my views.py:

class ObjectDetailView(LoginRequiredMixin, DetailView):
    template_name = "object-detail.html"
    model = Object
    slug_field = 'username'

    def dispatch(self, request, *args, **kwargs):
        ....

urls.py:

url(r'^object/details/(?P<slug>[-\w.]+)/$', ObjectDetailView.as_view(), name='object-details'),

tests.py:

class ObjectViewsTestCase(TestCase):
    fixtures = ['/app/fixtures/object_fixture.json', ]

    def test_object_details(self):
        user = User.objects.get(id=1)
        self.client.login(username=user.username, password=user.password)
        resp = self.client.get(reverse('object-details', kwargs={'slug': user.username}))
        self.assertEqual(resp.status_code, 200)

My error:

NoReverseMatch: Reverse for 'object-details' with arguments '()' and keyword arguments '{'slug': u'admin'}' not found. 0 pattern(s) tried: []

Do you have a ROOT_URLCONF in your settings ? If so, make sure that when you run the tests these settings are loaded. Or you can add the following in your tests :

class ObjectViewsTestCase(TestCase):
    fixtures = ['/app/fixtures/object_fixture.json', ]
    urls = 'path.to.your.urls'  # for instance 'base.app.urls'
