Hi everybody,

I have a Class based view:

```auto
class PromocionListView(ListView):
    model = Promocion

```

and this url path:

```auto
urlpatterns = [
    path('promocion/list', PromocionListView.as_view(), name='promocion_list')]

```

so I made the following test:

```auto
class PromocionTests(TestCase):

    @classmethod
    def setUpTestData(cls):
        cls.promocion = Promocion.objects.create(fecha_de_inicio = date(2022,7,6),duracion = 90)

    def test_url_exists_at_correct_location(self):
        response = self.client.get('promocion/list')
        self.assertEqual(response.status_code, 200)

```

but it is showing the error: AssertionError: 404 != 200. Does anything knows why this is happening? I googled it a lot but I couldn’t find an answer

Is that url in your root urls.py file? If not, what urls.py file is it in and what url leads you to that entry?

Have you tried accessing that url as an absolute url? (`/promocion/list`)

Additionally if you install [django-extensions](https://django-extensions.readthedocs.io/en/latest/) there’s a really neat command called [`show_urls`](https://django-extensions.readthedocs.io/en/latest/command_extensions.html). I use that frequently when I’m having Django URL routing issues.

Hello, thanks for answer. No, the url lives in he urls.py file of the app.  
`urlpatterns = [... path('dashboard/', include('dashboard.urls'))]`  
as you can see the app’s name is dashboard, so it is included in the root urls.py file. The dahsboard app has its own urls.py file whit the path that I write in the question in it. Sorry for my bad english. I hope you can understand me 😊  
I also tried to to access the url in the way you´re pointing. But it doesn´t still work

If the full path of that url is /dashboard/promocion/list, then _that_ is the url you need to use.
