I'm not finding the way to get when the PermissionDenied error is raised.
This test try to catch a Permission Denied on a Django, it is expected just to accept staff user or return a 403 status_code
This is the code:
from django.contrib.auth.models import User
from django.core.exceptions import PermissionDenied
from django.test import Client, TestCase
from django.urls import reverse
from scrapers.models import Scraper
class PublicWebTestCase(TestCase):
def setUp(self):
# Every test needs a client.
self.client = Client()
# Create staff user (no staff)
self.user = User.objects.create_user('juan', '[email protected]', 'juan')
self.staff_user = User.objects.create_user(
'victor',
'[email protected]',
'Vitor',
is_staff=True
)
self.client.raise_request_exception = True
# crear un scraper para que haya una vista de el
self.scraper = Scraper.objects.create(
name='My Scraper',
folder="X",
)
self.page_url = reverse('scrapers-page')
def test_scrapers_page_for_anon_user(self):
""" Scrapers view as anonymous user """
self.assertRaises(PermissionDenied, self.client.get, self.page_url)
And this is the result I get:
Found 1 test(s).

What am I missing?? Thanks in advance.
I had this same problem. The answer is that when the PermissionDenied() gets raised, the Django middleware catches it and turns that into a 403 Access Denied HTTP response. Change your test to something more like:
response = self.client.get(self.page_url)
self.assertEqual(403, response.status_code)
