How do I test authentication in Django views?

To test authentication in Django views, you can use Django's test client to simulate requests and check responses.

Can you show me an example of a test case for a login view?

Sure! You can create a test case like this:

from django.test import TestCase, Client
from django.urls import reverse

class LoginViewTests(TestCase):
    def setUp(self):
        self.client = Client()

    def test_login_view(self):
        response = self.client.post(reverse('login'), {'username': 'user', 'password': 'pass'})
        self.assertEqual(response.status_code, 200)
        self.assertContains(response, 'Welcome')

What about testing access to a protected view?

For protected views, you can check if a user is redirected to the login page when not authenticated. Here's an example:

class ProtectedViewTests(TestCase):
    def test_protected_view_redirects(self):
        response = self.client.get(reverse('protected_view'))
        self.assertRedirects(response, '/login/?next=/protected_view/')
