Django: test failing on a view with @login_required

问题

I'm trying to build a test for a view that's decorated with @login_required, since I failed to make it work, I did a simple test and still can't make it pass.

Here is the code for the simple test and the view:

def test_login(self):
    user = self._create_new_user()
    self.assertTrue(user.is_active)
    login = self.client.login(username=user.username,
password=self.data['password1'])
    self.failUnless(login, 'Could not log in')
    response = self.client.get('/accounts/testlogin/')
    self.assertEqual(response.status_code, 200)

@login_required
def testlogin(request):
    print 'testlogin !! '
    return HttpResponse('OK')

_create_new_user() is saving the user and there is a test inside that method to see that is working.

The test fails in the response.status_code, returning 302 and the response instance is of a HttpResponseRedirect, is redirecting it as if not logged in.

Any clue? I'm missing something?

This testcase works for me:

from django.contrib.auth.models import User
from django.core.urlresolvers import reverse
from django.test.client import Client
import unittest

class LoginTestCase(unittest.TestCase):
    def setUp(self):
        self.client = Client()
        self.user = User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword')

    def testLogin(self):
        self.client.login(username='john', password='johnpassword')
        response = self.client.get(reverse('testlogin-view'))
        self.assertEqual(response.status_code, 200)

I suggest you (if you don't use them already) to use the reverse() function and name your URLs. This way you are sure that you get always the right URL.

Here is the answer:

Python 2.6.5 made a change to the way cookies are stored which is subtly incompatible with the test client. This problem has been fixed in the 1.1.X and trunk branches, but the fix hasn't yet made it into a formal release.

If you are using 1.1.X and Python 2.6.5, you're going to have problems with any test activity involving cookies. You either need to downgrade Python, or use the 1.1.X branch rather than the 1.1.1 release.

A 1.1.2 release (that will include the fix for the problem you describe) will be made at the same time that we release 1.2 - hopefully, very very soon.

OK I was to facing same problem @resto solved my problem.

creating user this way below, lets the test client get the user logged in and get the response other than redirect (302)

self.user = User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword')
