[Fixed]-Django test client does not log in

You cannot access the password directly. The password attribute is encrypted. (See Password management in Django.)

For example, here sample output of password.

>>> user = User.objects.create_user(username='asdf', email='asdf@example.com', password='xxxx')
>>> user.password
'sha1$166e7$4028738f0c0df0e7ec3cec06843c35d2b5a1aae8'

As you can see, user.password is not xxxx I given.

I’d modify create_user to accept optional password parameter. And pass a password both to create_user, and client.login as follow:

def setUp(self):
    """
    Initializes the test client and logs it in.
    """
    password = 'secret'
    self.user = create_user(password=password)
    self.logged_in = self.client.login(username=self.user.username, password=password)

UPDATE

create_user should use User.objects.create_user instead of User.objects.create. And the created user object should be returned:

def create_user(username=None, password=None, email=None, is_superuser=False):
    if username is None:
        username = "user%d" % Static.user_count
        while User.objects.filter(username=username).count() != 0:
            Static.user_count += 1
            username = "user%d" % Static.user_count
    if password is None:
        password = "password"
    if email is None:
        email="user%d@test.com" % Static.user_count

    Static.user_count += 1
    user = User.objects.create_user(username=username, password=password)
    #                   ^^^^^^^^^^^
    user.is_superuser = is_superuser
    user.save()
    return user # <---
