Could not login user using test.client.Client.login when 'django.contrib.sessions' is not in settings.INSTALLED_APPS

[anonymous]

Hello,

I'm using django session based on cache, so I don't put 'django.contrib.sessions' in INSTALLED_APPS. Everything works fine except the tests (user login attempt always fails).

In django.test.client.Client.login line 549, there is condition:

if user and user.is_active \
     and 'django.contrib.sessions' in settings.INSTALLED_APPS:
   ...

Why do we need this part:

'django.contrib.sessions' in settings.INSTALLED_APPS

?

I think perhaps the check should be for SESSION_BACKEND
