Change Django Authentication Backend for Testing

My Django site uses the LDAP backend for authentication in production, but this is not suitable for testing (impossible to create requests from dummy users). How can I disable this backend, solely for tests?

Here is the relevant settings.py section:

    AUTHENTICATION_BACKENDS = (
#'crowd.backend.CrowdBackend',
# 'django_auth_ldap.backend.LDAPBackend',
'django.contrib.auth.backends.ModelBackend',
    )
   AUTH_LDAP_SERVER_URI = "ldap://ldap.cablelabs.com"
   import ldap
   from django_auth_ldap.config import LDAPSearch

   AUTH_LDAP_BIND_DN = "CN=CableLabs  Internal,OU=cabletest,OU=Teamwork,OU=community,DC=cablelabs,DC=com"
   AUTH_LDAP_BIND_PASSWORD = "UAq,0@ki"
   AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=community,dc=cablelabs,dc=com",ldap.SCOPE_SUBTREE, "(sAMAccountName=%(user)s)")
   AUTH_LDAP_USER_ATTR_MAP = {"first_name": "givenName", "last_name": "sn","username":"sAMAccountName","email":"mail","photo":"thumbnailPhoto"} 
   AUTH_LDAP_CONNECTION_OPTIONS = {
     ldap.OPT_REFERRALS: 0
   }

For future reference, another option to look into for testing is to change the is_authenticated property of the User object to a lambda. For example:

user = User(...)
user.is_authenticated = lambda: True

If you only need/want to disable the backend for certain tests, you can also use the override_settings decorator. You can use this decorator on the test case class:

from django.test.utils import override_settings

@override_settings(AUTHENTICATION_BACKENDS=
                   ('django.contrib.auth.backends.ModelBackend',))
class FooTest(TestCase):

    def test_bar(self):
        pass

But you can also selectively use it on a test method:

from django.test.utils import override_settings

class FooTest(TestCase):

    @override_settings(AUTHENTICATION_BACKENDS=
                       ('django.contrib.auth.backends.ModelBackend',))
    def test_bar(self):
        pass

Create an alternative settings file, for example myproj/test_settings.py, and specify that settings file when running unit tests.

Write the alternative settings file like this:

from myproj.settings import *

AUTHENTICATION_BACKENDS = (
        #'your.ldap.backend',
        'django.contrib.auth.backends.ModelBackend',
        )

That is, the settings inherits everything from your regular settings, but overrides the AUTHENTICATION_BACKENDS definition, with your LDAP backend commented out.

Then, run your tests like this:

python manage.py test --settings=myproj.test_settings
