Re: suggestion for dependency injection in view tests

Here is one approach...

class FBFriends:
def get_friends(self, current_user):
return __get_friends(current_user) # heavy call

def suggest(request, usrid=None, friend_source=FBFriends()):
current_user = request.facebook.user
facebook_friends = friend_source.get_friends(current_user)

Meanwhile, in tests.py...

class FBFriendsMock:
def get_friends(self, current_user):
return [(2, 'John Doe'), (4, 'Jane Doe'), (5, 'The Frog')]

def test_suggest(self):
request = some_hand_crafted_request()
response = suggest(request, friend_source=FBFriendsMock())
self.assertEqual(response.status_code, 200) # or whatever
