Also, depending on your scenario, the classes might be overkill. You
could just as easily pass in a callable. In that case your view would
look something like this...
def suggest(request, usrid=None, get_friends=__get_friends):
current_user = request.facebook.user
facebook_friends = get_friends(current_user)
..and your test would look something like this...
def pretend_get_friends(current_user):
return [(2, 'John Doe'), (4, 'Jane Doe'), (5, 'The Frog')]
def test_suggest(self):
request = some_hand_crafted_request()
response = suggest(request, get_friends=pretend_get_friends)
self.assertEqual(response.status_code, 200) # or whatever
