Hey Jesse,

try it this way:

###############

class Connection:
    def __init__(self, sender):
        self.sender = sender

    def send_file(self, file):
        self.sender.send(file)


class MockSender:
    def __init__(self):
         self.files_sent=[]
    def send(self, file):
         self.files_sent.append(file)        


class ConnectionTestCase(unittest.TestCase):

    def testFileSent(self):
        s = MockSender()
        c = Connection (s)
        c.send_file(TEST_FILE)
        assert TEST_FILE in s.files_sent[],
            'TEST_FILE not found in listfiles return value!'

##########

See how you can now pass in a RealSender instance with a
real send() method?
