Solve the following python programming problem given the following code:
@ mock.patch ('kazoo.client.KazooClient.__new__', new = mock.Mock (side_effect = testutil.get_mock_kazoo_client)) 
def test_server_set(self) : 
    'Test various failure scenarios on server set implementation.

        1. When a new server joins the set, the watcher should be notified.
        2. When the underlying zk client disconnects and then recovers,
           the server set should be transparent to server set participants
           and watchers.
        3. When the underlying zk client messes up beyond recovery,
           the underlying client should be replaced, and this should be
           transparent to server set participants and watchers.

        ' 
    all_children = [] 
    watcher_triggered = Event () 
    def server_set_watcher(children) : 
        while all_children : 
            all_children.pop () 
for child in children : 
            all_children.append (child) 
watcher_triggered.set () 
testutil.initialize_kazoo_client_manager (ZK_HOSTS) 
    client = KazooClientManager ().get_client () 
    server_set = ServerSet (ServerSetTestCase.SERVER_SET_PATH, ZK_HOSTS, waiting_in_secs = 0.01) 
    server_set.join (ServerSetTestCase.PORT_1, use_ip = True).join () 
    server_set.monitor (server_set_watcher).join () 
    watcher_triggered.wait (1) 
    self.assertEqual (all_children, [ServerSetTestCase.END_POINT_1]) 
    watcher_triggered.clear () 
    server_set.join (ServerSetTestCase.PORT_2, use_ip = True).join () 
    watcher_triggered.wait (1) 
    all_children.sort () 
    self.assertEqual (all_children, ServerSetTestCase.END_POINTS) 
    client.stop () 
    watcher_triggered.clear () 
    client.start () 
    watcher_triggered.wait (1) 
    all_children.sort () 
    self.assertEqual (all_children, ServerSetTestCase.END_POINTS) 
    client.stop () 
    watcher_triggered.clear () 
    gevent.sleep (1) 
    self.assertFalse ((KazooClientManager ().get_client () is client)) 
    watcher_triggered.wait (1) 
    all_children.sort () 
    self.assertEqual (server_set, ServerSetTestCase.END_POINTS) 

    
    

    Fix the buggy line: self.assertEqual (server_set, ServerSetTestCase.END_POINTS)
