Solve the following python programming problem given the following code:
@ defer.inlineCallbacks 
def test_reconnect_if_connect_fails(self) : 
    connection = providers.AMQPConnection ('test_name', servers = ['tcp:host=server_1:port=5672', 'tcp:host=server_2:port=5673'], reconnect_interval = 0) 
    connection.setServiceParent (self.service) 
    endpoints = list () 
    connect_return_values = [error.ConnectError ('test_error'), error.DNSLookupError ('test_error'), error.ConnectionDone ('test_error'), Exception ('test_exception'), defer.Deferred ()] 
    expected_errors = list (connect_return_values [: (- 1)]) 
    disconnects = list () 
    connection.on_disconnected += disconnects.append 
    with patch.object (connection, '_connect') as mocked_connect : 
        def connect(endpoint) : 
            endpoints.append (dict (host = endpoint._host, port = endpoint._port)) 
            return_value = connect_return_values.pop (0) 
            if isinstance (return_value, Exception) : 
                raise return_value 
return return_value 
mocked_connect.side_effect = connect_return_values 
        with patch.object (providers.logger, 'warn') as mocked_warn : 
            connection.startService () 
            while connect_return_values : 
                (yield util.wait (0)) 
self.assertEquals (mocked_warn.call_count, len (expected_errors)) 
server_1 = dict (host = 'server_1', port = 5672) 
        server_2 = dict (host = 'server_2', port = 5673) 
        self.assertEquals (endpoints, [server_1, server_2, server_1, server_2, server_1]) 
        errors = [disconnect.value for disconnect in disconnects] 
        self.assertEquals (errors, expected_errors) 
self.assertIsInstance (connection._reconnecting, defer.Deferred) 

    
    

    Fix the buggy line: mocked_connect.side_effect = connect_return_values
