Solve the following python programming problem given the following code:
@ patch ('pyon.net.messaging.gevent.spawn', return_value = sentinel.ioloop_process) 
def test_make_node(self, gevmock) : 
    connection_params = { 
        'username' : sentinel.username, 
        'password' : sentinel.password, 
        'host' : str (sentinel.host), 
        'vhost' : sentinel.vhost, 
        'port' : 2111, 
} 
    cm = Mock () 
    def select_connection(params, cb) : 
        cb (cm) 
        return sentinel.connection 
with patch ('pyon.net.messaging.PyonSelectConnection', new = self) : 
        (node, ilp) = make_node (connection_params, name = sentinel.name) 
self.assertEquals (ilp, sentinel.ioloop_process) 
    gevmock.assert_called_once_with (ioloop, sentinel.connection, name = sentinel.name)
