Solve the following python programming problem given the following code:
def _test_scheduler_api(self, method, rpc_method, expected_args = None, **kwargs) : 
    ctxt = context.RequestContext ('fake_user', 'fake_project') 
    rpcapi = scheduler_rpcapi.SchedulerAPI () 
    self.assertIsNotNone (rpcapi.client) 
    self.assertEqual (rpcapi.client.target.topic, CONF.scheduler_topic) 
    expected_retval = ('foo' if (rpc_method == 'call') else None) 
    expected_version = kwargs.pop ('version', None) 
    expected_fanout = kwargs.pop ('fanout', None) 
    expected_kwargs = kwargs.copy () 
    if expected_args : 
        expected_kwargs = expected_version 
prepare_kwargs = { 
        
} 
    if expected_fanout : 
        prepare_kwargs ['fanout'] = True 
if expected_version : 
        prepare_kwargs ['version'] = expected_version 
orig_prepare = rpcapi.client.prepare 
    def fake_can_send_version(version = None) : 
        return orig_prepare (version = version).can_send_version () 
@ mock.patch.object (rpcapi.client, rpc_method, return_value = expected_retval) 
    @ mock.patch.object (rpcapi.client, 'prepare', return_value = rpcapi.client) 
    @ mock.patch.object (rpcapi.client, 'can_send_version', side_effect = fake_can_send_version) 
    def do_test(mock_csv, mock_prepare, mock_rpc_method) : 
        retval = getattr (rpcapi, method) (ctxt, ** kwargs) 
        self.assertEqual (retval, expected_retval) 
        mock_prepare.assert_called_once_with (** prepare_kwargs) 
        mock_rpc_method.assert_called_once_with (ctxt, method, ** expected_kwargs) 
do_test ()
