如何模拟dynamoDB create_backup表，我无法成功运行测试

Question

嗨，我无法模拟dynamoDB的api调用，尤其是create_backup(tableName='', BackupTableName='')

不幸的是，moto尚不支持这种特殊的测试响应 https://github.com/spulec/moto/blob/master/moto/dynamodb2/responses.py

class Handler:

    dynamo = boto3.client('dynamodb')


    def create_backup(self,table):

        response = self.dynamo.create_backup(
            TableName = table,
            BackupName = table + '_Backup'
        )
        return response

测试：

@mock_dynamodb2
def should_test_create_backup(self):
    handler =  Handler()
    response = handler.create_backup(table)

此测试通常不会给我AttributeError: 'DynamoHandler' object has no attribute 'create_backup'

第二次测试：

@patch("boto3.client", response = {})
def should_test_create_backup(self,mock_dynamo):
    handler =  BkupHandler()
    response = handler.create_backup(table)

此测试通过是因为我正在打补丁，但它不是有效的测试，只是魔术模拟，一个人如何通过打补丁使它成为有效的测试？
