boto3 - 博托斯塔伯 SQS

Question

我需要模拟 Boto SQS 接收消息，但我收到一个错误:

AttributeError: 'Stubber' object has no attribute 'receive_message'

sqs_client 属性是一个Stubber 但receive_message 不被识别，我不知道为什么。

import unittest
from api.modules.sqs_consumer import SqsConsumer
from botocore.stub import Stubber
from botocore.stub import ANY

class TestSqsConsumer(unittest.TestCase):

def test_should(self):
    # given
    sqs_consumer = SqsConsumer()
    sqs_consumer_stup = Stubber(sqs_consumer.sqs_client)

    expected_params = dict(
        QueueUrl=ANY,
        MaxNumberOfMessages=ANY,
        WaitTimeSeconds=ANY,
        MessageAttributeNames=[
            'All'
        ])

    sqs_consumer_stup.add_response(
        method='receive_message',
        service_response={},
        expected_params=expected_params
    )

    sqs_consumer_stup.activate()
    sqs_consumer.sqs_client = sqs_consumer_stup

    # when
    sqs_consumer.process()

    # then
    self.assertEqual(True, True)

if __name__ == '__main__':
    unittest.main()

Answer 1

当您调用激活时，Boto3 stubber 对 boto 客户端进行就地更新。所以你不需要这一行

sqs_consumer.sqs_client = sqs_consumer_stup

以上几行将 sqs_client 替换为您不需要的 Stubber 对象。
