Question

我有一个 python 方法，它使用 boto3 get_paginator 根据一些标签和一些名称列出某些 ECS Fargate 服务。

def list_service_name(environment,
                      resource_owner_name,
                      ecs_client):
    list_of_service = list()
    cluster_name = "my cluster name " + environment
    target_string = "-somedummy"
    resource_owner_tag = resource_owner_name
    service_paginator = ecs_client.get_paginator('list_services')
    for page in service_paginator.paginate(cluster=cluster_name,
                                           launchType='FARGATE'):
       
        for service in page['serviceArns']:

           
            response = ecs_client.list_tags_for_resource(resourceArn=service)
           
            for tags in response['tags']:
                if tags['key'] == 'ResourceOwner' and \
                        tags['value'] == resource_owner_tag and \
                        service.endswith(target_string):
                    list_of_service.append(service)

    return list_of_service

现在我想用moto测试一下。因此，我创建了 conftest.py，我在其中定义了与 ecs 等服务的所有 moto 模拟连接。此外，我创建了如下所示的 test_main.py 文件，其中我创建了连接到 ECS Fargate 的虚拟服务。但出于某种原因，如果我尝试断言测试文件中 main 方法的结果，服务列表将返回 empty。而我希望看到 test-service-for-successful 作为结果。是否有我遗漏的内容或 moto 中的分页仍然不可用？
