python-2.7 - moto with boto3 - 无法构建模拟 ELB

Question

我是 moto 和 aws 的新手，所以我正在尝试为 aws 中的简单 ELB 检查器编写一些简单的测试用例。

我在这里阅读了 moto 页面：

https://github.com/spulec/moto

我在这里遵循 boto3 指南：

https://boto3.readthedocs.io/en/latest/reference/services/elb.html

但我认为我不了解如何将 moto 与 boto3 一起使用。以下是我的代码和错误，任何帮助将不胜感激。

# # -*- coding: utf-8 -*-

from .context import elb_tools

from nose.tools import set_trace; 
import unittest

from moto.elb import mock_elb
import boto3



class TestElbTools(unittest.TestCase):
    """Basic test cases."""

    def setUp(self):
        pass

    @mock_elb
    def test_check_elb_has_attached_instances(self):
        empty_elb = mock_elb
        mock_elb.describe_load_balancers()

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

输出：

D:\dev\git_repos\platform-health>nosetests
E

好的，所以我得到了朋友的帮助。下面应该做的伎俩

# # -*- coding: utf-8 -*-

from .context import elb_tools

from nose.tools import set_trace; 
import unittest

from moto.elb import mock_elb
import boto3

class TestElbTools(unittest.TestCase):
    """Basic test cases."""

    def setUp(self):
        #pass
        self.region = 'ap-southeast-2'

    @mock_elb
    def test_check_elb_has_attached_instances(self):
        elb_client = boto3.client('elb', region_name=self.region)
        set_trace()
        elb_client.describe_load_balancers()

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