使用mock解决测试中依赖第三方接口的问题

import requests
class users:
    def url_list(self):
        res = requests.get("http://localhost:2020")
        return res

from unittest.mock import patch
from shot_tweeter import users
import unittest
class Test_sss(unittest.TestCase):
    @patch("shot_tweeter.users.url_list")#方法名称
    def test_user(self,mock_list_user):
        mock_list_user.return_value.status_code = 200#设定返回值
        mock_list_user.return_value.json.return_value = {"data":["ok"]}#设定返回值
        u = users()
        resp = u.url_list()
        assert resp.status_code ==200

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