如何模拟请求和响应? [英] How can I mock requests and the response?

问题描述

我正在尝试使用 Python模拟包来模拟Python requests模块.使我在以下情况下工作的基本要求是什么?

I am trying to use Pythons mock package to mock Pythons requests module. What are the basic calls to get me working in below scenario?

在我的views.py中，我有一个函数，可以使各种request.get()调用每次具有不同的响应

In my views.py, I have a function that makes variety of requests.get() calls with different response each time

def myview(request):
  res1 = requests.get('aurl')
  res2 = request.get('burl')
  res3 = request.get('curl')

在测试类中，我想做这样的事情，但无法找出确切的方法调用

In my test class I want to do something like this but cannot figure out exact method calls

第1步:

# Mock the requests module
# when mockedRequests.get('aurl') is called then return 'a response'
# when mockedRequests.get('burl') is called then return 'b response'
# when mockedRequests.get('curl') is called then return 'c response'

第2步:

呼叫我的视图

第3步:

验证响应包含"a响应"，"b响应"，"c响应"

verify response contains 'a response', 'b response' , 'c response'

如何完成第1步(模拟请求模块)?

How can I complete Step 1 (mocking the requests module)?

推荐答案

这对我有用:

import mock
@mock.patch('requests.get', mock.Mock(side_effect = lambda k:{'aurl': 'a response', 'burl' : 'b response'}.get(k, 'unhandled request %s'%k)))
