我对requests_mock
有一个奇怪的问题。我想将它与pytest
一起使用来测试我的API包装器库。
我尝试使用first example in the requests_mock docs,除了我把它放在 test_mock() -function中并为pytest添加assert
- 语句以便发现它
以下代码失败:
# tests/test_mock.py
import requests
import requests_mock
with requests_mock.Mocker() as m:
def test_mock():
m.get('http://test.com', text='resp')
assert requests.get('http://test.com').text == 'resp'
但是,在ipython中运行以下示例时,它按预期工作。这是example:
中的确切代码with requests_mock.Mocker() as m:
m.get('http://test.com', text='resp')
print(requests.get('http://test.com').text)
# prints 'resp'
因为我可以让requests_mock
从ipython开始工作,我认为问题出在pytest上,但我可能错了。
似乎根本没有使用适配器,因此请求会向目标网址发送真实的http请求,而不是使用模拟对象。
我使用的是Python 3.6.3(Anaconda3),requests_mock 1.3.0和pytest 3.3.0
运行失败代码的输出:

答案 0 :(得分:3)
为什么它在IPython中起作用对我来说似乎是一个谜。要解决这个问题,只需将函数定义的行与上下文管理器的开头交换。
# tests/test_mock.py
import requests
import requests_mock
def test_mock():
with requests_mock.Mocker() as m:
m.get('http://test.com', text='resp')
assert requests.get('http://test.com').text == 'resp'
