I have a peculiar problem with requests_mock. I want to use it with pytest to test my API wrapper library.
I've tried to use the first example in the requests_mock docs, except I put it in a test_mock()-function and added an assert-statement for pytest to discover it.
The following code fails:
# tests/test_mock.pyimport requests
import requests_mockwith requests_mock.Mocker() as m:def test_mock():m.get('http://test.com', text='resp')assert requests.get('http://test.com').text == 'resp'
However, when running the following example in ipython, it works as expected. This is the exact code from the example:
with requests_mock.Mocker() as m:m.get('http://test.com', text='resp')print(requests.get('http://test.com').text)# prints 'resp'
Because I can make requests_mock work from ipython, I assume the issue is with pytest, but I might be wrong.
It seems like the adapter isn't used at all, so that requests sends a real http request to the target url instead of using the mocked object.
I'm using Python 3.6.3 (Anaconda3), requests_mock 1.3.0 and pytest 3.3.0
Output from running the code that fails:
