I have 2 python files: 1 for unit testing (tests.py) and 1 for the script I want to test (main.py):

# In main.py:

import requests

def get_response(url):
 response = requests.get(url);
 # Do stuff...
 return response

-

# In tests.py

from unittest import mock
from unittest.mock import patch
from my_project.main import get_response

def some_handler(url):
 return "test_response"

class GetResponseTestCase(unittest.TestCase):

 def setUp(self):

 # setup mocks
 patch('requests.get', mock.Mock(side_effect=some_handler)

 def run_test(self):

 result = get_response("test_response")

I want to patch requests.get to return test_response but the patching is not working because it tries to send a request/make a connection to the url supplied. I think the patch name requests.get is not targeting the place it is being used in main.py (as it is referring to where it is defined instead) as some people have mentioned online. But in this scenario I am not sure how to fix this.

If import requests is being used in main.py then how can I patch it from another file? Thanks.

1. Mock get_reponse instead of mocking requests.get(mocking in-built functions;whi le being possible in python is not needed for such a simple usecase).


2. Set return value of mocked get_response function to "test_response".

In tests.py

from unittest import mock

class GetResponseTestCase(unittest.TestCase):

 @mock.patch("my_project.main.get_response") ##mocking get_response
 def run_test(self, mocked_get_response):
 mocked_get_response.return_value = "test_response" ## setting return value

Found that I need to add .start() at the end of the call to creating the patch:

# setup mocks
patch('requests.get', mock.Mock(side_effect=some_handler).start()

If there are any issues with this solution, or a better way for handling this, I would love to hear it!
