How to Effectively Mock Python\'s Requests Module for Testing?

Mocking Requests with Python's Mock Package

To mock Python's requests module effectively, follow these steps:

Step 1: Mock the Requests Module

To mock the requests module in the context of your test class, utilize the following syntax:

<code class="python">import mock
@mock.patch('requests.get')
def test_function(self, mockedRequests):</code>

Inside the test function:

• Assign the 'aurl', 'burl', and 'curl' calls to the mockedRequests object, specifying the desired return values for each URL.

Example:

<code class="python">mockedRequests.get('aurl').return_value = 'a response'
mockedRequests.get('burl').return_value = 'b response'
mockedRequests.get('curl').return_value = 'c response'</code>

Step 2: Call the View Function

In your test case, call the myview function to execute the HTTP requests.

Step 3: Verify Response

Assert that the response objects contain the expected values ('a response', 'b response', 'c response').

Example:

<code class="python">res1 = myview(request)
self.assertIn('a response', res1)
res2 = myview(request)
self.assertIn('b response', res2)
res3 = myview(request)
self.assertIn('c response', res3)</code>

Example Code:

<code class="python">import unittest
import mock
from views import myview

# Mock the requests module
@mock.patch('requests.get')
def test_myview(self, mockedRequests):
    # Define return values for URL calls
    mockedRequests.get('aurl').return_value = 'a response'
    mockedRequests.get('burl').return_value = 'b response'
    mockedRequests.get('curl').return_value = 'c response'

    # Call the view function
    res1 = myview(request)
    res2 = myview(request)
    res3 = myview(request)

    # Verify response
    self.assertIn('a response', res1)
    self.assertIn('b response', res2)
    self.assertIn('c response', res3)

if __name__ == '__main__':
    unittest.main()</code>
