How can I mock HTTP requests in Python for testing?

You can use the unittest.mock library to mock HTTP requests in Python. Would you like a code example?

Yes, please provide a code example.

Here's a simple example using the requests library and unittest.mock:

import requests
from unittest.mock import patch

@patch('requests.get')
def test_mocked_get(mock_get):
    mock_get.return_value.status_code = 200
    mock_get.return_value.json.return_value = {'key': 'value'}

    response = requests.get('http://example.com')
    assert response.status_code == 200
    assert response.json() == {'key': 'value'}

What if I want to mock a POST request instead?

You can mock a POST request in a similar way. Just use requests.post in the @patch decorator. Would you like to see that example?
