How can I use Flask to mock requests in my tests?

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

Yes, please provide a code example.

Here's a simple example:

from unittest.mock import patch
from flask import Flask

app = Flask(__name__)

@app.route('/api/data')
def get_data():
    return {'key': 'value'}

# Test function
@patch('requests.get')
def test_get_data(mock_get):
    mock_get.return_value.json.return_value = {'key': 'mocked_value'}
    response = app.test_client().get('/api/data')
    assert response.json == {'key': 'mocked_value'}

What if I want to mock a POST request instead?

You can mock a POST request similarly. Just change the method in the test client. Would you like to see that example?
