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

You can use the Flask testing client to simulate requests in your tests. This allows you to test your routes without needing to run the server.

Can you show me a simple example of how to do that?

Sure! Here's a basic example:

from flask import Flask, jsonify
import unittest

app = Flask(__name__)

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

class FlaskTestCase(unittest.TestCase):
    def setUp(self):
        self.app = app.test_client()
        self.app.testing = True

    def test_get_data(self):
        response = self.app.get('/api/data')
        self.assertEqual(response.status_code, 200)
        self.assertEqual(response.json, {'key': 'value'})

if __name__ == '__main__':
    unittest.main()

What if I want to mock a POST request instead?

You can mock a POST request similarly. Just use self.app.post() and provide the necessary data. Here's an example:

response = self.app.post('/api/data', json={'new_key': 'new_value'})
