In Python REST APIs, how do I write integration tests?

In Python REST APIs, writing integration tests is crucial for ensuring that different parts of your application work together as expected. Integration tests typically test multiple components of your application to ensure they cooperate correctly. Below is an example of how to write integration tests using the Flask testing framework.

from flask import Flask, jsonify from flask_testing import TestCase app = Flask(__name__) @app.route('/api/data', methods=['GET']) def get_data(): return jsonify({"message": "success", "data": [1, 2, 3]}) class TestAPI(TestCase): def create_app(self): app.config['TESTING'] = True return app def test_get_data(self): response = self.client.get('/api/data') self.assert200(response) json_data = response.get_json() self.assertEqual(json_data['message'], 'success') self.assertEqual(json_data['data'], [1, 2, 3]) if __name__ == '__main__': import unittest unittest.main()
