How do I test a Flask API?

You can test a Flask API using tools like Postman or by writing unit tests with Flask's built-in testing capabilities.

Can you show me an example of a unit test for a Flask API?

Sure! Here's a simple example:

import unittest
from my_flask_app import app

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

    def test_get_endpoint(self):
        response = self.app.get('/api/endpoint')
        self.assertEqual(response.status_code, 200)

What libraries do I need to install for testing?

You typically need Flask, Flask-Testing, and unittest which is included in Python's standard library.

How can I automate these tests?

You can use CI/CD tools like GitHub Actions or Travis CI to automate your tests whenever you push code.
