How do I test my Flask application using unittest?

You can use the unittest module in Python to create test cases for your Flask application. Start by importing the necessary modules.

Can you show me a simple example of a test case?

Sure! Here's a basic example:

import unittest
from myapp import app

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

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

What should I include in the setup method?

In the setup method, you typically create a test client and set the app to testing mode. This allows you to simulate requests.

How do I run the tests?

You can run the tests by executing the command python -m unittest in your terminal. It will discover and run all test cases.
