What is unit testing in Python?

Unit testing in Python is a method to test individual units of code to ensure they work as intended.

Why is unit testing important?

Unit testing helps catch bugs early, improves code quality, and makes future changes safer and easier.

How do I write a unit test in Python?

You can use the unittest module. Define a test case class that inherits from unittest.TestCase and write test methods.

Can you show me a simple example?

Sure! Here's a basic example:

import unittest

def add(a, b):
    return a + b

class TestAddFunction(unittest.TestCase):
    def test_add(self):
        self.assertEqual(add(1, 2), 3)

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