1. Organize Tests with Test Classes

Structuring related tests into classes that inherit from unittest.TestCase improves readability and reusability. This approach makes it easier to understand the purpose of each group of tests.

import unittest

class TestMathOperations(unittest.TestCase):
    def test_addition(self):
        self.assertEqual(1 + 1, 2)

    def test_subtraction(self):
        self.assertEqual(5 - 3, 2)

Each method in the class tests a specific functionality, and the test runner will execute all of them.

2. Use Setup and Teardown Methods

To reduce redundancy, use setUp() to prepare resources for each test and tearDown() to clean up afterwards. This ensures each test…
