In Flask, you can perform unit testing using the unittest module . This module is included by default when you install Flask, making it easily accessible for testing purposes. The unittest module provides various methods that enable you to test the functionality of your code. Some of the commonly used methods include assertEqual() , assertTrue() , assertFalse() , and assertRaises() . These methods allow you to compare expected and actual results, ensuring that your code behaves as intended. To illustrate how unit testing works in Flask, let's consider an example. Suppose you have a module that contains math functions, such as addition and multiplication. Using the unittest module , you can write test cases for these functions to verify their correctness. By comparing the expected output with the actual output, you can easily identify any discrepancies and fix them before deploying your code. Example Code: import unittest def add(a, b): return a + b class MathFunctionsTestCase(unittest.TestCase): def test_addition(self): result = add(2, 3) self.assertEqual(result, 5) def test_multiplication(self): result = multiply(2, 3) self.assertEqual(result, 6) if __name__ == '__main__': unittest.main() In the example code above, we define a test case class called MathFunctionsTestCase that inherits from unittest.TestCase . Within this class, we define individual test methods, such as test_addition() and test_multiplication() , which test the add() and multiply() functions respectively. By

running the unittest.main() function, we execute the test cases and check if the expected results match the actual results. By incorporating unit testing into your Flask development process, you can ensure the functionality and reliability of your code. Writing test cases using the unittest module helps catch bugs early, reduces the likelihood of introducing new issues, and promotes code quality and maintainability.
