Oct 27, 2022 · You'll learn how to use Python's built-in unittest module to set up and run unit tests and write test cases to test Python functions. You'll also learn how to test functions that raise exceptions. Let's get started! We'll start by defining a Python function and write unit tests to check if it works as expected.

May 1, 2024 · Python Unit testing is a software testing technique where individual units or components of a software application are tested in isolation from the rest of the system. The primary goal of Python unit testing is checking the validation that each unit of the software performs as designed, according to its specifications.

Apr 8, 2025 · In this article, we'll cover the writing of unit tests in Python, from understanding the assert statement to using a framework designed specifically for this kind of task — and following Python unit testing best practices. Python has two main frameworks to make unit testing easier: unittest and PyTest.

May 31, 2024 · In Python, the unittest module provides a strong framework for writing and running tests. This article will guide you through the best practices for writing and running unit tests using the...

Summary: in this tutorial, you’ll learn about the unit test concept and how to use the Python unittest module to perform unit testing. A unit test is an automated test that: Verifies a small piece of code called a unit. A unit can be a function or a method of a class. Runs very fast. Executes in an isolated manner.

Feb 25, 2025 · This example demonstrates a basic unit test using the unittest module. The class MyTestCase inherits from unittest.TestCase, defining a single test method, test_basic_arithmetic. This method uses assertEqual to verify that 1 + 1 equals 2. When executed via unittest.main(), the test runner checks this assertion and reports the result.
