Automated Testing with Python unittest

Writing reliable software requires a solid testing strategy, yet many developers struggle with where to begin. This text-based course guides you through Python's built-in unittest module, showing you how to write automated tests that catch bugs before they reach production. You will transform your development process by learning how to structure, run, and maintain a robust suite of tests. What you will learn: Understand the core principles of unit testing and test-driven development; Configure test cases, test suites, and test runners using the unittest module; Manage setup and teardown processes with fixtures to keep your tests clean; Apply mocking techniques to isolate your code from external dependencies; Practice modern testing workflows including basic testing with pytest for broader compatibility. We begin with foundational testing concepts and essential terminology, then progress step-by-step through writing your first assertions, organizing test suites, and utilizing advanced isolation techniques. This course is designed for beginner Python developers and those new to automated testing, requiring only a basic understanding of Python syntax. Take your first step toward writing bulletproof Python code today.
