Foundations of Test Driven Development with Python

Software development often feels like a race against bugs, but there is a more structured way to build reliable applications. Test Driven Development (TDD) shifts the focus from fixing errors to preventing them through a disciplined, design-first approach. You will move from writing code and hoping it works to building software with the confidence that every feature is verified by a suite of automated tests. By adopting this workflow, you improve code quality, simplify maintenance, and create a robust safety net for future changes. What you'll learn: - Understand the fundamental principles and terminology of the TDD workflow - Apply the Red-Green-Refactor cycle to solve programming challenges - Practice writing effective unit tests using the Pytest framework - Master the art of refactoring code while maintaining full test coverage - Learn how to isolate components using modern mocking and dependency injection patterns - Identify when to use TDD and how to integrate it into a professional development environment The course begins with core definitions and the philosophy behind testing before guiding you through written explanations and code-based scenarios. You will explore how to structure tests, handle edge cases, and maintain a clean codebase as your project grows through structured reading and logic exercises. This course is designed for beginner-to-intermediate developers who have a basic understanding of Python and want to adopt professional software engineering practices. No prior experience with automated testing is required. Start reading to transform how you approach software design and code reliability.
