TDD Project: Building a Random Person Generator

Writing reliable software starts with testing, but writing tests after you write your code often leads to fragile designs. This text-based course guides you through the entire test-driven development (TDD) cycle—Red, Green, Refactor—by building a practical random person generator from scratch. During this hands-on project, you will learn how to approach software design from a test-first perspective, ensuring every line of code you write has a clear purpose and is fully verified. What you'll learn: - Understand the core principles of the Red-Green-Refactor cycle in TDD - Set up a modern testing environment using pytest and strict type hints - Write clear, failing tests first to define the behavior of your generator - Implement clean, minimal code to make your test suite pass successfully - Refactor your codebase with confidence knowing your tests protect against regressions - Handle edge cases, localized data, and randomized constraints systematically You will start with foundational TDD concepts and basic testing syntax before moving into the step-by-step implementation of the generator project, refining your code with every test. This course is perfect for beginner programmers who want to learn professional testing workflows. No prior testing experience is required. Start reading today to build stronger coding habits and write software that works every time.
