Unlock the Secrets of Test Driven Development (TDD)

Are you ready to dive deep into the world of Test Driven Development using Node.js, TypeScript, and Jest? This isn't just another course; it's a hands-on, practical exercise designed to immerse you in the TDD methodology. By the end of this session, you'll have a solid understanding of how to write effective tests first, before your code - a practice that will transform the way you approach software development. 🧪👨‍💻

Your Exercise: A Real-World TDD Challenge 🛍️

The Problem: You'll be tasked with creating a system that handles a shopping cart scenario, complete with item listings and a calculation for the final price, including discounts on certain products. This is not just about writing tests; it's about understanding how to apply TDD principles to ensure your solution is both efficient and maintainable.

Here's What You'll Learn:

• Understanding TDD: We'll kick things off by explaining the core concepts of Test Driven Development and why they matter.

• Setting Up Your Environment: Before we dive into coding, we'll make sure you have all the necessary tools installed - Node.js, TypeScript, and Jest.

• Writing Your First Tests: We'll guide you through writing your initial tests for the simplest functionality. This is where you'll learn to "Red" - recognize what needs to be done.

• Implementing Functionality: In the "Green" phase, you'll start coding to make your tests pass. This is where your coding skills will shine, and you'll see the power of writing code that's testable from the outset.

• Refactoring with Confidence: Finally, in the "Refactor" phase, you'll optimize your code, ensuring it's clean and efficient without changing its behavior - a critical TDD step that often gets overlooked. 🪨

The Iterative Approach: Red-Green-Refactor Loop 🔄

Throughout this exercise, you'll adhere to the disciplined red-green-refactor loop. This approach ensures you're always building with the least amount of code necessary, minimizing risk and complexity at every turn.

What's Next After This Kata? 🌟

After completing this exercise, you'll have a choice of three in-depth courses to further your knowledge:

1. Getting to Know TDD with Node, TypeScript, and Jest - If you're new to TDD, this is the perfect starting point.

2. Building a REST API using Outside-In TDD - For those looking to apply TDD principles specifically within RESTful application development.

3. Building a REST API using Inside-Out TDD - Ideal for developers who want to understand the benefits of starting with code before defining the API endpoints.
