TDD in Java Spring Boot Unit Testing Explained

Want to write bug-free Spring Boot code with confidence? In this video, you’ll learn Test-Driven Development (TDD) the practical way by building a real API and writing unit tests before the logic.

Instead of just explaining theory, we build a Discount Calculator API step-by-step using:

✅ Spring Boot
✅ JUnit 5
✅ Mockito
✅ Unit Testing Best Practices
✅ TDD Red → Green → Refactor Cycle

You’ll see how writing tests first helps you:

✔ Catch bugs early
✔ Design cleaner code
✔ Handle edge cases properly
✔ Build production-ready applications

By the end of this tutorial, you’ll understand how to apply TDD in real Spring Boot projects and feel confident writing testable code in Java.

This is perfect for:
• Java beginners
• Spring Boot developers
• Developers preparing for interviews
• Anyone wanting cleaner, safer code
