Milestone 6: Testing & Quality

🧪 Milestone 6: Testing & Quality

Welcome to the quality assurance layer. Here, we learn how to write professional tests that ensure our application is bug-free and maintainable for years to come.

📚 Slow-Paced Deep Dives

• Module 1: Unit Testing with JUnit 5 (Testing the Bolt): Testing small, individual methods in isolation.
• Module 2: Mockito (The Stunt Double): Creating fake objects to simulate external systems.

2. Use Assertions to verify expected vs actual results.
3. Mock a Repository to test a Service without a real database.
4. Understand the difference between Unit and Integration tests.
