Java testing helps you catch bugs before your code goes live. You write small checks called unit tests with JUnit 5. You can fake parts of your application using Mockito to test each piece alone.
Integration tests make sure your app works with a real database or web server. Tools like Testcontainers spin up temporary databases for testing. You can also test your API endpoints with MockMvc.
Using test‑driven development or TDD means you write tests first to guide your code. This skill gives you the patterns and examples to build reliable Java applications.
