Testing separates reliable applications from buggy disasters. Yet many developers struggle with Spring Boot testing - wrestling with complex dependency configurations, mocking external services, and writing tests that actually catch real problems.

Stop fighting your test suite and start building applications you can trust.

This book cuts through the confusion with practical, battle-tested strategies that work in real projects.

You'll discover how to write tests that catch bugs before they reach production, configure your testing environment without headaches, and build a comprehensive testing strategy that gives you genuine confidence in your code.

What you'll master:

• Unit testing that isolates components effectively
• Sliced testing for fast and isolated tests
• Test configuration that doesn't break every deployment
• Integration testing that reveals system-level issues

Whether you're debugging flaky tests or building your first Spring Boot application, this guide transforms testing from a necessary evil into your competitive advantage. Each chapter includes working examples you can implement immediately, plus common pitfalls to avoid.
