What you'll learn

Without proper testing and exception handling, Spring applications can fail unpredictably in production, leaving you without a reliable way to detect, diagnose, or prevent issues. In this course, Testing and Exception Handling in Spring Framework 7, you’ll gain the ability to build resilient Spring applications through effective testing strategies and centralized error handling. First, you’ll explore the differences between unit testing and Spring integration testing, along with the key libraries used to implement them. Next, you’ll learn how to write effective unit tests using JUnit and Mockito to validate business logic and service-layer components. Finally, you’ll discover how to create comprehensive Spring integration tests and implement centralized exception handling and input validation across your applications. When you’re finished with this course, you’ll have the skills and knowledge of Spring testing and exception handling needed to build stable, maintainable, and production-ready applications.
