Does this skill support the latest Spring Boot versions?

Yes, it utilizes modern Spring Boot testing patterns including JUnit 5, MockitoExtension, and fluent MockMvc assertions.

How does this skill handle localized error messages?

It provides templates for injecting mocked MessageService or MessageSource beans into the ExceptionHandler, allowing you to verify that the correct localization keys are requested based on the exception context.

Why test exception handlers in isolation rather than full integration tests?

Testing in a standalone MockMvc setup is significantly faster than starting a full application context while still accurately verifying the mapping between Java exceptions and HTTP responses.

Can I test validation errors for REST controllers?

Absolutely. This skill includes specific patterns for capturing and asserting against MethodArgumentNotValidException and field-level binding errors.

安全与测试

Streamlines the creation of unit tests for Spring Boot @ControllerAdvice and @ExceptionHandler components using MockMvc.

关于

This skill provides specialized implementation patterns for unit testing global exception handling logic in Spring Boot applications. It allows developers to rigorously verify HTTP status codes, error response DTO structures, and exception-to-response mapping using MockMvc in a standalone configuration. By focusing on the transformation layer, it ensures that your API provides consistent, well-formatted error messages to consumers without the overhead of a full integration test suite.
