unit-test-exception-handler

This skill provides patterns for unit testing @ExceptionHandler methods and @ControllerAdvice classes using MockMvc. It covers testing exception-to-error-response transformations, HTTP status codes, error message formatting, validation error handling, and custom permission evaluators without full integration test overhead.

Exception handler not invoked: Ensure controller is registered with MockMvc and actually throws the exception.

JsonPath matchers not matching: Use .andDo(print()) to see actual response structure.

提供单元测试 @ExceptionHandler 和 @ControllerAdvice 的模式以进行全局异常处理。在验证错误响应格式和 HTTP 状态代码时使用。 来源：giuseppe-trisciuoglio/developer-kit。
