What dependencies are required to use these patterns?

These patterns require the Spring Boot Starter Test and Mockito libraries, which are standard components in most Spring Boot projects.

Can I test global exception handling with this skill?

Yes, the skill includes patterns for verifying that your @ControllerAdvice or specific exception handlers return the correct HTTP status codes and error payloads.

What is the primary benefit of using MockMvc for controller tests?

MockMvc allows you to test the web layer in isolation without starting a full HTTP server, making tests significantly faster and more focused on request/response logic.

Does this skill support complex JSON response validation?

Absolutely, it provides detailed examples using JsonPath to verify nested fields, arrays, and specific values within the returned JSON body.

セキュリティとテスト

Streamlines Java REST controller testing by providing MockMvc patterns and best practices for isolated web layer validation.

概要

This skill provides a standardized framework for testing Spring Boot @RestController and @Controller classes using MockMvc and Mockito. It enables developers to verify HTTP status codes, response formats, request parameter binding, and exception handling in isolation without the overhead of a full application context. Ideal for maintaining robust API contracts, the skill includes comprehensive implementation patterns for GET, POST, PUT, and DELETE operations, ensuring fast and reliable testing of the web layer.
