description	Generate Spring MVC controller tests using `@WebMvcTest` and `MockMvc` for focused REST endpoint validation without booting the full application context.

Spring MVC Controller Test Generator

Generate focused unit tests for Spring REST controllers using @WebMvcTest.

Required inputs

• Controller class under test
• DTO request/response classes and sample fixture data
• Service dependencies and their method signatures
• Expected HTTP responses and error conditions

Workflow

1. Read references/implementation.md.
2. If fixing or reviewing existing tests, also read references/review.md.
3. Create fixture DTOs with realistic field values.
4. Mock the service layer dependencies with @MockBean.
5. Use MockMvc to test endpoints, verifying status codes and response bodies.

Output contract

• Output one compilable @WebMvcTest test class.
• Keep tests focused on endpoint behavior and HTTP contracts.
• Use @WebMvcTest only; do not load the full Spring context.
• Tests should cover happy path, edge cases, and error scenarios.

Reference files

• references/implementation.md: @WebMvcTest generation rules.
• references/review.md: MVC test review checklist.
