Does this skill support JUnit 5?

Yes, it is fully optimized for JUnit 5 and integrates seamlessly with the Spring Boot Test framework.

Does this require a running database or server?

No, these patterns focus on unit and slice testing, allowing you to verify security logic quickly by mocking dependencies and avoiding full infrastructure setup.

Can I test custom permission evaluators?

Absolutely; the skill provides patterns for testing custom PermissionEvaluator implementations by mocking the Authentication and target objects.

Is it compatible with legacy Spring Security configurations?

Yes, the skill includes guidance for both modern expression-based @PreAuthorize and legacy @Secured or @RolesAllowed annotations.

How do I simulate specific user roles in tests?

You can use the @WithMockUser annotation to define roles, usernames, and authorities, or use SecurityMockMvcRequestPostProcessors within MockMvc calls.

Seguridad y Pruebas

Tests Spring Security authorization logic including role-based access control and method-level security annotations.

This skill provides specialized guidance and implementation patterns for verifying security constraints in Spring Boot applications using JUnit 5. It enables developers to rigorously test @PreAuthorize and @Secured annotations, simulate authenticated principals with @WithMockUser, and validate custom PermissionEvaluator logic. By focusing on fast-executing unit and slice tests, this skill helps ensure that access control policies are correctly enforced across services and controllers without the overhead of a full security infrastructure.
