Unit test Spring Security @PreAuthorize annotations by combining JUnit with @WithMockUser to simulate specific roles and verify access control logic. This validates that only authorized users can execute secured methods or access API endpoints.

The best way to test role-based access control in a Spring Boot application is to write JUnit tests covering @Secured and @RolesAllowed annotations. Simulating different user roles verifies that your authorization policies correctly restrict sensitive actions.

Test Spring Security expression-based security and custom PermissionEvaluators by writing integration tests that validate custom security expressions. This ensures your complex permission evaluation logic robustly authorizes user actions before execution.

Yes, you can use MockMvc to test controller-level security in Spring Security. By combining MockMvc with @WithMockUser, you can validate secured endpoints and ensure your API correctly enforces authorization policies for different user roles.

Yes, this testing approach supports comprehensive integration testing for both @PreAuthorize and @Secured annotations. It facilitates validating role-based access control and expression-based security across your Java application's authorization mechanisms.
