SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Security and authorization testing for Spring components, enabling reliable RBAC verification without full security context.

Core Features & Use Cases

Pattern-based testing for @PreAuthorize, @Secured, @RolesAllowed
Mocking with WithMockUser; test allow/deny; test expression-based and custom permission evaluators; test controllers with MockMvc
Use cases: unit tests for security constraints, integration with RBAC.

Quick Start

Add a test with @WithMockUser(roles = 'ADMIN') to verify an admin can access a secured method and a test with @WithMockUser(roles = 'USER') to verify access is denied.

FAQPage Schema

How do I unit test Spring Security authorization rules like @PreAuthorize and @Secured?▼

Unit testing Spring Security authorization rules involves using Spring Security Test with JUnit 5 to validate @PreAuthorize, @Secured, and @RolesAllowed annotations. You mock authentication contexts using @WithMockUser to verify both allowed and denied access across service methods and REST endpoints.

How does @WithMockUser work for testing RBAC permissions?▼

@WithMockUser works for testing RBAC permissions by injecting a mock authentication object into the Spring Security context during test execution. It allows simulating specific user roles like ADMIN or USER to verify that expression-based access control and custom PermissionEvaluators correctly allow or deny method access.

Can I test custom PermissionEvaluators in Spring Security without a full security context?▼

Yes, you can test custom PermissionEvaluators without a full security context by isolating business logic and mocking external dependencies. Using @WithMockUser or custom authentication objects, you validate expression-based access control rules in RBAC scenarios across service methods and REST controller endpoints.

Do I need Spring Security Test and JUnit 5 to test @PreAuthorize expressions?▼

Yes, you need Spring Security Test and JUnit 5 to test @PreAuthorize expressions effectively. These frameworks provide the necessary annotations and mock authentication utilities required to simulate user roles and verify both allowed and denied access to secured service methods and REST endpoints.

What is the best way to test both allowed and denied access in Spring Security RBAC scenarios?▼

The best way to test allowed and denied access in Spring Security RBAC scenarios is to use pattern-based testing with @WithMockUser. By simulating different roles like ADMIN and USER, you verify expression-based access control and custom PermissionEvaluators across both service and controller layers.
