SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Verifies role-based access control and authorization policies using Spring Security test utilities.

Core Features & Use Cases

Validate @PreAuthorize, @Secured, and custom permission evaluators.
Confirm access denied scenarios for unauthorized users.
Mock authenticated principals in controller and service tests.

Quick Start

Write tests with @WithMockUser or programmatic authentication to exercise secured methods and endpoints.

FAQPage Schema

How do I test Spring Security authorization with @PreAuthorize annotations?▼

Test @PreAuthorize authorization by writing unit tests with @WithMockUser to mock authenticated principals, then assert that secured methods grant or deny access based on roles. MockMvc and spring-security-test handle authentication context injection for controller and service-layer tests.

Can I verify role-based access control (RBAC) policies in unit tests?▼

Yes. Use spring-security-test with JUnit 5 to validate RBAC policies by mocking users with specific roles, then confirm @PreAuthorize, @Secured, and @RolesAllowed annotations enforce correct access decisions for admin, user, and anonymous scenarios.

What's the best way to test denied-access scenarios in Spring Security?▼

Write tests that execute secured endpoints or methods with insufficient roles and assert AccessDeniedException or HTTP 403 responses. Spring Security test utilities and MockMvc capture authorization failures without requiring live authentication.

How do I set up dependencies for Spring Security unit testing?▼

Add spring-boot-starter-security, spring-boot-starter-test, and spring-security-test to your project. These provide MockMvc, @WithMockUser, and authentication mocking required for testing @PreAuthorize and custom permission evaluators in unit tests.

Do custom permission evaluators work with MockMvc testing?▼

Yes. MockMvc supports testing custom permission evaluators by injecting mocked authentication principals with @WithMockUser or programmatic SecurityContext setup, allowing you to verify custom authorization logic alongside standard RBAC policies.

Why test authorization at the unit level instead of integration tests?▼

Unit tests with MockMvc isolate authorization logic from the full application stack, execute faster, and let you validate specific role and permission combinations. Spring Security test utilities mock authentication context without requiring a running server.
