Testing Data Permission Context Management in ruoyi-vue-pro

This test suite validates the DataPermissionContextHolder class functionality, focusing on managing data permission contexts in a thread-safe manner. The tests ensure proper handling of permission stacks and context management operations.

Test Coverage Overview

The test suite provides comprehensive coverage of DataPermissionContextHolder operations:

Stack-based permission context management
Context addition and removal operations
Thread-local storage verification
Multiple permission context handling

Implementation Analysis

The testing approach utilizes JUnit 5 with Mockito for dependency isolation. Each test case focuses on specific context holder operations, employing a clear arrange-act-assert pattern with mock DataPermission objects.

Key patterns include context stack manipulation, clean state verification, and thread-local storage management.

Technical Details

Testing infrastructure includes:

JUnit Jupiter for test execution
Mockito framework for mocking
BeforeEach setup for test isolation
Assert methods for verification
Thread-local context management utilities

Best Practices Demonstrated

The test suite exemplifies several testing best practices:

Proper test isolation through setUp method
Clear test method naming conventions
Comprehensive assertion coverage
Effective use of mocking
Clean state management between tests
