Testing Admin User Service Implementation in RuoYi Vue Pro

A comprehensive unit test suite for AdminUserServiceImpl class that verifies user management functionality including CRUD operations, password updates, profile management, and import/export features. The tests ensure proper handling of user data, permissions, and integration with related services.
Test Coverage Overview

The test suite provides extensive coverage of user management operations including:
User creation, update and deletion flows
Password management and validation
Profile updates including avatar handling
User search and filtering capabilities
Import/export functionality with validation
Edge cases around permissions and status changes
Implementation Analysis

The implementation uses JUnit 5 with Mockito for mocking dependencies. Key patterns include:
Base test class inheritance for DB operations
Extensive use of mock objects for external services
Helper methods for test data generation
Validation of business rules and constraints
Technical Details

Testing tools and configuration:
JUnit 5 test framework
Mockito for mocking
Spring Boot Test for DI and configuration
In-memory H2 database
Custom test utilities for assertions
Best Practices Demonstrated

The test suite demonstrates several testing best practices:
Thorough setup and teardown of test data
Isolation of test cases
Comprehensive assertion of outcomes
Clear test naming and organization
Proper exception handling verification
