Test Architecture

All tests follow a consistent structure:

• Comprehensive mocking of dependencies
• Clear test class organization by functionality
• Descriptive test method names
• Proper fixture setup and teardown
• Error scenario coverage
• Performance considerations

Next Steps

1. Integration Tests: Cross-service interaction testing
2. End-to-End Tests: Complete workflow validation
3. Performance Tests: Load and stress testing
4. Security Tests: Security vulnerability assessment
