Test only

[Copilot]

This PR adds a comprehensive analysis of test files in the repository to identify violations of the YAGNI (You Ain't Gonna Need It) principle. The analysis examines test code for over-engineering, excessive complexity, and premature optimization that may be hindering maintainability.

Analysis Summary

The report YAGNI_ANALYSIS_REPORT.md identifies seven key areas where test code violates YAGNI principles:

Key Findings

1. Excessive Version Directive Testing - The testexcludedfiles.cpp contains 14 test cases for simple version comparisons that could be reduced to 4-6 essential cases
2. Premature Performance Benchmarks - Performance tests using QBENCHMARK were added without evidence of performance issues
3. Over-Engineered Test Data - Complex test fixtures with translation scenarios and date calculations that exceed current requirements
4. Complex Windows LNK Testing - Extensive COM interface manipulation for file handling that could be simplified
5. Redundant File System Validation - Testing multiple APIs for the same metadata when one would suffice
6. Over-Complex Test Helpers - Detailed nested structures in test utilities that are more complex than needed
7. Unused Parameters - Methods with Q_UNUSED parameters indicating premature interface design

Impact

These violations lead to:

• Increased maintenance burden
• Longer test execution times
• Code complexity that obscures actual requirements
• Premature abstractions that may not align with future needs

Recommendations

The report provides specific code examples and suggests improvements such as:

• Simplifying test fixtures to match actual requirements
• Removing performance tests until performance issues are identified
• Eliminating unused code and parameters
• Focusing on business logic rather than API consistency testing

This analysis will help guide future refactoring efforts to create more maintainable and focused test code that adheres to YAGNI principles.
