**Current Status**: 91 of 144 planned tests implemented (~63% complete). Core functionality now comprehensively tested across format detection, validation, PDF operations, format conversion, error handling, XML parsing, and encoding. The test suite provides robust coverage of production-critical features with real-world corpus integration, performance tracking, and comprehensive error analysis. Full documentation available in [test/readme.md](test/readme.md).
**Current Status**: 117 of 144 planned tests implemented (~81% complete). Core functionality now comprehensively tested across format detection, validation, PDF operations, format conversion, error handling, XML parsing, encoding, performance, security, edge cases, and major standards compliance including European and Italian requirements. The test suite provides robust coverage of production-critical features with real-world corpus integration, performance tracking, and comprehensive error analysis.
