Add comprehensive tests for formatter classes, services, and utilities
- Introduced tests for various formatter classes including TextFormatter, DurationFormatter, SizeFormatter, DateFormatter, and more to ensure correct formatting behavior. - Added tests for service classes such as FileTreeService, MetadataService, and RenameService, covering directory validation, metadata extraction, and file renaming functionalities. - Implemented utility tests for LanguageCodeExtractor, PatternExtractor, and FrameClassMatcher to validate their extraction and matching capabilities. - Updated test cases to use datasets for better maintainability and clarity. - Enhanced error handling tests to ensure robustness against missing or invalid data.
