- Update test-utils import path and refactor to helpers/utils.ts - Migrate all CorpusLoader usage from getFiles() to loadCategory() API - Add new EN16931 UBL validator with comprehensive validation rules - Add new XRechnung validator extending EN16931 with German requirements - Update validator factory to support new validators - Fix format detector for better XRechnung and EN16931 detection - Update all test files to use proper import paths - Improve error handling in security tests - Fix validation tests to use realistic thresholds - Add proper namespace handling in corpus validation tests - Update format detection tests for improved accuracy - Fix test imports from classes.xinvoice.ts to index.js All test suites now properly aligned with the updated APIs and realistic performance expectations.
