From a2424bcf743435876a0cf9fe54340fe7efc03b2c Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Fri, 30 Jan 2026 16:13:10 -0500 Subject: [PATCH] Phase 1 Week 4: Testing & Validation - Create comprehensive unit tests for sync package - format_test.go: 60+ tests for format detection - EPUB format detection (mimetype, extension, uppercase) - MOBI/AZW3/FB2/TXT reflowable formats - PDF/DJVU fixed layout formats - CBZ/CBR/CB7/CBT comic archive formats - Unknown format handling - MimeType lookup tests - IsReflowable/HasFixedLayout/IsComicArchive helpers - progress_test.go: 45+ tests for progress conversion - PageToPercentage/PercentageToPage (with clamping) - CharacterToPercentage/PercentageToCharacter - ConvertProgress between format groups - MergeProgress with 'max progress wins' strategy - FormatProgressForDisplay for UI rendering - Round-trip conversion tests - Edge cases (very small/large values, floating point precision) - All tests pass successfully - Test coverage: format detection, progress conversion, display formatting - Validates Phase 1 implementation quality --- internal/sync/format_test.go | 263 +++++++++++++++++++ internal/sync/progress_test.go | 458
