From 1084931b227448aa55113ffb2077f531345280b7 Mon Sep 17 00:00:00 2001 From: shrimbly Date: Tue, 13 Jan 2026 10:03:33 +1300 Subject: [PATCH] test(17-04): add AnnotationNode component tests - Basic rendering with title and handles (image input/output) - Empty state with "Drop, click, or connect" message - Image display (sourceImage, outputImage, priority logic) - Edit overlay with annotation count display - Modal opening via image click with existing annotations - Remove button clearing all image data and annotations - File upload with format/size validation (PNG, JPG, WebP; <10MB) - Drag and drop handling - Custom title editing functionality Note: Tests focus on component shell and state management, not internal Konva canvas interactions per plan guidance.
