From 9b802353eb5e2d071793b2a67b37a9db672304d5 Mon Sep 17 00:00:00 2001 From: xgopilot Date: Wed, 19 Nov 2025 06:33:15 +0000 Subject: [PATCH] test: add comprehensive unit tests and CI workflow - Set up Jest testing framework with TypeScript support - Add fake-indexeddb for database testing - Add test polyfills for TextEncoder, crypto.subtle, and structuredClone - Create comprehensive test suites: - utils/index.test.ts: 20 tests for hashing and URL utilities - database/index.test.ts: 26 tests for IndexedDB operations - export/zipExport.test.ts: 13 tests for ZIP export functionality - Add GitHub Actions workflow to run tests on CI - All 59 tests passing with coverage Generated with [codeagent](https://github.com/qbox/codeagent) Co-authored-by: minorcell
