First frontend unit test framework on Lumotia. Pinned exact versions for supply-chain hygiene (matches the rust-toolchain.toml discipline from the27661c8hygiene pass and the npm audit signatures pre-flight frome4d56b8): - vitest 4.1.6 (compatible with vite 6, supports vite 6/7/8) - jsdom 29.1.1 Installed with `npm install --save-dev --save-exact --ignore-scripts` per the install discipline documented in the README — the --ignore-scripts flag blocks the postinstall vector that npm worms (Shai-Hulud, mini-Shai-Hulud) rely on. vite.config.js: - Switched defineConfig import to vitest/config (superset of vite/config; production builds ignore the `test` key). - test.environment = "jsdom" so storage-shim tests drive real browser APIs. - test.include scoped to src/**/*.{test,spec}.{ts,js} — colocated with source, mirrors the Rust #[cfg(test)] sibling pattern. - test.exclude blocks src-tauri/ (owned by cargo test). - restoreMocks + clearMocks + unstubAllGlobals on so module-level state can't leak between tests. src/lib/utils/localStorageMigration.test.ts — 12 tests: migrateLocalStorageKey: - copies value + removes old when only old exists - removes old + keeps new when both exist (lumotia is authoritative) - no-op when only new exists - no-op when neither exists - idempotent (second call after first migrates nothing) - preserves the value's exact bytes (no JSON round-trip) - preserves empty-string values (distinct from null) - survives DOMException / quota errors without re-raising - no-op when localStorage is undefined (SSR-safe) migrateLocalStorageKeys: - processes pairs in order - per-pair failure does not strand remaining pairs (resilience) - empty pairs list is a clean no-op package.json: - "test": "vitest run" (one-shot, CI-friendly) - "test:watch": "vitest" (dev loop) README: documents `npm run test` alongside `cargo test --workspace` and `npm run check` in the Testing section. Verification: - npm run test: 12/12 pass - npm run check: 0 errors, 0 warnings (the new .ts test type-checks clean against jsconfig.json's strict typescript settings)
