Testing — Q-Edit

Stack

• Vitest with jsdom for DOM-related tests.
• Coverage via v8 with thresholds Lines 70 / Branches 70 / Functions 50 / Statements 70.

Conventions

• Place tests under tests/ with suffix .test.mjs or .spec.mjs.
• Keep tests deterministic; avoid real sleeps. For pure utils, test inputs/outputs.
• For DOM tests, load index.html and assert on key elements (smoke tests).

Commands

• npm test — run once with coverage
• npm run test:watch — watch mode

Roadmap

• As we extract modules from script.js, add unit tests per module.
• Later: E2E with Playwright (mock network via MSW).
