# 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).
