# Testing
|
|
|
|
We run Vitest in browser mode using Playwright (Chromium) with `vitest-browser-vue` to mount Vue components.
|
|
|
|
- Global setup: see `tests/setup.ts` (mocks `echarts/core`, resets DOM after each test).
|
|
- Prefer shared helpers under `tests/helpers/` to avoid duplicated setup.
|
|
- Test only public behavior; avoid internal implementation details.
|
|
- Keep tests deterministic: silence console noise and flush updates/animation frames with provided helpers.
|
|
|
|
## Run locally
|
|
|
|
- Install dependencies: `pnpm install`
|
|
- Install Chromium: `pnpm test:setup`
|
|
- Run tests: `pnpm test`
|
|
- Coverage (V8): `pnpm test:coverage`
|
|
- HTML report: `coverage/browser/index.html`
|
|
- LCOV: `coverage/browser/lcov.info`
|
|
|
|
## CI
|
|
|
|
- CI runs tests with coverage and uploads LCOV to Codecov (non-blocking).
|
|
- Chromium is installed via Playwright CLI with system deps: `pnpm exec playwright install --with-deps chromium`.
|
|
- Optional: restrict Codecov uploads to PRs and `main` via a workflow condition.
