Uses Playwright as a library within node:test (not @playwright/test) to
keep the same runner and script conventions. Browser test files use the
*.browser.ts extension so the existing src/**/*.test.ts glob picks up zero
browser tests, leaving the regular test suite unaffected.
Key pieces:
- .npmrc: PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 prevents binary downloads on
npm ci; browsers are installed explicitly in CI via playwright install
- @webnet/browser-test-utils: new private package exporting forBrowsers()
(iterates chromium + firefox, handles browser lifecycle within node:test
suite/before/after) and a serveDirectory() helper (minimal http.createServer
that serves a built dist/ or out/ directory so the browser can fetch ES
modules via dynamic import())
- test:browser / test:browser:coverage scripts added to transport, vfs,
tsconnect following the same c8 + lcov pattern as test:coverage
- turbo.json: test:browser and test:browser:coverage tasks depend on build +
^build (dist/ must exist before the browser can import from it)
- .gitea/workflows/test-browser.yml: CI pipeline that installs browsers with
--with-deps then runs npm run test:browser
Integration tests:
- DataChannelTransport: real RTCPeerConnection loopback (both peers in one
page context), exercises send/receive and close propagation
- FsaVFS: OPFS round-trip (writeFile/readFile), stat, readdir, delete
- IndexedDBState: multi-instance persistence (write via instance 1, open
fresh instance 2 and verify IDB round-trip), empty-DB initialisation
- FsaFileOps: write/read/stat/remove cycle and rename/listFiles over OPFS
