Author the Playwright fixture layer every Chromium extension test depends on - `chromium.launchPersistentContext` with `--disable-extensions-except=$DIR` + `--load-extension=$DIR`, the `channel: 'chromium'` selection that unlocks headless extension support, the `context.serviceWorkers()` + `waitForEvent('serviceworker')` race-handling pattern, and the `extensionId = serviceWorker.url().split('/')[2]` extraction recipe - plus, in references/, the extension load / reload matrix…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# playwright-extension-fixtures ## Overview Every Playwright-driven Chromium-extension test starts the same way: a persistent context launched with two flags, a service-worker race, and an extension-ID extraction. Per the [Playwright Chrome extensions docs][pw-ext], this fixture is the contract the assertion-level skills depend on - it's the foundation, not the test logic. This SKILL.md is the "how to launch" layer - the Playwright fixture pattern (`launchPersistentContext` + `--disable-extensions-except` + `--load-extension`) shared by all extension tests. The "what to assert" playbook per surface - popup, content script, background messaging, storage, MV3 auto-suspend - lives in [references/extension-surface-tests.md](references/extension-surface-tests.md) and builds on this fixture. [pw-ext]: https://playwright.dev/docs/chrome-extensions Composes with: - [references/extension-surface-tests.md](references/extension-surface-tests.md) - per-surface assertion recipes (popup, content script, messaging, storage persistence, auto-suspend) run from this fixture. …

How to install
mdr add testland/qa/playwright-extension-fixtures@sha256:e5f5a8aa46d420d3The line at the top of this page pins the label v1.2.7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
