Playwright UX/UI Capture (Artifact-first)

When to use

Use this skill when implementing or modifying Playwright E2E to:

• capture screenshots for a set of routes
• emit per-route artifacts immediately to disk
• keep the process robust and deterministic

Repo conventions

• Playwright config: edgequake_webui/playwright.config.ts
• Tests live in: edgequake_webui/e2e/
• UX/UI output dir: ux_ui_map/ (repo root)

Route discovery

Prefer enumerating concrete page.tsx files under edgequake_webui/src/app/**/page.tsx.

• Ignore route groups: folders like (dashboard) do not appear in URL paths.
• Avoid dynamic segments: paths with [param], [...param], [[...param]] are not capturable without fixture data.

Helper script (no dependencies):

• Derive concrete routes from the Next.js App Router: scripts/derive_routes.mjs

Example:

node .github/skills/playwright-ux-ui-capture/scripts/derive_routes.mjs --format json

Viewports (required)

Capture exactly these 3 widths (use a reasonable height):

• desktop: 1440px
• tablet: 768px
• mobile: 375px

Waiting strategy (important)

• Prefer Playwright auto-waits + a stable “page ready” signal (e.g. a visible main or h1).
• Avoid relying on waitForLoadState('networkidle') as the primary sync.

Artifact write-out (must be immediate)

For each route:

1. create ux_ui_map/screenshots/{page}/
2. write desktop.png, tablet.png, mobile.png
3. write/update ux_ui_map/requests/{page}.json from the template
4. append one JSON line to ux_ui_map/capture-index.jsonl

How to run

From repo root:

• cd edgequake_webui && npm run test:e2e

To run a single spec (preferred while iterating):

• cd edgequake_webui && npx playwright test e2e/<spec>.spec.ts

Output example (capture index)

Each line is a standalone JSON object:

{"page":"dashboard","route":"/","capturedAt":"2025-12-26T12:34:56.000Z","ok":true}

Common failure handling

• If a page requires auth, capture /login first and then attempt the route.
• If a route 404s, still write a capture-index line with ok:false and store a screenshot of the error state.
