Use when the user wants browser UI e2e as a Playwright Test spec — converting a completed cuawright-web run, or unblocking a missing Playwright toolchain or cuawright-web run first. Not for API-level end-to-end tests.

“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Write E2E Tests

Turns a browser UI flow into a checked-in Playwright Test spec. CUAWright is the exploration engine: it produces plan.md and final_script.py. This skill unblocks a missing toolchain or run after confirmation, then converts.

Scope

The output is always a Playwright Test spec — no per-project detection of another framework, no cross-framework translation. An existing Cypress or Selenium suite stays; confirm before adding Playwright beside it.

Workflow

  1. Inventory. In the target project, mark each of these present or absent: a JS package manifest and its package manager; @playwright/test and playwright.config; the cuawright-web skill; a qualifying run; another e2e stack (Cypress, Selenium); existing CI files; cuawright-web artifact paths git still tracks. CUAWright is present when the session's skill list names cuawright-web (or legacy webwright), bare or plugin-prefixed. Leave this step when every item is marked. No package manifest — stop and report.
  2. Toolchain. If Playwright, browsers, or cuawright-web are missing, confirm once for those items and follow references/setup.md. Another e2e stack without Playwright — confirm adding Playwright beside it.
  3. Find a qualifying run. Search outputs/, final_runs/, and any path the user named for plan.md plus final_script.py whose Critical Points are all checked. Found — show the path and reuse it unless the user asks to re-run. Otherwise go to explore.
  4. Explore. Confirm on its own before driving the real site. If the user has not named the flow, ask. Invoke the cuawright-web skill with the target browser (default Chromium, e.g. playwright.chromium) and run it to Done. Leave this step when cuawright-web reports Done and a qualifying run from step 3 is on disk. Reading source is not Explore. Convert is the next step. Exploration stays in cuawright-web.
  5. Repo — gitignore. Propose .gitignore rules when unignored cuawright-web artifacts exist (outputs/, final_runs/, screenshots/logs) or this run just scaffolded Playwright (test-results/, playwright-report/). Write only after confirmation. Add rules only; do not git rm --cached already-tracked files.
  6. Convert. Start only when step 3's plan.md and final_script.py exist; missing — return to Explore. How to handle a scan hit is in references/security.md.
    • Scan input. Run scripts/scan-secrets.sh on final_script.py. Non-zero exit: follow that doc. A visual read of the script is not a scan. Draft only after the scan exits 0, or after every hit has a confirmed process.env mapping.
    • Map and draft. Map each Critical Point in plan.md one-to-one to an expect() assertion; that mapping is the whole of the conversion. Use final_script.py for selectors and action order only. Write credential fields as process.env names; leave selectors and non-credential fixtures as literals. Never emit static delays (page.waitForTimeout() or time.sleep conversions) — use event-driven waits (expect(locator).toBeVisible(), waitForLoadState('domcontentloaded'), or waitForResponse()). Check optional dialogues (tours, cookie banners) with immediate await locator.isVisible() rather than blocking waitFor. Reuse authenticated sessions via storageState or API requests (request.post), avoiding repeated UI login form submissions in beforeEach unless testing auth itself. For tests mutating shared database or server state, isolate with { lock: '-exclusive-' } rather than disabling fullyParallel across the entire suite.
    • Scan output. Run scripts/scan-secrets.sh on the drafted spec before writing it. Non-zero exit: follow that doc. Write only a spec the script accepts. Place the spec in the project's existing e2e test directory (its Playwright config's testDir, or the project's established convention), named after the flow being converted.
  7. Validate. Run all three gates, in order:
    • Run — execute the generated spec once; it passes.
    • Stable — re-run it 3 consecutive times; all 3 pass.
    • Discoverable — the project's test-run command finds the new spec file. A remote pipeline is not required. On failure, attempt an automatic fix and re-validate, up to 2 attempts. Still failing after that — stop and report. Hand back only a spec that has passed all three gates.
  8. Repo — CI. After Validate, follow references/ci.md. Write only after confirmation.
