/playwright — Browser Runtime Tests
Core Rule
Use Playwright when the acceptance signal depends on a real browser: routing, forms, auth flows, rendering, navigation, API-backed UI state, responsive layouts, downloads/uploads, or regressions that unit tests cannot see.
For Athena v9.8.0, this skill is the frontend/E2E test arm of athena-runtime-verify. It complements the enabled playwright-skill@anthropic-official plugin and gives Athena-specific evidence rules.

Workflow
Detect project setup before adding anything:
- Existing Playwright: inspect
playwright.config.*, tests/, e2e/, package.json scripts.
- No Playwright: prefer adding
@playwright/test and a minimal config/test file that fits the repo.
- If the repo already uses Cypress/Vitest browser mode/etc., avoid wholesale migration; add Playwright only if runtime verification needs real browser coverage.
Start or reuse a deterministic app target:
- Prefer an existing dev/preview script from
package.json.
- Use a fixed port when possible.
- Set
baseURL in config or pass it via PLAYWRIGHT_BASE_URL.
- Do not leave background servers running at the end of the task.
Write tests through user-visible behavior:
- Use role/text/test-id locators instead of brittle CSS/XPath.
- Use Playwright web-first assertions such as
await expect(locator).toBeVisible().
- Keep tests small: one critical flow or acceptance behavior per test.
- Cover at least normal, boundary, and failure/empty states when doing
runtime-verify.
Run and iterate:
- Main path:
npx playwright test.
- Debug path:
npx playwright test --headed, npx playwright test --ui, or npx playwright codegen <url> when exploring selectors.
- Trace path:
npx playwright test --trace on then inspect with npx playwright show-trace <trace.zip>.
- If browser binaries are missing, run
npx playwright install or the narrower browser install requested by the repo.
Record evidence:
- Include exact command, exit code, and the important pass/fail output.
- For
athena-runtime-verify, write a row in runtime-verify.md with scenario, type, command, actual output, and verdict.
- If a test first fails and then passes after a fix, record both the failing symptom and the passing rerun.
Athena Integration
Feature: use when UI/API behavior is risky or user-visible.Refactor/System: use for browser-facing flows before review; this is part of runtime verification.Bugfix: use when the bug is reproducible in the browser, even though full runtime-verify is usually skipped.Hotfix/Quick: run only the smallest smoke path needed.
