Webapp Testing Playwright
Webapp Testing Playwright is an design AI skill with a core value of End-to-end visual testing suite. It
helps developers solve real-world problems in the design domain, boosting
efficiency, automating repetitive tasks, and optimizing workflows.
End-to-end visual testing suite. Agents write and execute their own browser tests to verify UI changes.

# 2.5.2 Webapp Testing Playwright
When verifying web UI changes, implement and execute end-to-end tests using Playwright to ensure regressions are caught automatically.
1. Test Architecture
- **Location:** Keep E2E tests in a dedicated folder (e.g., `tests/e2e/` or `e2e/`).
- **Isolation:** Each test should set up its own isolated state via fixtures to prevent dependencies between test runs.
2. Locators and Interactions
- **User-Centric Locators:** Always prefer testing the UI the way a user interacts with it. Use `getByRole`, `getByText`, or `getByLabel` instead of brittle CSS selectors or XPaths.
- **Awaits:** Trust Playwright's auto-waiting logic. Do not use hardcoded `page.waitForTimeout` unless absolutely necessary for external animations that cannot be hooked.
3. Authentication & State
- **Storage State:** For tests requiring login, authenticate once in a global setup and reuse the storage state (cookies/origins) across the test suite to save time.
4. Visual Testing (Optional)
- **Snapshots:** Use `expect(page).toHaveScreenshot()` when layout drift needs to be strictly monitored. Ensure these are run in consistent environments (like Docker) to avoid OS-level rendering diffs.

⚠️ Common Mistakes to Avoid
Not testing edge cases
AI tends to generate happy-path tests. Manually review for boundary conditions.
Skipping usability testing
AI-generated designs should be validated with real users before development.
