## Available Commands
When installed as a Claude Code plugin, these are available as `/pw:` commands:
| Command | What it does |
|---|---|
| `/pw:init` | Set up Playwright — detects framework, generates config, CI, first test |
| `/pw:generate <spec>` | Generate tests from user story, URL, or component |
| `/pw:review` | Review tests for anti-patterns and coverage gaps |
| `/pw:fix <test>` | Diagnose and fix failing or flaky tests |
| `/pw:migrate` | Migrate from Cypress or Selenium to Playwright |
| `/pw:coverage` | Analyze what's tested vs. what's missing |
| `/pw:testrail` | Sync with TestRail — read cases, push results |
| `/pw:browserstack` | Run on BrowserStack, pull cross-browser reports |
| `/pw:report` | Generate test report in your preferred format |
## Quick Start Workflow
The recommended sequence for most projects:
```
1. /pw:init → scaffolds config, CI pipeline, and a first smoke test
2. /pw:generate → generates tests from your spec or URL
3. /pw:review → validates quality and flags anti-patterns ← always run after generate
4. /pw:fix <test> → diagnoses and repairs any failing/flaky tests ← run when CI turns red
```
**Validation checkpoints:**
- After `/pw:generate` — always run `/pw:review` before committing; it catches locator anti-patterns and missing assertions automatically.
- After `/pw:fix` — re-run the full suite locally (`npx playwright test`) to confirm the fix doesn't introduce regressions.
- After `/pw:migrate` — run `/pw:coverage` to confirm parity with the old suite before decommissioning Cypress/Selenium tests.
### Example: Generate → Review → Fix
```bash
# 1. Generate tests from a user story
/pw:generate "As a user I can log in with email and password"
# Generated: tests/auth/login.spec.ts
# → Playwright Pro creates the file using the auth template.
# 2. Review the generated tests
/pw:review tests/auth/login.spec.ts
# → Flags: one test used page.locator('input[type=password]') — suggests getByLabel('Password')
# → Fix applied automatically.
# 3. Run locally to confirm
npx playwright test tests/auth/login.spec.ts --headed
# 4. If a test is flaky in CI, diagnose it
/pw:fix tests/auth/login.spec.ts
# → Identifies missing web-first assertion; replaces waitForTimeout(2000) with expect(locator).toBeVisible()
```
## Golden Rules
1. `getByRole()` over CSS/XPath — resilient to markup changes
2. Never `page.waitForTimeout()` — use web-first assertions
3. `expect(locator)` auto-retries; `expect(await locator.textContent())` does not
4. Isolate every test — no shared state between tests
5. `baseURL` in config — zero hardcoded URLs
6. Retries: `2` in CI, `0` locally
7. Traces: `'on-first-retry'` — rich debugging without slowdown
8. Fixtures over globals — `test.extend()` for shared state
9. One behavior per test — multiple related assertions are fine
10. Mock external services only — never mock your own app
## Locator Priority
```
1. getByRole() — buttons, links, headings, form elements
2. getByLabel() — form fields with labels
3. getByText() — non-interactive text
4. getByPlaceholder() — inputs with placeholder
5. getByTestId() — when no semantic option exists
6. page.locator() — CSS/XPath as last resort
```
