Generate production-ready Playwright tests from a user story, URL, component name, or feature description.
Input
$ARGUMENTS"user can log in with email and password""the checkout flow""src/components/UserProfile.tsx""the search page with filters"
Steps
1. Understand the Target
Parse to determine:
$ARGUMENTS- User story: Extract the behavior to verify
- Component path: Read the component source code
- Page/URL: Identify the route and its elements
- Feature name: Map to relevant app areas
2. Explore the Codebase
Use the subagent to gather context:
Explore- Read for
playwright.config.ts,testDir,baseURLprojects - Check existing tests in for patterns, fixtures, and conventions
testDir - If a component path is given, read the component to understand its props, states, and interactions
- Check for existing page objects in
pages/ - Check for existing fixtures in
fixtures/ - Check for auth setup (or
auth.setup.tsconfig)storageState
3. Select Templates
Check in this plugin for matching patterns:
templates/| If testing... | Load template from |
|---|---|
| Login/auth flow | |
| CRUD operations | |
| Checkout/payment | |
| Search/filter UI | |
| Form submission | |
| Dashboard/data | |
| Settings page | |
| Onboarding flow | |
| API endpoints | |
| Accessibility | |
Adapt the template to the specific app — replace with actual selectors, URLs, and data.
{{placeholders}}4. Generate the Test
Follow these rules:
Structure:
typescript
import { test, expect } from '@playwright/test';
// Import custom fixtures if the project uses them
test.describe('Feature Name', () => {
// Group related behaviors
test('should <expected behavior>', async ({ page }) => {
// Arrange: navigate, set up state
// Act: perform user action
// Assert: verify outcome
});
});Locator priority (use the first that works):
- — buttons, links, headings, form elements
getByRole() - — form fields with labels
getByLabel() - — non-interactive text content
getByText() - — inputs with placeholder text
getByPlaceholder() - — when semantic options aren't available
getByTestId()
Assertions — always web-first:
typescript
// GOOD — auto-retries
await expect(page.getByRole('heading')).toBeVisible();
await expect(page.getByRole('alert')).toHaveText('Success');
// BAD — no retry
const text = await page.textContent('.msg');
expect(text).toBe('Success');Never use:
page.waitForTimeout()- or
page.$(selector)page.$$(selector) - Bare CSS selectors unless absolutely necessary
- for things locators can do
page.evaluate()
Always include:
- Descriptive test names that explain the behavior
- Error/edge case tests alongside happy path
- Proper on every Playwright call
await - -relative navigation (
baseURLnotpage.goto('/'))page.goto('http://...')
5. Match Project Conventions
- If project uses TypeScript → generate
.spec.ts - If project uses JavaScript → generate with
.spec.jsimportsrequire() - If project has page objects → use them instead of inline locators
- If project has custom fixtures → import and use them
- If project has a test data directory → create test data files there
6. Generate Supporting Files (If Needed)
- Page object: If the test touches 5+ unique locators on one page, create a page object
- Fixture: If the test needs shared setup (auth, data), create or extend a fixture
- Test data: If the test uses structured data, create a JSON file in
test-data/
7. Verify
Run the generated test:
bash
npx playwright test <generated-file> --reporter=listIf it fails:
- Read the error
- Fix the test (not the app)
- Run again
- If it's an app issue, report it to the user
Output
- Generated test file(s) with path
- Any supporting files created (page objects, fixtures, data)
- Test run result
- Coverage note: what behaviors are now tested
