E2E Command
This command invokes the e2e-runner agent to generate, maintain, and execute end-to-end tests using Playwright.
What This Command Does
Generate Test Journeys - Create Playwright tests for user flows
Run E2E Tests - Execute tests across browsers
Capture Artifacts - Screenshots, videos, traces on failures
Upload Results - HTML reports and JUnit XML
Identify Flaky Tests - Quarantine unstable tests
When to Use
Use /e2e when:
Testing critical user journeys (login, trading, payments)
Verifying multi-step flows work end-to-end
Testing UI interactions and navigation
Validating integration between frontend and backend
Preparing for production deployment
How It Works
The e2e-runner agent will:
Analyze user flow and identify test scenarios
Generate Playwright test using Page Object Model pattern
Run tests across multiple browsers (Chrome, Firefox, Safari)
Capture failures with screenshots, videos, and traces
Generate report with results and artifacts
Identify flaky tests and recommend fixes
Example Usage
User: /e2e Test the market search and view flow
Agent (e2e-runner):
# E2E Test Generation: Market Search and View Flow
## Test Scenario Identified
**User Journey:** Market Search → View Results → Click Market → View Details
**Test Coverage:**
1. Navigate to markets page
2. Perform semantic search
3. Verify search results
4. Click on first result
5. Verify market details page loads
6. Verify chart renders
## Generated Test Code
```typescript
// tests/e2e/markets/search-and-view.spec.ts
import { test, expect } from '@playwright/test'
import { MarketsPage } from '../../pages/MarketsPage'
import { MarketDetailsPage } from '../../pages/MarketDetailsPage'
test.describe('Market Search and View Flow', () => {
test('user can search markets and view details', async ({ page }) => {
// 1. Navigate to markets page
const marketsPage = new MarketsPage(page)
await marketsPage.goto()
// Verify page loaded
await expect(page).toHaveTitle(/Markets/)
await expect(page.locator('h1')).toContainText('Markets')
// 2. Perform semantic search
await marketsPage.searchMarkets('election')
// Wait for API response
await page.waitForResponse(resp =>
resp.url().includes('/api/markets/search') && resp.status() === 200
)
// 3. Verify search results
const marketCards = marketsPage.marketCards
await expect(marketCards.first()).toBeVisible()
const resultCount = await marketCards.count()
expect(resultCount).toBeGreaterThan(0)
// Take screenshot of search results
await page.screenshot({ path: 'artifacts/search-results.png' })
// 4. Click on first result
const firstMarketTitle = await marketCards.first().textContent()
await marketCards.first().click()
// 5. Verify market details page loads
await expect(page).toHaveURL(/\/markets\/[a-z0-9-]+/)
const detailsPage = new MarketDetailsPage(page)
await expect(detailsPage.marketName).toBeVisible()
await expect(detailsPage.marketDescription).toBeVisible()
// 6. Verify chart renders
await expect(detailsPage.priceChart).toBeVisible()
// Verify market name matches
const detailsTitle = await detailsPage.marketName.textContent()
expect(detailsTitle?.toLowerCase()).toContain(
firstMarketTitle?.toLowerCase().substring(0, 20) || ''
)
// Take screenshot of market details
await page.screenshot({ path: 'artifacts/market-details.png' })
})
test('search with no results shows empty state', async ({ page }) => {
const marketsPage = new MarketsPage(page)
await marketsPage.goto()
// Search for non-existent market
await marketsPage.searchMarkets('xyznonexistentmarket123456')
// Verify empty state
await expect(page.locator('[data-testid="no-results"]')).toBeVisible()
await expect(page.locator('[data-testid="no-results"]')).toContainText(
/no.*results|no.*markets/i
)
const marketCount = await marketsPage.marketCards.count()
expect(marketCount).toBe(0)
})
test('can clear search and see all markets again', async ({ page }) => {
const marketsPage = new MarketsPage(page)
await marketsPage.goto()
// Initial market count
const initialCount = await marketsPage.marketCards.count()
// Perform search
await marketsPage.searchMarkets('trump')
await page.waitForLoadState('networkidle')
// Verify filtered results
const filteredCount = await marketsPage.marketCards.count()
expect(filteredCount).toBeLessThan(initialCount)
// Clear search
await marketsPage.searchInput.clear()
await page.waitForLoadState('networkidle')
// Verify all markets shown again
const finalCount = await marketsPage.marketCards.count()
expect(finalCount).toBe(initialCount)
})
})

# Run the generated test
npx playwright test tests/e2e/markets/search-and-view.spec.ts
Running 3 tests using 3 workers
✓ [chromium] › search-and-view.spec.ts:5:3 › user can search markets and view details (4.2s)

Artifacts generated:
- artifacts/search-results.png
- artifacts/market-details.png
- playwright-report/index.html
## Test Artifacts
When tests run, the following artifacts are captured:
**On All Tests:**
- HTML Report with timeline and results
- JUnit XML for CI integration
**On Failure Only:**
- Screenshot of the failing state
- Video recording of the test
- Trace file for debugging (step-by-step replay)
- Network logs
- Console logs
## Viewing Artifacts
```bash
# View HTML report in browser
npx playwright show-report
# View specific trace file
npx playwright show-trace artifacts/trace-abc123.zip
# Screenshots are saved in artifacts/ directory
open artifacts/search-results.png
Flaky Test Detection
If a test fails intermittently:
⚠️ FLAKY TEST DETECTED: tests/e2e/markets/trade.spec.ts
Test passed 7/10 runs (70% pass rate)
Common failure:
"Timeout waiting for element '[data-testid="confirm-btn"]'"
Recommended fixes:
1. Add explicit wait: await page.waitForSelector('[data-testid="confirm-btn"]')
2. Increase timeout: { timeout: 10000 }
3. Check for race conditions in component
4. Verify element is not hidden by animation
Quarantine recommendation: Mark as test.fixme() until fixed
Browser Configuration
Tests run on multiple browsers by default:
✅ Chromium (Desktop Chrome)
✅ Firefox (Desktop)
✅ WebKit (Desktop Safari)
✅ Mobile Chrome (optional)
Configure in playwright.config.ts to adjust browsers.
E2E tests involving real money MUST run on testnet/staging only
Never run trading tests against production
Set test.skip(process.env.NODE_ENV === 'production') for financial tests
Use test wallets with small test funds only
Integration with Other Commands
Use /plan to identify critical journeys to test
Use /tdd for unit tests (faster, more granular)
Use /e2e for integration and user journey tests
Use /code-review to verify test quality
