/e2e

description: Generate and run end-to-end tests with Playwright. Creates test journeys, runs tests, captures screenshots/videos/traces, and uploads artifacts.

E2E Command

This command invokes the **e2e-runner** agent to generate, maintain, and execute end-to-end tests using Playwright.

What This Command Does

1. **Generate Test Journeys** - Create Playwright tests for user flows 2. **Run E2E Tests** - Execute tests across browsers 3. **Capture Artifacts** - Screenshots, videos, traces on failures 4. **Upload Results** - HTML reports and JUnit XML 5. **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:

1. **Analyze user flow** and identify test scenarios 2. **Generate Playwright test** using Page Object Model pattern 3. **Run tests** across multiple browsers (Chrome, Firefox, Safari) 4. **Capture failures** with screenshots, videos, and traces 5. **Generate report** with results and artifacts 6. **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)
  })
})
