E2E Testing with Playwright 1.57+

Validate critical user journeys end-to-end with AI-assisted test generation.

When to Use

  • Critical user flows (checkout, signup, payment)
  • Cross-browser testing
  • Visual regression testing
  • Full stack validation
  • AI-assisted test generation and healing

Quick Reference - Semantic Locators

// ✅ PREFERRED: Role-based locators (most resilient)
await page.getByRole('button', { name: 'Add to cart' }).click();
await page.getByRole('link', { name: 'Checkout' }).click();

// ✅ GOOD: Label-based for form controls
await page.getByLabel('Email').fill('test@example.com');

// ✅ ACCEPTABLE: Test IDs for stable anchors
await page.getByTestId('checkout-button').click();

// ❌ AVOID: CSS selectors and XPath (fragile)
// await page.click('[data-testid="add-to-cart"]');

Locator Priority: getByRole() > getByLabel() > getByPlaceholder() > getByTestId()

Basic Test

import { test, expect } from '@playwright/test';

test('user can complete checkout', async ({ page }) => {
  await page.goto('/products');
  await page.getByRole('button', { name: 'Add to cart' }).click();
  await page.getByRole('link', { name: 'Checkout' }).click();
  await page.getByLabel('Email').fill('test@example.com');
  await page.getByRole('button', { name: 'Submit' }).click();
  await expect(page.getByRole('heading', { name: 'Order confirmed' })).toBeVisible();
});

AI Agents (1.57+ - NEW)

# Generate test plan
npx playwright agents planner --url http://localhost:3000/checkout

# Generate tests from plan
npx playwright agents generator --plan checkout-test-plan.md

# Auto-repair failing tests
npx playwright agents healer --test checkout.spec.ts

New Features (1.57+)

// Assert individual class names
await expect(page.locator('.card')).toContainClass('highlighted');

// Flaky test detection
export default defineConfig({
  failOnFlakyTests: true,
});

// IndexedDB storage state
await page.context().storageState({
  path: 'auth.json',
  indexedDB: true  // NEW
});

Anti-Patterns (FORBIDDEN)

// ❌ NEVER use CSS selectors for user interactions
await page.click('.submit-btn');

// ❌ NEVER use hardcoded waits
await page.waitForTimeout(2000);

// ❌ NEVER test implementation details
await page.click('[data-testid="btn-123"]');

// ✅ ALWAYS use semantic locators
await page.getByRole('button', { name: 'Submit' }).click();

// ✅ ALWAYS use Playwright's auto-wait
await expect(page.getByRole('alert')).toBeVisible();

Critical User Journeys to Test

  1. Authentication: Signup, login, password reset
  2. Core Transaction: Purchase, booking, submission
  3. Data Operations: Create, update, delete
  4. User Settings: Profile update, preferences
