Playwright Setup

Playwright allows you to test your entire application in real browsers.

Installation

bash
npm init playwright@latest

This creates:

• playwright.config.ts
• tests/ directory
• Example tests

Configuration for Next.js

typescript
// playwright.config.ts
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  testDir: './e2e',
  webServer: {
    command: 'npm run dev',
    url: 'http://localhost:3000',
    reuseExistingServer: !process.env.CI,
  },
  use: {
    baseURL: 'http://localhost:3000',
  },
  projects: [
    { name: 'chromium', use: { ...devices['Desktop Chrome'] } },
    { name: 'firefox', use: { ...devices['Desktop Firefox'] } },
    { name: 'webkit', use: { ...devices['Desktop Safari'] } },
  ],
});

The webServer option automatically starts your Next.js dev server before tests.
