Introduction to Playwright

Playwright is a modern end-to-end testing framework that enables reliable automation across all major browsers.

What is Playwright?

Playwright is an open-source Node.js library for automating web browsers. It supports Chromium, Firefox, and WebKit with a single API, making it ideal for testing modern web applications.

Key Features

• Cross-browser support (Chromium, Firefox, WebKit)
• Auto-wait for elements to be ready
• Powerful network interception capabilities
• Native mobile emulation
• Built-in test runner with parallel execution

Why Choose Playwright?

Playwright offers several advantages over traditional testing frameworks:

• Reliable automation: Eliminates flaky tests with auto-waiting and web-first assertions
• Fast execution: Runs tests in parallel across multiple browsers
• Modern API: Clean, consistent API with async/await support
• Great developer experience: Built-in debugging tools and trace viewer

Basic Example

Here's a simple Playwright test that navigates to a page and verifies the title:

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

test('has title', async ({ page }) => {
  // Navigate to the page
  await page.goto('https://playwright.dev/');

  // Expect the title to contain 'Playwright'
  await expect(page).toHaveTitle(/Playwright/);
});

test('get started link', async ({ page }) => {
  await page.goto('https://playwright.dev/');

  // Click the get started link
  await page.getByRole('link', { name: 'Get started' }).click();

  // Verify the URL
  await expect(page).toHaveURL(/.*intro/);
});
