Why Playwright Is Becoming the Top Choice for Cross‑Browser UI Testing

Playwright is an open‑source UI automation testing tool from Microsoft, first released in February 2020 (v0.10.0) and now at version 1.18.0, with rapid iteration.

In just two years Playwright has become widely adopted; it topped the Best of JS list for new GitHub stars in 2021, indicating strong community interest.

Cross‑Browser Support

Playwright supports all modern browser engines—Chromium, WebKit, and Firefox—covering Chrome, Edge, Safari, and Opera, making it ideal for compatibility testing compared to tools like Puppeteer.

Multi‑Language APIs

Playwright provides APIs for TypeScript, JavaScript, Python, .NET, and Java, allowing developers from various backgrounds to write tests in their preferred language.

<code>const { chromium, firefox, webkit } = require('playwright');
(async () => {
  const browser = await chromium.launch(); // Or 'firefox' or 'webkit'.
  const page = await browser.newPage();
  await page.goto('http://example.com');
  // other actions...
  await browser.close();
})();</code>

Saving Login State

Playwright can store authentication state and reload it in subsequent tests, avoiding repeated logins.

Isolated Execution Contexts

The Context feature creates isolated environments within a single browser instance, preventing interference between tests, including separate cookies and storage.

<code>const { chromium } = require('playwright');
// Create a Chromium browser instance
const browser = await chromium.launch();
// Create two isolated browser contexts
const userContext = await browser.newContext();
const adminContext = await browser.newContext();
// Create pages and interact with contexts independently
</code>

Powerful Selectors

Playwright supports various selector engines such as CSS and XPath, offering a friendly API for element location.

<code>// Click a <button> that has either a "Log in" or "Sign in" text.
await page.locator('button:has-text("Log in"), button:has-text("Sign in")').click();</code>

Automatic Waiting

Before interacting with elements, Playwright performs built‑in checks and waits for elements to become actionable, eliminating the need for manual wait timers.

Testing Capabilities

Playwright includes assertions, API testing, and test annotations, positioning it as a modern alternative to Selenium with better developer experience, performance, mobile support, and script recording.

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

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  const title = page.locator('.navbar__inner .navbar__title');
  await expect(title).toHaveText('Playwright');
});</code>

Overall, Playwright is gaining momentum and is worth learning for developers interested in reliable, cross‑browser automation.
