Playwright
Microsoft's end-to-end testing framework for web apps. Supports Chromium, Firefox, and WebKit with a single API, auto-waiting, network interception, and visual comparison testing.
Why Playwright?
E2E browser testing across Chrome, Firefox, Safari
You need visual regression, network mocking, or file downloads
CI pipeline testing — Playwright's Docker image is battle-tested

Common usage patterns
Network request interception
Mock API responses in browser tests
// tests/api-mock.spec.ts
import { test, expect } from '@playwright/test';
test('shows mocked user data', async ({ page }) => {
await page.route('/api/users', (route) =>
route.fulfill({
status: 200,
contentType: 'application/json',
body: JSON.stringify([{ id: 1, name: 'Alice' }]),
})
);
await page.goto('/users');
await expect(page.getByText('Alice')).toBeVisible();
});Visual comparison test
Screenshot-based regression testing
// tests/visual.spec.ts
import { test, expect } from '@playwright/test';
test('homepage matches snapshot', async ({ page }) => {
await page.goto('/');
await page.waitForLoadState('networkidle');
await expect(page).toHaveScreenshot('homepage.png', {
maxDiffPixels: 100,
});
