Getting Started with Playwright E2E Testing

Modern web applications need more than unit tests.

You also need to test real user flows such as:

• Login
• Checkout
• Form submissions
• Navigation

This is where Playwright becomes useful.

Why Playwright?

Playwright is a modern E2E testing framework developed by Microsoft.

Main advantages:

• Cross-browser support
• Auto waiting
• Parallel test execution
• Fast and reliable
• Works with Chromium, Firefox, and WebKit
• Installation

npm init playwright@latest

Simple Login Test

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

test('user can login', async ({ page }) => {
  await page.goto('https://example.com/login');

  await page.fill('#email', '[email protected]');
  await page.fill('#password', '123456');

  await page.click('button[type="submit"]');

  await expect(page).toHaveURL('/dashboard');
});

One of the Best Features: Auto Waiting

Playwright automatically waits for elements to become available before interacting with them.

await page.click('#submit');

In many cases, you don't need manual waits anymore.

Running Tests

npx playwright test

You can also run Playwright in UI mode:

npx playwright test --ui

I personally use this mode a lot while debugging and fixing my tests.

If you are building production-grade frontend applications, adding E2E testing to your workflow is worth considering.
