Playwright

Modern End‑to‑End Testing for Web Applications

Playwright has quickly become one of the most popular automation frameworks in the world of automation. It’s fast, reliable, developer‑friendly, and built for the modern web. If you’re coming from Selenium or starting fresh, Playwright gives you a powerful and enjoyable automation experience.

What Is Playwright?

Playwright is an open-source automation framework created by Microsoft. It allows you to automate browsers like:
Chromium (Chrome, Edge)
Firefox
WebKit (Safari)
Unlike older tools, Playwright was designed for modern web apps that use dynamic content, single-page architecture, and heavy JavaScript.

Why Playwright Is So Popular

1. Auto‑wait Mechanism
Playwright automatically waits for elements to be ready — no need for manual waits or sleeps.
2. Cross‑Browser & Cross‑Platform
Run tests on:
Windows
macOS
Linux
Mobile emulation
3. Fast Execution
Playwright runs tests in parallel by default, making it extremely fast.
4. Built‑in Test Runner
It includes:
Assertions
Reporters
Parallel execution
Fixtures
5. Supports Multiple Languages
You can write Playwright tests in:
JavaScript / TypeScript
Python
Java
.NET

Installing Playwright (JavaScript Example)

Code Highlighting 

     npm init playwright@latest
This installs:
Playwright
Browsers
Example tests
Test runner

Understanding Playwright’s Core Concepts

1. Browser
Represents the actual browser instance (Chrome, Firefox, etc.)
2. Context
A clean browser profile — like an incognito window.
3. Page
A single tab inside the browser.
4. Locator
A smart way to find elements on the page.

✅ Basic Playwright Test Structure

const { test, expect } = require(‘@playwright/test’); test(‘sample test’, async ({ page }) => { await page.goto(‘https://example.com’); await expect(page).toHaveTitle(/Example/); });


🚀 Your First Playwright Script: Automating Google Search
Below is a simple, beginner‑friendly script that:
Opens Google
Types a search query
Presses Enter
Waits for results
Prints the first result title
This example uses JavaScript with the Playwright Test Runner.

✅ Playwright Script: Google Search Automation

const { test, expect } = require(‘@playwright/test’);

test(‘Google Search Automation’, async ({ page }) => {
    // Step 1: Navigate to Google
    await page.goto(‘https://www.google.com’);

    // Step 2: Accept cookies if the popup appears (optional)
    const acceptButton = page.locator(‘button:has-text(“Accept”)’);
    if (await acceptButton.count()) {
        await acceptButton.click();
    }

    // Step 3: Type search query
    await page.locator(‘input[name=”q”]’).fill(‘Playwright automation’);

    // Step 4: Press Enter
    await page.keyboard.press(‘Enter’);

    // Step 5: Wait for results
    await page.waitForSelector(‘h3’);

    // Step 6: Extract first result title
    const firstResult = await page.locator(‘h3’).first().innerText();
    console.log(‘First Result:’, firstResult);

    // Assertion (optional)
    await expect(page).toHaveTitle(/Playwright/);
});


✅ What This Script Demonstrates
page.goto()
fill()
keyboard.press()
waitForSelector()
locator().innerText()



🎯 Tips for Beginners
✅ Use Playwright Inspector
Run tests with:

npx playwright test –debug

This opens a GUI where you can:
Step through tests
Record selectors
Debug failures
✅ Prefer Locators Over XPath
Playwright’s locators are smarter and more stable.
✅ Use Auto‑Wait
Avoid manual waits — Playwright handles it for you.

🎉 Final Thoughts
Playwright is one of the most powerful tools for modern web automation. Its speed, reliability, and developer‑friendly design make it ideal for beginners and experts alike. Once you master the basics — browser, context, page, and locators — you can automate almost anything.
If you want, I can also help you with:
✅ Playwright framework design
✅ Parallel execution setup
✅ API testing with Playwright
✅ Page Object Model (POM)
✅ Playwright + Docker
✅ Playwright + CI/CD
