Automation testing has revolutionized how software teams ensure product quality. In earlier days, testing was manual testers would interact with web pages, click buttons, fill forms, and verify outputs. This process was slow, repetitive, and error-prone.
As web applications grew more dynamic, automation frameworks like Selenium emerged. Selenium introduced browser control via code but often faced synchronization issues, flaky tests, and slow execution.
In 2020, Microsoft introduced Playwright, a next-generation automation framework built for the modern web. Designed around new browser APIs, Playwright makes testing faster, more reliable, and simpler particularly when combined with JavaScript, the web’s native language.
Playwright is an open-source automation library that enables developers to control browsers using JavaScript or TypeScript. It supports Chromium, Firefox, and WebKit, providing cross-browser testing through a single codebase.
In essence, Playwright replicates real user interactions clicking, typing, navigating, uploading files, and verifying content ensuring consistent behavior across browsers and devices.
Core Idea:
Playwright doesn’t test your code directly; it tests your actual web app inside a browser, mirroring real user actions for greater accuracy and confidence.
Playwright stands out by combining the strengths of Selenium, Cypress, and Puppeteer while solving their long-standing issues.
Cross-Browser Support: Chrome, Edge, Firefox, and Safari are all natively supported.
Faster, More Stable Tests: Auto-waiting eliminates flaky timing errors.
Multi-Context Execution: Run multiple user sessions simultaneously.
Network Control: Intercept, mock, or modify API requests and responses.
Modern Syntax: Uses async/await, keeping tests clean and readable.
CI/CD Friendly: Works seamlessly with Jenkins, GitHub Actions, Azure DevOps, and GitLab pipelines.
Step 1: Install Node.js (version 16 or higher).
Step 2: Initialize a new project.
Step 3: Install Playwright.
Step 4: Download browser binaries.
Step 5: Verify installation.
You’re now ready to run your first automation script.
Each Playwright test contains these components:
| Component | Purpose |
|---|---|
| test() | Defines a test case |
| page | Represents a browser tab |
| expect() | Assertion method |
| beforeEach() | Setup before each test |
| afterEach() | Cleanup after each test |
Example:
Auto-Wait: Waits for elements automatically before performing actions.
Browser Contexts: Run isolated sessions for different users.
Device Emulation: Test mobile responsiveness.
Network Interception: Mock APIs or simulate network delays.
Tracing & Reporting: Capture trace files and generate visual reports.
Example of mocking:
Playwright’s architecture enables its performance and reliability:
Playwright Client - Your test scripts
Playwright Core - Translates commands to browser actions
Browser Drivers - Communicate with browsers
Isolated Contexts - Run parallel sessions
Unlike Selenium, Playwright doesn’t rely on HTTP protocols making it faster and less error-prone.
Run tests in headed mode:
Use debug mode:
Pause execution for inspection:
The Playwright Inspector lets you replay and debug actions interactively.
Playwright runs tests across multiple browsers and sessions simultaneously:
This ensures true cross-browser coverage, reducing compatibility risks.
Playwright fits seamlessly into DevOps pipelines.
Example (GitHub Actions):
| Feature | Selenium | Cypress | Playwright |
|---|---|---|---|
| Cross-browser | ✅ | ❌ | ✅ |
| Headless Execution | ✅ | ✅ | ✅ |
| Multi-tab Handling | ❌ | ❌ | ✅ |
| Parallel Execution | ⚠️ | ✅ | ✅ |
| Mobile Emulation | ❌ | ✅ | ✅ |
