Exploring Automation Testing with Playwright: A Modern Alternative to Selenium


Automation testing has long been a cornerstone of efficient software development. Among the many tools available, Selenium has been a go-to for developers due to its flexibility and extensive community support. However, in recent years, Playwright has emerged as a powerful competitor, offering several advanced features and improvements that make it a compelling choice for modern web testing. In this article, we’ll explore what makes Playwright stand out, how it compares to Selenium, and why you might consider it for your next project. We’ll also dive into a hands-on example of a Playwright test in C# to give you a taste of its capabilities.

What is Playwright?

Playwright is an open-source automation framework developed by Microsoft that enables reliable end-to-end testing for modern web applications. It supports multiple browsers like Chrome, Firefox, and Safari, and can be used with various programming languages such as JavaScript, TypeScript, Python, C#, and Java. Since its release, Playwright has gained traction for its robust feature set and ease of use, making it a favorite among developers seeking a versatile and powerful testing tool.

How Does Playwright Compare to Selenium?

1. Multi-Language Support

While Selenium also supports multiple languages, Playwright excels by providing a more consistent and integrated experience across all supported languages. Whether you’re working with JavaScript, TypeScript, Python, C#, or Java, Playwright offers a unified API that simplifies cross-language transitions and makes it easier for teams to collaborate.

2. Native Browser Contexts

Playwright’s ability to create isolated browser contexts is a game-changer. Unlike Selenium, which often requires separate sessions or complex configurations for parallel tests, Playwright can spin up multiple browser contexts within a single instance. This isolation enables efficient parallel testing, reducing resource consumption and increasing test speed.

3. Built-In Network Interception

Playwright includes built-in network interception capabilities that allow you to mock and manipulate network requests directly within your tests. This feature is invaluable for testing how your application handles different network conditions, such as slow connections or server errors, without relying on external tools or complex setups.

4. Headless Browser Mode by Default

Although Selenium supports headless browser testing, it often requires additional configuration. Playwright, on the other hand, runs headless by default, streamlining the process and making it simpler to integrate into continuous integration (CI) pipelines.

5. Cross-Browser Testing with a Single API

Playwright provides a unified API that works seamlessly across multiple browsers. Whether you’re testing on Chromium, WebKit, or Firefox, the same codebase can be used, minimizing the need for browser-specific adjustments and ensuring a more consistent testing experience.

6. Enhanced Automation Features

Playwright’s advanced automation capabilities include better support for modern web app features like single-page applications (SPAs), iframes, and complex user interactions. It also offers automatic waits, meaning it can wait for elements to be actionable before performing actions, reducing the flakiness often associated with traditional web automation tools.

Why Use Playwright?

Simplified Testing Process

With its robust API and comprehensive feature set, Playwright simplifies the automation testing process. It eliminates many of the pain points associated with setting up and maintaining tests in Selenium, allowing you to focus on writing effective tests rather than configuring your environment.

Speed and Efficiency

Playwright’s architecture and capabilities enable faster, more efficient tests. Its ability to run tests in isolated browser contexts within the same instance and support for headless mode by default means you can execute tests quickly and in parallel, significantly reducing the overall testing time.

Strong Community and Support

Despite being relatively new compared to Selenium, Playwright boasts a strong and active community. Microsoft’s backing ensures ongoing development and support, making it a reliable choice for future-proofing your automation testing strategy.

Flexibility Across Different Environments

Playwright’s cross-browser and cross-platform support make it highly versatile. Whether you need to test on Windows, macOS, or Linux, or across different browsers and devices, Playwright provides the tools necessary to ensure comprehensive coverage and compatibility.

Hands-On Example: Navigating Google.com with Playwright in C#

To give you a practical glimpse into Playwright, let’s walk through an example of a C# test script that navigates to Google.com using Chrome.


Before we start, ensure you have the following installed:

You can install Playwright for .NET via NuGet with the following command:

Writing the Test

Here’s a simple test script to navigate to Google.com and take a screenshot:


  1. Initialization: We start by creating an instance of Playwright and launching a Chromium browser. The Headless option is set to false to see the browser in action; you can change it to true for headless mode.
  2. Browser Context and Page: We create a new browser context and a page within that context.
  3. Navigation: The script navigates to https://www.google.com.
  4. Screenshot: It captures a screenshot of the page and saves it as google.png.
  5. Cleanup: Finally, the browser instance is closed.


Playwright represents a significant advancement in the world of automation testing, offering a powerful and flexible alternative to Selenium. With its multi-language support, built-in network interception, and advanced automation features, Playwright is designed to meet the needs of modern web applications. Whether you’re a seasoned automation tester or new to the field, Playwright provides the tools and capabilities to streamline your testing process and ensure robust, reliable tests.
