Benefits of Playwright Automated Testing

Automation testing has become a significant part of the Software Development Life Cycle. With the increase in demand and scope, new tools for test automation are emerging in the market. If you are somewhere in the testing field you must have heard of Selenium automated testing framework and other exclusive tools ruling the market.

However, there is a new open-source tool that is now leading the market, and that is Playwright.

It’s an automated testing tool that ensures that the website/ web app is functioning correctly and the users have a positive experience. It is a solution and an addition to the Test Automation Framework.

Automated testing is not just for websites. Playwrights can test any web application or mobile app. It has the ability to integrate well with all of the most popular development workflows and tools.

In this article, we will learn about automated testing using Playwright and describe its benefits in a clear and simple manner. Before proceeding let’s first understand what a Playwright is and why it is important.

Playwright

The playwright is a JavaScript-based cross-browser automation library developed by Microsoft.  It is an open-source tool that supports programming languages like Java, Python, C#, and NodeJS.

It is created to be used with Node.js. with the aim to provide a single API to developers and testers for automating their web applications across major browser engines like Chromium, (Google Chrome, Microsoft Edge), Mozilla Firefox, and WebKit(Apple Safari). So, once tests are written can be executed across all browsers with no or minimal configuration.

It enables the testers to reduce the time and effort required to test by automatically generating test scripts. The playwright can be used to validate the accuracy of the data, simulate user interactions, and test server-side logic.

One of its most liked features is visual comparison. It captures a snapshot of a page or component, in various different viewports and in different browsers and compares the look of the component before and after the update.  This helps to ensure that the deployment has not created any unexpected visual changes on that specific component.

Why Choose Playwright as an Automation Framework

The playwright is a cloud-based performance logic and automation, testing, and continuous delivery platform. It enables teams to deliver high-quality applications faster and improve developer productivity by integrating best practices for automated testing.

The Playwright Automated Test Framework is a framework for writing, testing, and running powerful stable automated tests. It is designed to be easy to use and integrate with existing systems.

Playwright automates the testing efforts by providing end-to-end testing of the application on all targeted platforms. You can rely on Playwright to run a wide number of tests automatically for faster, more reliable, and more capable testing.

Benefits of Playwright automated testing

Despite being new in the market Playwright is extremely active in releasing new features. This framework has managed to mark its position against other mature frameworks like Selenium and Appium. The playwright helps to automate test scenarios and guarantees that the application works as it should.

It covers five techniques for testing, which include unit testing, integration testing, functional testing, performance testing, and stress testing. It’s generally considered to be developer-friendly. Below are some of the reasons why Playwright testing is preferred.

API Testing

The playwright supports API testing. It automates the process of submitting requests and verifying the response. This helps in ensuring that the API is functioning correctly and meeting the expectations of the users. Other than these it also supports Functional, and End to End Testing. And with a Third-party plugin, it can also be integrated with Accessibility Testing

Multi-Language Support

The playwright provides multiple programming language support like Java, C#, Python, and Javascript/ Typescript this feature makes it a popular choice among developers and testers.

Parallel Browser Testing

The playwright also supports parallel testing which is the execution of tests simultaneously or parallelly for multiple web pages through Browser Context. For example creating new, individual browser profiles for each test case.  when multiple web pages are tested simultaneously provides full isolation and that helps scale up testing.

User-Friendly Documentation

This feature of Playwright makes it easy to get started using the tool. The documentation includes a quick start guide, tutorials, and API references, making it more user-friendly.

Debugging Tools Support

The playwright provides a number of different debugging options making it developer-friendly. Some debugging options it includes are Playwright Inspector, VSCode Debugger, Browser Developer Tools, Built-in Reporters, Third-Party Test Runner Supports, Videos and Screenshots, Automatic Waiting, etc.

No need to Access the Code Base

The playwright is easy to use for automated testing because it does not require access to the code base to function. All of the work takes place on the UX side of things, keeping things neatly separated.

Cost and time saving

The advantages of using a playwright automated testing tool are that they allow you to save costs and time by eliminating the tedious process of manual testing, have an easy-to-install solution that works on most operating systems, and be able to test mobile applications.

Reduced human error

The benefits of using this software are that it helps you to avoid human errors and ensures consistency between the page’s design and contents. This is done through automated testing.

Integration support

The playwright is a real-time automated test and analysis tool. Playwright’s benefits include: Ready to go out of box integration with all major testing frameworks including Selenium WebDriver, QUnit, and JUnit. Customizable test reports can be created using a visual designer or by automatically generating output as needed.

Enhanced test accuracy and coverage

Playwrights can test complex applications across multiple languages, mobile web apps, and platforms. It has an in-built auto-wait function that allows repeating the significant checks on elements and requested actions till they all become actionable. This improves reliability and shortens test authoring.

Limitations of Playwright Framework

Carrying a lot of benefits, Playwright has some limitations as well. Here they are-

  • Though Playwright is new to the market, the scope for improvement is still evolving.
  • The playwright does not support Legacy Microsoft Edge or IE1.
  • The Playwright API cannot be operated in Java or Ruby.
  • The playwright doesn’t support Native Mobile Apps. It uses desktop browsers to emulate mobile devices.
  • Although its documentation is excellent, being new it does not provide good community support. Since the user base is still rising.
