Top 20 Reasons To Choose Playwright For Automation Testing
Software development teams can now provide high-quality software applications with fewer errors thanks to automated testing. A relatively new automated testing framework called Playwright has received much attention lately. The top 20 reasons Playwright is a fantastic solution for automated testing will be covered in this post.
-
Testing Across Browsers
The Playwright Node.js module allows developers to create automated testing for web applications across several browsers. Testing across browsers is meant to be quick and easy. Macbeth allows developers to design tests compatible with Chrome, Firefox, Edge, Safari, and other well-known browsers. This helps ensure an application works as intended regardless of the user’s browser. Moreover, Playwright offers parallel testing, allowing developers to run tests simultaneously across various browsers, considerably reducing testing time.
-
Headless and GUI testing
Playwright, a Node.js library for automated browser testing, offers GUI and headless testing. Thanks to headless testing, users can run automated tests on a browser without launching the browser’s graphical user interface. This is advantageous as it is quicker and more dependable than manually opening and closing the browser window.
Conversely, GUI testing enables users to open a browser window and interact with the page exactly as a genuine user would. This is useful for evaluating how well a website or program interacts with its users. Headless and GUI testing are helpful to ensure that a website or application functions as intended across all browsers and contexts.
-
More Rapid Test Execution
As compared to other automated testing frameworks, Playwright offers quicker test execution. This is because utilizing only one debugging protocol reduces overhead and expedites test execution.
-
Easy Setup
The Playwright is simple to set up and takes little configuration. It is simple to set up and use immediately, thanks to a single terminal command. The Playwright API provides a straightforward mechanism for creating automated testing with little to no coding skills and is extensively documented. Because of this, utilization is incredibly easy to pick up regardless of past experience.
-
Going to test Across Platforms
Playwright enables developers to construct tests for web applications that operate on Windows, macOS, and Linux. This can save time and effort because developers can create tests once and run them across all supported platforms. Additionally, Playwright gives developers access to tools like Element Playback, which captures user input and plays it back to test the application’s response, and Visual Testing, which enables developers to compare screenshots of their application on various platforms to make sure it functions and appears as intended. These capabilities make it simpler for developers to check that their programs function properly across platforms and assist them in finding faults before users do.
-
Parallel Testing
A key advantage of Playwright is concurrent testing, which enables several tests to run simultaneously and dramatically reduces the time needed to finish a full suite of tests. Running tests simultaneously can greatly reduce the overall testing time, which is especially important for large projects with complicated test suites. Developers can also benefit from running tests in different browsers concurrently because of Playwright’s capability to generate and execute tests in multiple browsers.
Cloud based digital experience testing platforms like LambdaTest provide powerful parallel testing capabilities for Playwright testing that allow users to run multiple tests simultaneously on 50+ different browsers, operating systems, and devices. Parallel testing helps to speed up the testing process and reduce the time and effort required to test web applications on different environments.
-
Easy bug solution
Playwright’s ability to immediately spot abnormal behavior and locate the problem’s root cause makes it useful for finding and fixing faults quickly. Additionally, it can identify any bugs that alterations to the codebase might have brought on. In addition, Playwright assists in locating and fixing any unanticipated mistakes that could happen while conducting testing. Ensuring the codebase is stable, and bug-free can help to shorten the time needed to troubleshoot and resolve any issues.
-
Concurrent Queuing
One of the most important advantages of playwright automation is Integrated Waiting. It enables automated waiting for specific components to arrive on the page. This implies that the automation tool can delay executing any action until a specific element appears on the page. Ensuring that the script only executes actions when the necessary elements are present on the page helps to increase the reliability of automation scripts.
-
Powerful selectors
The time required to maintain and update tests can be decreased using strong selectors. The selectors will remain strong and dependable as tests are updated, making it simpler to rapidly recognize and update tests impacted by website changes.
-
Adaptable Timeouts
Testers may create custom timeouts for page navigation, waiting for items, and other activities in Playwright. They have more control over the testing process as a result, and successful testing is ensured.
-
Automatic Retry
Playwright automation can enable tests to be run repeatedly and automatically. There is no need for manual intervention because the automation framework will automatically retry a failed test. By doing this, the time and effort needed to start a complete test suite are reduced. Additionally, ensuring that the same tests are conducted numerous times before being judged successful helps to verify test accuracy and reliability. Any problems that could have gone unnoticed during the initial run can be found and fixed using this method.
-
The Use Of Well-Known Testing Frameworks
With Playwright, programmers may create tests using well-liked frameworks like Jest, Mocha, and Jasmine, as well as web driver-friendly languages like JavaScript and TypeScript. As a result, Playwright is simple to incorporate into already-existing test suites. Also, it enables developers to use the well-known syntax of the selected framework, which facilitates code comprehension. Therefore, developers can write tests more quickly and with fewer errors.
-
Page Elements
Testing professionals may write reusable code for interacting with web pages using Playwright’s support for page objects. Because of this, writing and maintaining automation scripts is made simpler, requiring less testing work. Developers may design scalable and maintainable automation tests using Playwright’s tools and capabilities, which fully support the Page Objects paradigm. It is a potent tool for implementing Page Objects in automated testing because it supports element selectors, Page classes, auxiliary classes and methods, interaction with testing frameworks, and cross-browser support.
-
Simple Snapshot Taking
One of the major benefits of using Playwright automation is the ability to take quick, easy screenshots of web pages. This feature is incredibly useful when it comes to debugging issues, testing visual changes, and more. With Playwright, you can take snapshots of the website at any point in time and compare them against the previous version. This helps you identify any changes that need to be made and gives you a better understanding of the web page layout.
-
Assistance With Mobile Devices
Playwright for testing supports Android and iOS mobile devices. It is a flexible solution for the developers who need testing of their apps across several devices.
-
Simulating simple networking parameters
Developers can now evaluate how effectively their apps function in various situations, such as limited bandwidth, excessive latency, etc. To test for device compatibility with other sorts of devices, like desktop or mobile Computers, Playwright automation can also be used to simulate various network setups.
