Benefits of using Selenium for test automation

Before you decide on an test automation solution for your web application testing, it would be wise to look at the benefits that selenium provides which I’ll be discussing in this post.

  • Selenium is an open source software. There is no licensing cost and anyone can download and use it for personal learning or business purpose. This could be a great time and cost savings, resulting in a better ROI for the team using it.

  • Selenium is portable software testing framework for web applications. The Selenium library and the tests written in Selenium can be run on Windows, Linux and Mac-OS platforms.

  • Selenium supports multiple languages like Java, C#, Ruby, Python, Javascript(node) for creation of tests. There are few other languages like Perl, PHP, R, Dart, and a few more that exist by selenium and maintained by third parties.

  • Selenium makes automated browser compatibility testing easier by supporting test runs against most modern web browsers including Firefox, Chrome, HTMLUnit (headless browser), Microsoft Edge, Opera and Safari. Although Selenium mainly focuses on desktop browser testing, Mobile browser testing can be emulated by passing specific user agent . Testing on Mobile devices (mobile app and browsers) is also supported through Appium library which is a test framework written on top of Selenium.

  • Selenium supports multiple parallel test runs on multiple machines on remote browsers using Selenium Grid. These browsers can run in different platforms or operating systems.

  • Selenium integrates well with other test tools such as TestNG (to run test suites and reporting), and Jenkins (for continuous integration). It does not restrict a test engineer’s choice for reporting tools, build systems or any other aspect of their testing framework.

  • Selenium is lightweight, and less CPU/memory intensive as compared to the other testing tools (for example UFT, RFT, SilkTest).

  • There are many ways one can add functionality to both test framework as well as test scripts in order to customize the automation for an AUT (application under test). This is perhaps Selenium’s greatest strength when compared with other automation tools.

  • Selenium WebDriver is designed to accurately simulate the way a user will interact with a web application. It supports web applications that incorporate heavy use of JavaScript and AJAX technologies to update DOM on page interactions.
