Why Selenium is the most preferred tool for automation testing?

Hi Tom,

Selenium is a framework for automating web application testing across various browsers. Selenium has a few unique features that make it stand out from other similar tools:

  1. Multi-browser support: Selenium supports almost all the common browsers and operating systems such as Opera, Chrome, Firefox, Internet Explorer and many others.

  2. Cross-platform support: It provides support to run tests on different operating systems like Windows, Linux and Mac OS X.

  3. Extensibility: It is an open source tool with modular architecture and has bindings for several programming languages.

  4. WebDriver API: This allows you to write tests using one programming language (for example Java) and execute them in another (like Python). However, this feature is available only in Selenium 2.. versions.

  5. Portable: It can be run on several operating systems including Windows, Linux, Mac OS X etc.

  6. Open source: Selenium is an open source tool with MIT license so that anyone can use its source code for free for any purpose.

Though there are a lot of new tools available in the market that are capable of offering extensive benefits and features over selenium.

But, Selenium is a name that carries a legacy of automation testing. Besides, the extensive ease of use, open-source nature, and extensive community of testers make it easy to use selenium for all kinds of test automation projects.

Above all, the support of a large number of programming languages and the easy approach to using selenium on the browser makes it a highly preferred tool. More importantly, the introduction of selenium 4 with an enhanced selenium grid, upgraded selenium IDE, relative locators, and of course, improved documentation has made it even more user-friendly.
