Top 10 Best Selenium Alternatives You Should Try

Best Selenium Alternatives you should try:

Selenium is a convenient and portable software testing tool specifically used for testing web applications. It acts as an API (Application Program Interface) for browser automation. Selenium is the widely used free and open-source tool used for automation testing of web applications through various browsers and platforms.

Selenium is used for functional and regression testing of web applications. Selenium supports multiple programming and scripting languages like Java, Ruby, Perl, PHP and Python to code the logic behind the test scripts.

Features of Selenium:

Below mentioned are the features of Selenium tool:

  • There is no licensing cost for Selenium users, as it is an open-source testing tool.
  • Selenium is a cross-platform tool that supports cross-browser testing.
  • Selenium users can perform tests on any operating system like Android, Windows, Mac, iOS, and Linux.
  • Selenium can be used across various browsers like Safari, Chrome, IE, Mozilla, and Opera.
  • To generate the reports and manage the test cases Selenium can be integrated with other frameworks like JUnit, TestNG and NUnit.

Drawbacks of Selenium:

There are few disadvantages of the Selenium automation testing tool.

They are:

  • Using Selenium one can test only the web applications. It is not suitable to test desktop or mobile or any standalone applications.
  • There is no consistent nominal and technical support from any team as it is an open-source tool.
  • Tests of Selenium are unstable. If new versions of Selenium libraries are released to fix an issue then it may disturb or makes the earlier test unstable.
  • Due to its low-level API, the Test maintenance in Selenium is a struggle. It doesn’t help or assist the developer to deal with the error capturing, page screenshots and element locators.
  • Even though Selenium supports its users to run parallel tests on multiple machines, that set up needs quite a bit additional knowledge without which it takes too long time to run the tests.
  • Using Selenium one cannot execute testing on images.
