Best Selenium Alternatives in 2021

Are you looking for Selenium alternatives and don’t know where to start from?

Don’t look elsewhere, you’ve come to the right place.

Selenium has critically changed the automation testing history but there are some Selenium Alternatives that are good to try.

Selenium is one of the automation testing tools which is an open-source tool. Selenium automates web application. 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.

There are some challenges and limitation in Selenium

As we all know Selenium WebDriver is a tool that automates the browser to mimic real user actions on the web. Selenium is a free open source testing tool. Some of the challenges with Selenium WebDriver are as follows:

  1. We cannot test the windows application
  2. We cannot test mobile apps
  3. Limited reporting
  4. Handling dynamic Elements
  5. Handling page load
  6. Handle pop up windows
  7. Handling captcha
