Selenium WebDriver JavaScript

The web testing standard

Selenium WebDriver has become the standard tool for automated web testing. It has received an endorsement from W3C (World Wide Web Consortium), the community which works on web standards development and Selenium 4 is W3C compliant. It is open-source and provides a powerful set of tools for testing your web site. It is available on any platform and can be used with just about any web browser, including remote execution via Selenium Grid.

You can also integrate it into a huge variety of frameworks such as Cucumber, SpecFlow, Mocha etc, as well as testing frameworks such as NUnit, xUnit, JUnit, MSTest etc., and use your choice of assertion libraries. It also integrates very easily into Continuous Integration Tools such as Jenkins, Azure DevOps, TeamCity etc.
