Simple and concise
WebDriver is simple, it is designed as a concise and compact programming interface.
Works in all major browsers
Through a simple setup, WebDriver can be used with all major browsers. Automate real user interactions in Firefox, Safari, Edge, Chrome, Internet Explorer and more! Selenium WebDriver refers to both the language bindings and the implementations of the individual browser controlling code. This is commonly referred to as just WebDriver.
WebDriver is a W3C Recommendation!
The W3C is an international community that works to develop Web standards. In June 2018, WebDriver became a W3C recommendation. What does this mean? Major browser vendors (Mozilla, Google, Apple, Microsoft) support WebDriver and work constantly to improve the browsers and browser controlling code, which leads to a more uniform behaviour across the different browsers, making your automation scripts more stable.
Simple, turn-key solution to quickly author reliable end-to-end tests. Works out of the box for any web app.
Enjoy easier test debugging with rich IDE features like setting breakpoints and pausing on exceptions.
Run your tests on any browser/OS combination in parallel using the Command-line Runner for Selenium IDE.
Multiple browsers, versions, and operating systems
Grid helps you to run your automation scripts across multiple combinations of browsers, versions and operating systems.
Reduce execution time
Speed up execution and cut down overall run time of your automation scripts. You still need scripts that can run in parallel though!
