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.
