Drivers are required for different types of browsers. 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.
In other words, Selenium WebDriver is a web framework that permits you to execute cross-browser tests. This tool is used for automating web-based application testing to verify that it performs expectedly. Selenium WebDriver also allows you to choose a programming language to create test scripts.
