Introduction to Selenium WebDriver
The Web Driver is one of the most powerful and popular tools in the Selenium toolkit. The WebDriver comes as an extended version of the RC Selenium with superfluous advantages and addresses many of its limitations. WebDriver extends its support to many newer browsers and platforms, unlike the Selenium IDE. WebDriver also does not require that the Selenium server be started before running the test scripts, unlike Selenium RC. The Selenium RC in aggregation with the WebDriver API is known as Selenium 2.0. Selenium has been developed to support dynamic web pages and Ajax calls. It also supports several drivers for the web-based mobile test.
Selenium WebDriver Architecture
Selenium WebDriver is a browser automation structure that accepts commands and sends them to a browser. It is implemented through a specific browser driver. Control the browser by communicating directly with it. The Selenium WebDriver supports Java, C #, PHP, Python, Perl and Ruby.
There are four components of the selenium webdriver architecture:
1.Lanugage Binding or Selenium Client Library
It is nothing more than Jar files, where the language in which we write our selenium box. This means that the language we use to write the script can be Java, C #, Ruby, Python, Perl.
API Stands for Application Programming Interface. The API works as an interface between the software program and facilitates their interaction. API is software for software interaction, which means that the API works between the software and the software. With the help of API applications they talk to each other without any knowledge of the user.
It is a kind of implementation of the WebDriver interface that a developer of test scripts can use to run their test script through the WebDriver server on the remote computer.

Selenium WebDriver- Features
- Support for several browsers: Selenium WebDriver supports a wide range of browsers such as Firefox, Chrome, Internet Explorer, Opera and many more. It also supports some of the unconventional or rare browsers, such as HTMLUnit.
- Speed: WebDriver has a faster performance compared to other Selenium Suite tools. Unlike the RC, it does not require any intermediary server to communicate with the browser; instead, the tool communicates directly with the browser.
