WEBDRIVER & OPERATIONAL OVERVIEW OF SELENIUM WBDRIVER

WebDriver:

 WebDriver is an interface developed by selenium people which is been implemented by so many classes like FirefoxDriver, InternetExplorerDriver, ChromeDriver, AndroidDriver, IPhoneDriver, SafariDriver etc.

At present people are using selenium webdriver for functional automation because it is so simple and more powerful than older selenium RC.

For e.g.: In selenium RC we need to start and stop the selenium server through program but no need to do it in selenium webdriver.

Operational overview of selenium: while giving the instructions to selenium we need to provide the information (properties of objects) to identify the object and also what operation to be performed on that object.

           During execution selenium will work in the following way

It will first identify the object using the information which is provided by us in the program.

It will perform the action that is described in the instruction.

Object identification: In selenium we can make it identify the object in the web application with the help of properties like id, name, linkname, class, xpath, tagname etc.
