Selenium WebDriver Interface

The interface WebDriver represents the main interface for testing a web browser instance. If you are using Selenium 2 then it is highly recommended to use the WebDriver instance because of the benefits suggested in my previous posts.
This interface provides most of the basic requirements for testing a web application. Normally the testing of a web application requires either one or all of the following three functions:

· Controling the browser
· Selection of WebElement
· Debugging aids
The methods in this class provide solutions to the requirements in all the three categories mentioned above:

· Control of the browser:

• get(): Loads the web page rendered by the URL string passed to this method. Similar results can be obtained by using WebDriver.Navigation.to(String)
• navigate():Loads the web page rendered by the URL and access browser history
• close(): Closes the ‘Current’ browser window
• quite(): Closes ‘All’ browser windows associated with the webDriver instance
• switchTo(): Changes current window and redirects all commands to the new ‘current’ window (example: switchTo().window(String))
• manage(): Enables access to browser menu items, such as add cookies, logs etc

· Selection of WebElement:

• findElement(): Returns the first ‘Webelement’ found
• findElements(): Returns all the ‘WebElements’ found in the current web page

· Debugging aids:

• getCurrentUrl(): Returns the current URL loaded in the browser session
• getPageSource(): Returns HTML source of the current page loaded in the browser
• getTitle(): Returns the title of current page
• getWindowHandle(): Return unique string identifier of the current window in the driver instance
• getWindowHandles(): Return identifiers of all the windows in the driver instance
