Selenium: How to use captureentirepagescreenshot with remotedriver C# - selenium

Question

In the Selenium docs I can see how to take a normal screenshot:
http://seleniumhq.org/docs/04_webdriver_advanced.html
But I would like to use captureentirepagescreenshot with a remote webdriver, C#
Is this possible? any examples?

Answer 1

Please use selenium webdriver version 2.33. Below code is a c# code so please download selenium webdriver dlls for .net from link http://docs.seleniumhq.org/download/
Selenium webdriver has inbuilt function called ITakesScreenshot to take screenshot runtime.
Please see below code
`public static void SaveScreenShot(string screenshotFirstName)
{
var folderLocation = "Screenshot folder path";
var screenshot = ((ITakesScreenshot)Driver).GetScreenshot();
var filename = new StringBuilder(folderLocation);
filename.Append(screenshotFirstName);
filename.Append(DateTime.Now.ToString("dd-MM-yyyy HH_mm_ss"));\\append date and time
filename.Append(".png"); \\append image extension
screenshot.SaveAsFile(filename.ToString(), System.Drawing.Imaging.ImageFormat.Png);
}`
Hope this will work for you.
Thanks,

If you use a IWebDriver implementation (such as InternetExplorerDriver, FirefoxDriver) you can simply cast it to a ITakesScreenshot interface and use the GetScreenShot() method:
IWebDriver driver = new InternetExplorerDriver();
Screenshot screenShot = ((ITakesScreenshot)driver).GetScreenshot();
screenShot.SaveAsFile(/*fullFileNameAndPath*/, ImageFormat.Png);
But if you want to to do this with a RemoteWebDriver you can't, because it doesn't implement the ITakesScreenshot interface. So, you have to create a new class based on RemoteWebDriver that implements this interface and adds the GetScreenshot() method such as:
public class ScreenShotRemoteWebDriver : RemoteWebDriver, ITakesScreenshot
{
public ScreenShotRemoteWebDriver(Uri RemoteAdress, ICapabilities capabilities)
: base(RemoteAdress, capabilities) { }
/// <summary>
/// Gets a <see cref="Screenshot"/> object representing the image of the page on the screen.
/// </summary>
/// <returns>A <see cref="Screenshot"/> object containing the image.</returns>
public Screenshot GetScreenshot()
{
// Get the screenshot as base64.
Response screenshotResponse = this.Execute(DriverCommand.Screenshot, null);
string base64 = screenshotResponse.Value.ToString();
// ... and convert it.
return new Screenshot(base64);
}
}
Now you can use it as you would for a IWebDriver:
RemoteWebDriver driver = new ScreenShotRemoteWebDriver(/*uri*/, /*capabilities*/);
Screenshot screenShot = ((ITakesScreenshot)driver).GetScreenshot();
screenShot.SaveAsFile(/*fullFileNameAndPath*/, ImageFormat.Png);
It took me sometime to understand the maze of classes and interfaces for the drivers as well, but after a while it all makes sense.
