WebDriver has provided us one  interface TakesScreenshot  for capturing the screenshot of web application and This interface provides one method names as getScreenshotAs() to capture screenshot in instance of driver.

           This getScreenshotAs() method takes argument of type 

           OutputType.File 

           or OutputType.BASE64

           or Output.BYTES. 

File scrnshot= ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

OR  ((TakesScreenshot)driver).getScreenshotAs(OutputType.BASE64);

OR  ((TakesScreenshot)driver).getScreenshotAs(OutputType.BYTES);

NOTE: Here in brackets((TakesScreenshot) is not mandatory it is just showing this driver implemented this getScreenshotAs method from “TakesScreenshot” interface

We have taken the screenshot with the help of getScreenshotsAs() method and  and now its time to copy this file somewhere in our file system or in our desktop.

 For this purpose we further use copyFile() method of the FileUtils class from theorg.apache.commons.io.FileUtils class.

Placing file in file system by using this line

FileUtils.copyFile(scrFile, new File(“e:\\main_page.png”));
