Screenshots are desirable for bug analysis. Selenium can automatically take screenshots during execution. You need to type cast WebDriver instance to TakesScreenshot.

How to Take Screenshot in Selenium WebDriver

Taking Screenshot in Selenium is a 3 Step process

Step 1) Convert web driver object to TakeScreenshot

TakesScreenshot scrShot =((TakesScreenshot)webdriver);

Step 2) Call getScreenshotAs method to create image file

File SrcFile=scrShot.getScreenshotAs(OutputType.FILE);

Step 3) Copy file to Desired Location

Example: In this example we will take screenshot of http://demo.guru99.com/V4/ & save it as C:/Test.png

package Guru99TakeScreenshot;

import java.io.File;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.annotations.Test;

public class Guru99TakeScreenshot {

    @Test

    public void testGuru99TakeScreenShot() throws Exception{

		WebDriver driver ;
    	System.setProperty("webdriver.firefox.marionette","C:\\geckodriver.exe");
    	driver = new FirefoxDriver();

        //goto url

        driver.get("http://demo.guru99.com/V4/");

        //Call take screenshot function

        this.takeSnapShot(driver, "c://test.png") ;     

    }

    /**

     * This function will take screenshot

     * @param webdriver

     * @param fileWithPath

     * @throws Exception

     */

    public static void takeSnapShot(WebDriver webdriver,String fileWithPath) throws Exception{

        //Convert web driver object to TakeScreenshot

        TakesScreenshot scrShot =((TakesScreenshot)webdriver);

        //Call getScreenshotAs method to create image file

                File SrcFile=scrShot.getScreenshotAs(OutputType.FILE);

            //Move image file to new destination

                File DestFile=new File(fileWithPath);

                //Copy file at destination

                FileUtils.copyFile(SrcFile, DestFile);

    }

}
