Road to capture screen shot of failed Webdriver test script part2

In my previous post ( "Road to capture screen shot of failed webdriver test script part1") I have posted how to capture screen shot using exception handling, but in this post I will show you how to capture screen shot by overriding testng listeners.

Here is code (MyListner.java) where I override onTestFailure,  onTestSuccess and onTestSkipped methods of class TestListenerAdapter.  Created function CaptureScreenShot and called it into onTestFailure function.

package com.webdriver.test;

import java.io.File;

import java.io.IOException;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

import org.testng.ITestResult;

import org.testng.TestListenerAdapter;

public class MyListner extends TestListenerAdapter{   

           

     @Override

     public void onTestFailure(ITestResult result){ 

            CaptureScreenShot(result);

            System.out.println(result.getName()+" Test Failed \n");

     }

           

     @Override

     public void onTestSuccess(ITestResult result){

           System.out.println(result.getName()+" Test Passed \n");

     }

           

     @Override

     public void onTestSkipped(ITestResult result){

           System.out.println(result.getName()+" Test Skipped \n");

     }

            

     public void CaptureScreenShot(ITestResult result){

           Object obj  = result.getInstance();

           WebDriver driver = ((FailedTestScreenCapture) obj).getDriver();

                        

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

                                         

           try {

                  FileUtils.copyFile(scrFile, new File(“screenshot/” result.getName()+".png"));

           }

           catch (IOException e) {

                e.printStackTrace();

           }

      } 

}

I called above created listeners java file in below “FailedTestScreenCapture.java” TestNg file.
