Capturing screen shots in webdriver TestNG framework using ITestResult interface

Hello Friends,

 

We all know the importance of test evidences in our test delivery. While raising a defect also, we need fail evidences that helps developer to identify the issue and fix it.

Ok so now here we will see in detail, how can we capture the fail test screens in web driver using  TestNG framework.

First we will create an Utility class with a method "captureScreenShot" Below see the code:

package util;

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;

public class utility

{

      

public static void captureScreenShot(WebDriver driver , String screenshotName) throws IOException

 {           

 

TakesScreenshot ts = (TakesScreenshot)driver;

File sourcefile = ts.getScreenshotAs(OutputType.FILE);

FileUtils.copyFile(sourcefile, new File("./Screenshots/" + screenshotName +".png"));

      

  }

}

So we will use this method “captureScreenShot” in our test where ever required to capture screenshot.

Now let’s create a class eg. Facebook.java where we will create methods as our test cases for login validation. In addition we will create a method “teardown” where we will use “ITesttResult” interface to manage evidences. See how it done:

package testcases;

import java.io.IOException;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.Assert;

import org.testng.ITestResult;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.Test;

import util.utility;

public class facebook {

       WebDriver driver;

      

       @Test

       public void login()

       {

              driver = new FirefoxDriver();

              driver.get("https://facebook.com");

              driver.manage().window().maximize();

              driver.findElement(By.id("email")).sendKeys("Vishal");

              driver.findElement(By.id("pass")).sendKeys("Sachan");

              driver.findElement(By.id("u_0_m")).click();

              driver.manage().timeouts().implicitlyWait(1000, TimeUnit.SECONDS);

              String actual = driver.findElement(By.className("_1tp8")).getText();

              Assert.assertEqual(actual, "The password that you've entered is incorrect");

              driver.quit();

       }

      

       @AfterMethod

       public void terdown(ITestResult result) throws IOException

       {

              if(ITestResult.FAILURE== result.getStatus())

              {

               utility.captureScreenShot(driver, result.getName());

              }

       }

      

}

If you see we have used ITestResult interface to get the status of a method after run and using that status we apply a condition that is the result(status) of method is failed, we call the captureSceenShot method of utility class.

Here we are also saving the evidence name as its testcase(method name). So it is compete test. You can add N number of test cases in this and after every method run , 'teardown' will be executed and it used @AfterMethod annotation.

Please try this out and write in comments in case of any issue faced.
