Capture Screen Shot on Failure Test cases using TestNG.

Hi guys in this post we are going to see, how to capture ScreenShot on Failure Test cases using TestNG.

Taking Screenshot on the failure is very important to understand the Bug clearly to the manual Testers and developers.

Scenarios for Testcase Failures:

1. Unable to find elements in the Webpages
2. Timeout to finding Webelements.
3. Assertion Failure
4. Application Error 

In this post we are going to see how this going to work in action.

In this Example we are going to forcefully fail the testcase  by Asserting the title.(Giving the wrong Title)

Steps:

1. We are creating a new class to capture ScreenShots alone.

import java.io.File;

import java.io.IOException;

import javax.print.attribute.standard.MediaSize.Other;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

public class CaptureScreenshot {

      

       public static void takescreenshot(WebDriver driver,String Screenshotname) throws IOException

       {

              TakesScreenshot takescreenshot=(TakesScreenshot)driver;

              File source=takescreenshot.getScreenshotAs(OutputType.FILE);

              FileUtils.copyFile(source, new File("./Screenshots/"+Screenshotname+".png"));

              System.out.println("Screenshot Taken Successfully!!!!");

             

       }

}

This class will just capture the screenshots by calling this Method in Test class

CaptureScreenshot.takescreenshot(driver, "Titlefailed");

      2. Create a new Class for the Test.

      3. On BeforeTest annotation Write code to  Open Browser and Navigate to http:\\automationplace.blogspot.com

@BeforeTest

       public void Setup()

       {

              driver=new FirefoxDriver();

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

              driver.get("http:\\automationplace.blogspot.com");

             

              //Make testcase fail by checking the Title

             

       }

       4. On the @Test annotation, Just verify the title (Here am forcefully failing the Testcase by giving wrong title on Expected String in Assert.equal method)

String ExpectedTitle="Automation";

 forcefully failing the Testcase by giving wrong title on the ExpectedTitle.

@Test

       public void verifytitle()

       {

              String ActualTitle=driver.getTitle();

              System.out.println(ActualTitle);

              //Removed "Place" string from Title to fail testcase

              Assert.assertEquals(ActualTitle, ExpectedTitle);

       }

     5. Capture ScreenShot on the @AfterMethod,

     Note :

1. We will use ITestResult Interface which will provide us the test case execution status and test case name.

2.@AfterMethod is another annotation of TestNG which will execute after evert test execution whether test case pass or fail @AfterMethod will always execute.

@AfterMethod

       public void TearDown(ITestResult result) throws IOException

       {

              //If the Testcase fail then only it enters to if condition block

             

              //.getStatus will return Test "Pass" or "Fail"

             

              System.out.println("Testcase status is"+result.getStatus());

              System.out.println("Iresult status is"+result.FAILURE);

             

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

              {

                     //Now we need to capture Screenshot

                     //use CaptureScreenshot Class to Take Screenshot

                    

                     CaptureScreenshot.takescreenshot(driver, "Titlefailed");

                    

              }

             

             

              driver.quit();

       }

1.If the Testcase fail then only it enters to if condition block

2.getStatus will return Test "Pass" or "Fail"

It will Store ScreenShot on the Project folder like this

Source Code: 

Class to take ScreenShot:  CreateScreenShot.java

import java.io.File;

import java.io.IOException;

import javax.print.attribute.standard.MediaSize.Other;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

public class CaptureScreenshot {

      

       public static void takescreenshot(WebDriver driver,String Screenshotname) throws IOException

       {

              TakesScreenshot takescreenshot=(TakesScreenshot)driver;

              File source=takescreenshot.getScreenshotAs(OutputType.FILE);

              FileUtils.copyFile(source, new File("./Screenshots/"+Screenshotname+".png"));

              System.out.println("Screenshot Taken Successfully!!!!");

             

       }

}

Class for the Testcase :FailedTestCase.java

import java.io.IOException;

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.BeforeTest;

import org.testng.annotations.Test;

public class FailedTestcase {

      

       WebDriver driver;

       String ExpectedTitle="Automation";

      

       @BeforeTest

       public void Setup()

       {

              driver=new FirefoxDriver();

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

              driver.get("http:\\automationplace.blogspot.com");

             

              //Make testcase fail by checking the Title

             

       }

      

       //Failed Testcase

       @Test

       public void verifytitle()

       {

              String ActualTitle=driver.getTitle();

              System.out.println(ActualTitle);

              //Removed "Place" string from Title to fail testcase

              Assert.assertEquals(ActualTitle, ExpectedTitle);

       }

      

      

       @AfterMethod

       public void TearDown(ITestResult result) throws IOException

       {

              //If the Testcase fail then only it enters to if condition block

             

              //.getStatus will return Test "Pass" or "Fail"

             

              System.out.println("Testcase status is"+result.getStatus());

              System.out.println("Iresult status is"+result.FAILURE);

             

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

              {

                     //Now we need to capture Screenshot

                     //use CaptureScreenshot Class to Take Screenshot

                    

                     CaptureScreenshot.takescreenshot(driver, "Titlefailed");

                    

              }

             

             

              driver.quit();

       }

      

}

Run the program .

You find the Screenshot on the project folder after Execution.

Thats it..Have a great day.

Thankyou!!!!
