How to explain the Data driven framework to the interviewer

In my project We are  Using  Data Driven Framework Say like ::
Basically  I involved 3 stages- 
 1.Design the framework::
( eclipse create a java project by name abc,under project create like 
      project name---->package name---->class name--->,)
add all external jar file selenium,Apache POI jars,and TestNG Framework add all jars
To perform the validation, we create one more class Assertion. Whenever we need to perform validation we need to call assertText() or assertTitle() present under the Assertion class. (Assert.assertEquals())
 2.implementing the framework ::

This is where actual implementation of the framework start. While going thru the manual testcases we note down the common repeated steps and make those steps as a project specific methods. Even if one step is repeating , may be in same testcase or other testcase make it as a method. Then write the test script for all the manual test cases.

 

3.execution process ::

Right click on the project, navigate to TestNG → convert to TestNG → give the proper suite name and test name and click on finish. Then execute this xml file (ctrl+f11) or right click and run as TestNG Suite. Or to run thru cmd → navigate till project then give this commnd-

4.check failed testcase and execute agian


what is uses data driven in your project

Well defined architectural design
Less time to test large data
Script execution in multiple environments
Easier, faster, and efficient analysis of result logs
Communication of results

Easy debugging and script maintenance

Data Driven framework-------->

In my Project  is  too deep with pages , however each page can have scenarios that need to be tested with large test data sets, we would want to write automation scripts with a focus on test data aka. data-driven. Tools like Selenium already have excel sheet parsing etc that loops through rows and the same test case is executed for each data-set. It helps me to  excel is the most optimum way to handle test data.

Execute Failed test cases using selenium Real-time Example

Most of the time we have faced this question in interviews that Can we execute only failed test cases in Selenium or can we identify only failed test cases in Selenium and re-run them.



I really love this feature of TestNG that you can run only failed test cases explicitly without any code. This can be easily done by running one simple testng-failed.xml.


                                    Execute Failed test cases using Selenium

                                           Real-time Example

Take an example that you have one test suite of 100 test cases and once you start execution of test suite there  are a number of chances that some test cases will fail.Consider 15 test cases are failing out of 100 now you need to check why these test cases are failing so that you can analyze and find out the reason why they have failed.

Note- Your script can fail due to so many reasons some of them are

1- Some locator has been changed in application because the application is getting new feature- so in this case you need to modify your script in other words you have to refine your script.

You can not avoid maintenance of test script you always have to maintain your scripts
2- Either functionality has been broken- in this case, you have to raise a defect and assign to the respective person.

Execute Failed test cases using Selenium
Steps

1-If your test cases are failing then once all test suite completed then you have to refresh your project . Right click on project > Click on refresh or Select project and press f5.

2-Check test-output folder, at last, you will get testng-failed.xml

3- Now simply run testng-failed.xml.

           

How to run testng-failed.xml
We don’t have to perform any other activity once you will  get testng-failed.xml double click on this and analyze which test case are failing and why . Then modify your script and run it.

To run above xml simple right click on xml then Select run as then TestNG Suite.

How to create dependency between testcases in Selenium

How to create dependency betweentestcases in                               Selenium

I am sure you must be confused with Title like How to create a dependency between test cases in Selenium but in this post we will see this through example.

In real time, you will come across many situation where you have to create test cases which are dependent on the previous test case.

Take an example I have 3 test case.

First one which verify login credential and start application
Second test case check some validation  or do some activity
Third test case simply just for log-out activity.

If my first test case does not work (failed) that it does not make any sense to run second and third test case so in these type of scenarios you can use dependency between test case.

How can I do this?

TestNG already comes with this features so you can use the same with @Test annotations


Syntax- @Test(dependsOnMethods={"loginTestCase"})

public void testAccount()
{

// sample code

}
Syntax- @Test(dependsOnMethods={"loginTestCase"})

public void testAccount()
{

// sample code

}
How to create dependency between test cases in Selenium



It means this test case name testAccount depends on test case whose name is loginTestCase so until loginTestCase will not execute successfully this test case won’t execute so if loginTestCase will pass this test case will execute and if loginTestCase will fail then this test case won’t execute and runner will skip this test cases and this test case will come under skip test cases.

Let’s implement the same


package Demo;

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestMultiple {

@Test
public void testLogin()
{

System.out.println("login done");

}

@Test(dependsOnMethods={"testLogin"})
public void testAccount()
{
System.out.println("Account has been created");

}

@Test(dependsOnMethods={"testLogin","testAccount"})
public void testLogout()
{
System.out.println("logout");

}

}


package Demo;

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestMultiple {

@Test
public void testLogin()
{

System.out.println("login done");

}

@Test(dependsOnMethods={"testLogin"})
public void testAccount()
{
System.out.println("Account has been created");

}

@Test(dependsOnMethods={"testLogin","testAccount"})
public void testLogout()
{
System.out.println("logout");

}

}


In the above scenario if testLogin will pass then only testAccount will execute and testLogout will only execute of testLogin and testAccount will  be executed

but if testLogin will fail due to some error or exception the testAccount will not be executed and this test case will skip and testLogout is dependent on testLogin and testAccount so now this will also come into skipped category

Let’s implement again


import org.testng.Assert;
import org.testng.annotations.Test;

public class TestApplication {

@Test
public void testLogin()

{
Assert.assertEquals("Selenium", "Selnium");
System.out.println("login done");

}

@Test(dependsOnMethods={"testLogin"})
public void testAccount()

{
System.out.println("Account has been created");

}

@Test(dependsOnMethods={"testLogin","testAccount"})

public void testLogout()

{
System.out.println("logout");
}
}

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestApplication {

@Test
public void testLogin()

{
Assert.assertEquals("Selenium", "Selnium");
System.out.println("login done");

}

@Test(dependsOnMethods={"testLogin"})
public void testAccount()

{
System.out.println("Account has been created");

}

@Test(dependsOnMethods={"testLogin","testAccount"})

public void testLogout()

{
System.out.println("logout");

}
}


Output

FAILED: testLogin
java.lang.AssertionError: expected [Selnium] but found [Selenium]
at org.testng.Assert.fail(Assert.java:94)
SKIPPED: testAccount

How to capture screenshot for failed test cases in Selenium Webdriver

How to capture screenshot for failed test cases in Selenium Webdriver

Writing Selenium Webdriver script is not enough everyone can design script nowadays. We need to design script in such a way that we can utilize script code as much as possible.This article will talk about Capture screenshot in selenium for failed test cases.

I am a big fan of screenshots in Automation because it helps me a lot to identify the exact issue.

Generally, scripts fail in 2 situations.

1-If script has some issue (some locator has been changed or application has some changes)- In this case, we need to maintain our Selenium script.

2-Due to application issue- In this case, we need to inform to respective point of contact (Manual Tester or Developer)

How to Capture screenshot in selenium for failed test cases

Previously I have covered a post on capture screenshot in Selenium so if you have not gone through the previos post then I will highly recommend you to please go through the post and youtube as well.

Today we will see something different How to capture a screenshot for failed test cases in Selenium Webdriver.

Here I will be using two new topics which will help us to achieve the same.

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

Please refer official doc for ITestResult

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

Please refer official doc for @AfterMethod

If you are new to TestNG and want to explore more on TestNG then I will recommend you to please go through below TestNG topics.

I have covered a couple of topics for TestNG. You can check all TestNG Tutorial here

Now let’s get started and will see through a complete program

// Create a package in eclipse

package captureScreenshot;

// Import all classes and interface

import java.io.File;

import library.Utility;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.By;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.ITestResult;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.Test;

public class FacebookScreenshot {

// Create Webdriver reference

WebDriver driver;

@Test

public void captureScreenshot() throws Exception

{

// Initiate Firefox browser

driver=new FirefoxDriver();

// Maximize the browser

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

// Pass application url

driver.get("http://www.facebook.com");

// Here we are forcefully passing wrong id so that it will fail our testcase

driver.findElement(By.xpath(".//*[@id='emailasdasdas']")).sendKeys("jaganthota");

}

// It will execute after every test execution 

@AfterMethod

public void tearDown(ITestResult result)

{

// Here will compare if test is failing then only it will enter into if condition

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

{

try 

{

// Create refernce of TakesScreenshot

TakesScreenshot ts=(TakesScreenshot)driver;

// Call method to capture screenshot

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

// Copy files to specific location here it will save all screenshot in our project home directory and

// result.getName() will return name of test case so that screenshot name will be same

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

System.out.println("Screenshot taken");

} 

catch (Exception e)

{ 

System.out.println("Exception while taking screenshot "+e.getMessage());

} 

}

// close application

driver.quit();

}

}

Above code will execute fine and if test case will fail it will capture the screenshot. Check below screenshot

                                       

Above code is fine but still we need to enhance our code so that we can reuse.

We will create Utility class which will have one method which will capture the screenshot.

Code to create method for screenshot

package library;

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;

public class Utility 

{

public static void captureScreenshot(WebDriver driver,String screenshotName)

{

try 

{

TakesScreenshot ts=(TakesScreenshot)driver;

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

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

System.out.println("Screenshot taken");

} 

catch (Exception e)

{

System.out.println("Exception while taking screenshot "+e.getMessage());

} 

}

}
