What is Cross Browser Testing in TestNG

                               What is Cross browser testing            
Cross browser, testing refers to testing the application in multiple browsers like IE, Chrome, Firefox so that we can test our application effectively.IE, Chrome, Firefox so that we can test our application effectively.

Cross browser, testing is very important concept in Automation because here the actual automation comes into the picture.

Example- Suppose if you have 20 test cases that you have to execute manually, so it is not a big deal right we can execute in 1 day or 2 days. However, if the same test cases you have to execute in five browsers it means 100 test cases then probably you will take one week or more than one week to do the same and it will be quite boring as well.

If you automate these 20 test cases and run them then it will not take more than one or two hour depends on your test case complexity.

Cross Browser Testing using Selenium Webdriver

To achieve this we will use TestNG parameter feature, we will pass parameter from TestNG.xml file, and based on our parameter Selenium will initiate our browsers.

In this scenario, we will run the same testcase with two different browser parallel.

Step 1- Write testcase
---------------------------------

package SampleTestcases;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class TestCase1 {

@Test

// Here this parameters we will take from testng.xml
@Parameters("Browser")
public  void test1(String browser) {

if(browser.equalsIgnoreCase("FF")){

WebDriver driver=new FirefoxDriver();

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

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

driver.quit();

}
else if(browser.equalsIgnoreCase("IE")){

System.setProperty("webdriver.ie.driver", "./server/IEDriverServer.exe");

WebDriver driver=new InternetExplorerDriver();

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

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

driver.quit();
}
}

}
 Step 2- Create testng.xml and specify
------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
Here parallel is an attribute which specify the mode of execution and thread-count specify how many browser should open
<suite name="Suite" parallel="tests" thread-count="2">

<test name="Test">

<parameter name="Browser" value="FF" />

<classes>

<class name="SampleTestcases.TestCase1"/>

</classes>

</test>

<test name="Test1">

<parameter name="Browser" value="IE" />

<classes>

<class name="SampleTestcases.TestCase1"/>

</classes>

</test>

</suite>
Step 3- Run this xml file refer the below screenshot
------------------------------------------------------

Note- To create testng.xml- Right, click on your testcase then go to TestNG then convert to TestNG> It will generate testng.xml then make changes as per above xml file and finish. You will get testng.xml file inside the project

Different ways to get all "404 page not found" links using Selenium WebDriver

     Different ways to get all "404 page not found" links         

In this post, I will explain the most convenient way using Selenium WebDriver to get all the links from web page and verifying each page contains specific like 404 or Page not found in different ways.

//Following ways to identify 404 links

By using page title

By using page source

By using response code of page URL     

  

Please find the below code for the same.

Sample Code:

import java.io.IOException;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

import java.util.ArrayList;

import java.util.List;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Test;

public class GetAllLinks {

 public WebDriver driver;

 ArrayList<String> al ;

 @BeforeClass

 public void setup(){

  driver = new FirefoxDriver();

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

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

  

 }

 @Test

 public void identifyBrokenAnd404Links() throws MalformedURLException, IOException{

  

      al = new ArrayList<String>();

  

    //identifying total number of URls in a page

    List<WebElement> links = driver.findElements(By.tagName("a")); 

    System.out.println(links.size());

   

           //for Getting all links from page

          for (int i = 0;i<links.size(); i++) {

      

        //get one by one URL href value

        String URL=links.get(i).getAttribute("href"); 

       

        //Removing unwanted URLS based on http or https

        if(links.get(i).getAttribute("href").contains("https")||links.get(i).getAttribute("href").contains("http"))

        {

        System.out.println(URL);

       

         //storing all in URL's in array list

         al.add(URL);

       

        }

          }

     

          //Identifying  broken and 404 links

         

          for(int i=0;i<al.size();i++){

           

           //Navigating each URL

           driver.get(al.get(i));

           

           //getting response Code for the link

           int statusCode= ResponseCode(al.get(i));

           //verifying 404 links using page title

           

           if(driver.getTitle().contains("404")){

            

            System.out.println("404 link is  "+al.get(i));

            

           }

           

           //verifying 404 links using page source

           else if(driver.getPageSource().contains("404 page not found")){

            

            System.out.println("404 link is  "+al.get(i));

            

           }

           //verifying 404 links using status code

           else if(statusCode==404){

            

            System.out.println("404 link is  "+al.get(i));

           } 

           

           

          } 

  }

    //method for generating response code for URL

     public static int ResponseCode(String URL) throws MalformedURLException, IOException {     

        URL url = new URL(URL); 

        HttpURLConnection huc = (HttpURLConnection) url.openConnection(); 

        huc.setRequestMethod("GET"); 

        huc.connect(); 

        return huc.getResponseCode(); 

     } 

}

              

Data Driven Framework in Selenium Webdriver

             Data driven framework in selenium web driver 

this framework purely depends on data and data source can be anything like Excel file, CSV File, database.

In data driven framework script will be separated from Data part, it means so if any changes happen we do not have to modify all the test cases.

Example-
I have to create 50 Gmail accounts so I have two approaches to do this

First- I can create 50 scripts and run them.

Second- I can keep all data separate in the file and changes the data only that is required for script and script will be only one. In future, any changes in my application then I have to modify my one script only not fifty.

In simple words when we have to execute same script, multiple sets of data we will adopt data driven framework

In this post, we are taking data from 2D Array and feeding data into script

Scenario 1- Open Facebook and type username and password and login
this test case should run 2 times with different set of data(data we have provided in the 2D array)

Lest Implement the same

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestDDT {

// this will take data from dataprovider which we created
@Test(dataProvider="testdata")
public void TestFireFox(String uname,String password){

// Open browsre
WebDriver driver=new FirefoxDriver();


// Maximize browser
driver.manage().window().maximize();


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


// clear email field

driver.findElement(By.id("email")).clear();


// Enter usename
driver.findElement(By.id("email")).sendKeys(uname);

// Clear password field
driver.findElement(By.id("pass")).clear();


// Enter password
driver.findElement(By.id("pass")).sendKeys(password);
}
// this is DataProvider which actually feed data to our test cases here I have taken 2 D //array with 2 rows and 2 column it means. It will run our test case two times because we //have taken 2 rows. While first iteration this will pass username and password to test //case and in second iteration perform the same for second rows

@DataProvider(name="testdata")
public Object[][] TestDataFeed(){

// Create object array with 2 rows and 2 column- first parameter is row and second is //column
Object [][] facebookdata=new Object[2][2];

// Enter data to row 0 column 0
facebookdata[0][0]="Selenium1@gmail.com";


// Enter data to row 0 column 1
facebookdata[0][1]="Password1";


// Enter data to row 1 column 0
facebookdata[1][0]="Selenium2@gmail.com";

// Enter data to row 1 column 0
facebookdata[1][1]="Password2";

// return arrayobject to testscript
return facebookdata;
}

}</span>

Data driven framework in selenium webdriver using Excel files
In above post, we have seen data driven using 2D array but once your test data will increase then you have to switch to Excel or CSV or Database.

Create some test data in Excel that we will pass to the script. For demo purpose, I have to take username and password in Excel.
Before implement the program please make sure you are familiar with Reading Data from Excel.
Copy below program and before executing make sure following Thing configured correctly.

Eclipse, TestNG, JExcel jar
Scenario -Open Facebook and login with different username and password
username and password will be coming from excel sheet

Note- in below program we have 2 rows only so test case will execute 2 times with different data
package DataDrivenTesting;

import java.io.IOException;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestDDT1 {

WebDriver driver;
Workbook wb;
Sheet sh1;
int numrow;
String username;
String password;

@BeforeTest
public void Setup()

{
driver=new FirefoxDriver();
driver.manage().window().maximize();
driver.get("http://www.facebook.com");
}

@Test(dataProvider="testdata")
public void TestFireFox(String uname,String password1)

{

driver.findElement(By.id("email")).clear();
driver.findElement(By.id("email")).sendKeys(uname);
driver.findElement(By.id("pass")).clear();
driver.findElement(By.id("pass")).sendKeys(password1);
}

@DataProvider(name="testdata")
public Object[][] TestDataFeed(){

try {

// load workbook
wb=Workbook.getWorkbook(new File("location of excel sheet/fbdata.xls"));

// load sheet in my case I am referring to first sheet only
sh1= wb.getSheet(0);

// get number of rows so that we can run loop based on this
numrow=  sh1.getRows();
}
catch (Exception e)

{
e.printStackTrace();
}

// Create 2 D array and pass row and columns
Object [][] facebookdata=new Object[numrow][sh1.getColumns()];

// This will run a loop and each iteration  it will fetch new row
for(int i=0;i<numrow;i++){

// Fetch first row username
facebookdata[i][0]=sh1.getCell(0,i).getContents();
// Fetch first row password
facebookdata[i][1]=sh1.getCell(1,i).getContents();

}

// Return 2d array object so that test script can use the same
return facebookdata;
}

@AfterTest
public void QuitTC(){

// close browser after execution
driver.quit();
}

}</span>

I hope you have enjoyed the data driven framework in selenium webdriver and Hope you will implement the same. If you still have any doubt then let me know in the comment section. You can implement the same data driven framework using POM (Page Object model ) which will be the advanced version of data driven framework in selenium webdriver.
