Data Driven Selenium Automation Testing using JXL (Part 2)

We learned what is Data-driven Selenium Automation testing and how we can use JXL to read data from Excel Sheets in Part 1 of our previous post. But the question that still needs to be addressed is, how to use JXL for data-driven testing? How to use this in the Selenium framework that already exists? What are the steps which have to be taken care of to make the framework a data-driven framework?

Well, for this let us not walk through the typical theoretical content that you can always find some way or other. But let’s do it with the real working code.

To perform data-driven selenium automation testing, all we need to do is create a reusable library file just for Excel using JXL. The library file needs to have the following basic functionality in hand.

How to use JXL for Selenium Automation Testing?

Step 1

Create a library file with all the below-mentioned functionality

1. Open Excel Sheet

2. Read Excel Sheet Row Count

3. Read Cell value from a specified location

4. Create a Dictionary to store Excel Sheet Column name

5. Create a function to read from the Dictionary

The Source code for selenium automation testing looks like this.

package DataDriver;
import java.util.Hashtable;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;

public class ExcelSheetDriver {

	static Sheet wrksheet;
	static Workbook wrkbook =null;
	static Hashtable dict= new Hashtable();
	//Create a Constructor
	public ExcelSheetDriver(String ExcelSheetPath) throws BiffException, IOException
		wrkbook = Workbook.getWorkbook(new File(ExcelSheetPath));
		//For Demo purpose the excel sheet path is hardcoded, but not recommended :)
		wrksheet = wrkbook.getSheet("Sheet1");

	//Returns the Number of Rows
	public static int RowCount()
		return wrksheet.getRows();

	//Returns the Cell value by taking row and Column values as argument
	public static String ReadCell(int column,int row)
		return wrksheet.getCell(column,row).getContents();

	//Create Column Dictionary to hold all the Column Names
	public static void ColumnDictionary()
		//Iterate through all the columns in the Excel sheet and store the value in Hashtable
		for(int col=0;col < wrksheet.getColumns();col++)
			dict.put(ReadCell(col,0), col);

	//Read Column Names
	public static int GetCell(String colName)
		try {
			int value;
			value = ((Integer) dict.get(colName)).intValue();
			return value;
		} catch (NullPointerException e) {
			return (0);



Next, we are going to create an actual test file that is going to perform the intended operation, here we are going to perform Gmail login functionality.

Step 2

Create a TestNG Class file to perform Gmail Login

This TestNG class file should include

1. Opening a browser with Gmail

2. Perform User Name and password entry with different combinations of value by reading from the Excel sheet

Then, check the source code. It should look like this.

package DataDriver;

 * Author : Karthik KK
 * Description: To perform Gmail Login using Data driven approach
 * Date : 01/28/2012


import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class ReadDataTest {

  //Global initialization of Variables
  static ExcelSheetDriver xlsUtil;
  WebDriver driver = new InternetExplorerDriver();

  //Constructor to initialze Excel for Data source
  public ReadDataTest() throws BiffException, IOException
		//Let's assume we have only one Excel File which holds all Testcases. weird :) Just for Demo !!!
	    xlsUtil = new ExcelSheetDriver("D:\Data.xls");
	    //Load the Excel Sheet Col in to Dictionary for Further use in our Test cases.

  public void EnvironmentalSetup()

   * Author : Karthik KK
   * Description : To Perform login operation in Gmail
  public void GmailLoginPage() throws InterruptedException {

	  //Create a for loop.. for iterate through our Excel sheet for all the test cases.
	  for(int rowCnt = 1;rowCnt < xlsUtil.RowCount();rowCnt++)

		  //Enter User Name by reading data from Excel
		  WebElement userName = driver.findElement("Email"));
		  userName.sendKeys(xlsUtil.ReadCell(xlsUtil.GetCell("EmailUserName"), rowCnt));

		  //Enter Password
		  WebElement password = driver.findElement("Passwd"));
		  password.sendKeys(xlsUtil.ReadCell(xlsUtil.GetCell("Emailpassword"), rowCnt));

		  //Click on the Sign In Button
		  WebElement signin = driver.findElement("signIn"));;

		  //Sleep for some time,so that we can see things in action @ Screen :)


Step 3

Create an actual Excel Sheet which holds the data to be supplied in the TestNG class in the above step

Just create an Excel sheet, which looks something like this.

Step 4

Try executing the code

So, it’s time now that you try executing the code. Note in the above code we have placed an excel sheet in D: drive. You can place it anywhere in the machine and change the same in code.

Then, your Gmail screen will look like this at the end of the test by executing all the above test data.
