How to pass selenium webdriver object to another class

Test Automation

In Selenium test script it is required to use or perform an action on current driver instance of browser(Chrome, IE, firefox etc).

it is therefore required to use the same driver object if the driver usage requirement in another class. How to pass it or how to get that same object in another class(java- considering scripting in java).

How to do it-using constructor and inheritance

package Seleniumclasses;
import org.openqa.selenium.WebDriver;
public class Webdriverdefinition {
public static WebDriver driver = null;

public Webdriverdefinition()
if(driver == null)
String chromepath;
chromepath = “./chromedriver”;
System.setProperty(“”, chromepath+”.exe” );
driver = new ChromeDriver();
System.out.println(“**Chrome driver initiated**”);
System.out.println(“**Chrome driver already instantiated**”);


public static WebDriver getdriver()
if (driver == null){

return driver;
return driver;



class 2- where Class1(Webdriverdefinition) has been extended, using extend has automatically constructor which defining object. In @Test method Login getdriver is being called which is getting driver from class –

In class 2 chrome driver is being launched and google search has been opened, Test has been entered in text box and button has been clicked.

1(Webdriverdefinition class)

package Seleniumclasses;
import org.openqa.selenium.By;
import org.testng.annotations.Test;

public class WebInteraction extends Webdriverdefinition

public void login()
getdriver().findElement(“lst-ib”)).sendKeys("Test Automation”);


It is recommended to use same driver instance inside your test scripts, and to pass the driver instance across different class/methods there are couple of other ways to declare and pass driver object which i will publish in next post. Keep reading for the same.
