RE: Not able to use EventFiringWebDriver object in child class

I am try to set up EventFiringWebDriver in my poject, I am stuck up at some point where EventFiringWebDriver object is working fine in the same class & not working in the child class.

Parent class:

package utility;

import java.util.List;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.events.EventFiringWebDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;

import eventListeners.WebDriverEventHandler;

public class common {
public static WebDriver driver = null;
protected static EventFiringWebDriver eDriver;
WebDriverEventHandler handler;
protected NavigatetoOverviews nav;

@BeforeClass
public void beforeClass() throws InterruptedException {

handler = new WebDriverEventHandler();
System.setProperty(“webdriver.firefox.profile”, “default”);
driver = new FirefoxDriver();
eDriver = new EventFiringWebDriver(driver);
eDriver.register(handler);

nav = new NavigatetoOverviews();
eDriver.get(“http://google.com”);
}
}
My child class:

package eventListeners;

import java.util.concurrent.TimeUnit;

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

import bsh.commands.dir;
import utility.common;

public class TestExtendsCommon extends common{

@Test
public void sample() {

eDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
eDriver.findElement(By.id(“gbqfq”)).sendKeys(“Selenium”);
eDriver.findElement(By.id(“gbqfba”)).click();

}
}
My Test Results:

[TestNG] Running:
C:\Users\Hema\AppData\Local\Temp\testng-eclipse–492139263\testng-customsuite.xml

I even tried to return the eDriver from class1 & tried to use that in Class2. In this scenario also getting the same error.

Hi
I Guess This is The problem
you are initializing your Webdriver in @beforeClass they got initialized before Class
But When Class Code is Running It is Setting There Values to Null

You Just Try Doing Same Thing With @before

i Hope It will work
