TestNG.java.lang.NullPointerException running second @Test

Question

It runs first test, but then I'm getting null pointer exception when running Edit Profile test.
Not sure why.
I globally declared public driver.
Please help. Thanks

package test;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.BeforeTest;

import com.tapanalytics.config.Configuration;
import com.tapanalytics.pom.domain.analyticsEditProfilePage;
import com.tapanalytics.pom.domain.analyticsLandingPage;
import com.tapanalytics.pom.domain.analyticsLoginPage;

public class TestLogin {

public  WebDriver driver;// = new FirefoxDriver();
public String baseURL = "mytestsite.com";

@BeforeTest
 public void setBaseURL(){
   driver = new FirefoxDriver();
   driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);
   driver.get(baseURL);
}

//Login test
@Test
public void testLogin() throws InterruptedException{

    driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);

    analyticsLoginPage mylogin = PageFactory.initElements(driver, analyticsLoginPage.class);
    analyticsLandingPage landingpage = mylogin.login("username", "password");
    Thread.sleep(3000);
}

//Edit Profile test

@Test//(dependsOnMethods = { "testLogin" })
public void verifyProfile() throws InterruptedException{
    // driver = new FirefoxDriver();

    Thread.sleep(3000);
    analyticsLandingPage landingpage = new analyticsLandingPage();
    Thread.sleep(3000);
    landingpage.gotoProfile();



    //driver.findElement(By.xpath(".//*[@id='left-frame']/div/div[2]/a[3]/span")).click();
    //Thread.sleep(5000);
    analyticsEditProfilePage editprofile = PageFactory.initElements(driver, analyticsEditProfilePage.class);
    editprofile.verifyEditFirstName();
    editprofile.verifyEditLastName();
    editprofile.verifyCompanyName();
    editprofile.verifyReportingProfile();
    editprofile.verifyUsageStatistics();


    }

@AfterTest
public static void quitDriver(){
    driver.quit();
}

PASSED: testLogin

FAILED: verifyProfile

Can you show the code from the goToProfile() method?

There are two issues with your code.

The first:

It seems like you never apply the PageFactory on this class. Therefore, when trying the line profile.click() the variable is null (because never initialized). Hence your exception.

Solution: add the following line like you did for the other classes.

analyticsLandingPage landing = PageFactory.initElements(driver, analyticsLandingPage.class);

The second:

You are currently creating a new object like this:

analyticsLandingPage landingpage = new analyticsLandingPage();

However, you posted your class like this:

public class analyticsLandingPage 
{ 
     WebDriver driver; 

     public analyticsLandingPage(WebDriver driver){ 
          this.driver = driver; 
     } 

     @FindBy(xpath = Configuration.profile) 
     public WebElement profile; 

     public void gotoProfile(){ 
         profile.click();   
     } 
}

Problem: you are calling the default constructor of the class, in which the driver variable does not get initialized.

Solution: make sure you pass the parameter so you call the custom constructor.

analyticsLandingPage landingpage = new analyticsLandingPage(driver);

Might be your driver is not initialized in landingpage.gotoProfile();

Check in gotoProfile() method if driver is initialized, properly.

Things you can try

Pass the driver to gotoProfile() method, as shown below

landingpage.gotoProfile(driver);

and accepting argument in gotoProfile method as bellow

public void gotoProfile(WebDriver driver) {
// code of go to Profile
}

OR

While creating object of analyticsLandingPage class pass the driver as argument and write a constructor which will initialize the value of driver in analyticsLandingPage class, as shown below.

Creating object

analyticsLandingPage landingpage = new analyticsLandingPage(driver);

Initialize driver value in analyticsLandingPage class

public class analyticsLandingPage {

WebDriver driver;

public analyticsLandingPage(WebDriver driver) {
this.driver = driver;
}
 // Rest of analyticsLandingPage code
}

Edit Profile class

package com.tapanalytics.pom.domain;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

import com.tapanalytics.config.Configuration;

public class analyticsLandingPage {

          WebDriver driver;

       public analyticsLandingPage(WebDriver driver){
        this.driver = driver;
    }

@FindBy(xpath = Configuration.manage_dashboard)
public WebElement manage_dashboard;

@FindBy(xpath = Configuration.manage_services)
public WebElement manage_services;

@FindBy(xpath = Configuration.profile)
public WebElement profile;

@FindBy(xpath = Configuration.support)
public WebElement support;

@FindBy(xpath = Configuration.logout)
public WebElement logout;

public void gotoMangeDashboards(){
    manage_dashboard.click();
}

public void gotoServices(){
    manage_services.click();        
}

public void gotoProfile(){
    profile.click();    
}

public void gotoSupport(){
    support.click();    
}

public void Logout(){
    logout.click(); 
}


}

Thanks , I tried both options and still getting same error. Here is my goto Profile class. — jim, Commented Feb 12, 2016 at 19:22

public  WebDriver driver;// = new FirefoxDriver();
public String baseURL = "";

@BeforeTest
 public void setBaseURL(){
   driver = new FirefoxDriver();
   driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);
   baseURL ="https://www.mytestsite.com";
   driver.get(baseURL);
}

Please edit your answer to explain to the OP why your code will help. A code-only answer without any further information is not especially helpful, especially for a question as old as this one.

try using public static

public static webdriver driver in each class files

public static is not needed if you are running a single test case, but since in a suit where parallelization may occur for multiple cases, so public ststic is needed for multiple test cases

This depends on if you want to use it as a static class or not within the suite. Please improve your answer by explaining why this approach might help the questioner. What are the disadvantages?
