I've created different classes for each webpage using TestNG. My first class is working fine but the second class is throwing Null Pointer Exception. The same script if I combine in only one class It's working without any issues.
Below is my baseclass
package Test;
import org.testng.annotations.Test;
import Pages.FM_login;
import org.testng.annotations.BeforeTest;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.AfterTest;
public class Baseclass {
WebDriver driver;
FM_login objLogin;
#BeforeTest
public void setup() {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\****\\Downloads\\chromedriver.exe");
String url = "http://vatlookup.cloudfront.net";
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get(url);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
String Title = driver.getTitle();
System.out.println(Title);
System.out.println("Application Launch successful");
// Accept the cookie policy
driver.findElement(By.xpath("//a[#class='cc-btn cc-allow']")).click();
}
#Test
public void Login() {
objLogin = new FM_login(driver);
objLogin.GoToLoginScreen();
objLogin.loginToFleetMatch("abc", "123");
System.out.println("Login Successful");
}
#AfterTest(enabled=false)
public void teardown() {
driver.close();
}
This is another class
package Test;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;
import Pages.FM_Profile;
public class Profile {
WebDriver driver;
FM_Profile objProfile;
#Test
public void Skip_Tutorial() {
objProfile = new FM_Profile(driver);
driver.getCurrentUrl();
objProfile.SkipTutorial();
}
#Test(enabled=false)
public void edit_profile() {
objProfile.edit_profile();
}
}
below is the page object for a second class
package Pages;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class FM_Profile {
WebDriver driver;
By company_name = By.xpath("//p[#id='company-name']");
By plan_details = By.xpath("//p[#id='current-plan']");
By End_tour = By.xpath("//button[#class='driver-close-btn']");
By edit_profile = By.xpath("//span[contains(text(),'Edit')]");
By Description = By.xpath("//textarea[#id='mat-input-10']");
By Upload_image = By.xpath("//div[#class='upload-btn continental-book ng-star-inserted']");
By Save_profile = By.xpath("//button[#class='save-btn continental-book mat-stroked-button mat-button-base mat-primary editMode cdk-focused cdk-mouse-focused']");
public FM_Profile(WebDriver driver) {
this.driver = driver;
}
public void SkipTutorial() {
driver.findElement(End_tour).click();
}
after executing it's showing java.lang.NullPointerException for second class

In your Profile class the driver object is not initialized. The driver object that you are initializing is in BaseClass and instance of that class. You need to initialize driver object in Profile class as well
WebDriver is never initialised.
WebDriver driver = new WebDriver();

Browser Class

loginpage Class
public class loginpage {
WebDriver driver;
public loginpage(WebDriver driver)
{
this.driver=driver;
PageFactory.initElements(driver, this);
}
#FindBy(xpath="//*[#id=\"txtUserId\"]")
WebElement loginid;
#FindBy(xpath="//*[#id=\"txtPassword\"]")

}
public WebElement userPassword(){

Place_Order Class
public class Place_Order extends Browser{
WebDriver driver;
#Test
public void Place_Reservation() throws Exception
{
loginpage raku = PageFactory.initElements(driver, loginpage.class);
raku.userid().sendKeys("fp-ifttest");
raku.userPassword().sendKeys("ift");
}
}
Modify the code in the test class, as you are not initializing the driver correctly and also call the constructor of the pageobject instead.
#Test
public void Place_Reservation() throws Exception
{
**loginpage raku = new loginpage(Browser.driver);**
raku.userid().sendKeys("fp-ifttest");
raku.userPassword().sendKeys("ift");
}
Also try to follow Java naming standards like using capitals as starting for class names etc.
I have Test base class which calls a method from LandingPage class which has the locator for the page under test. When I execute this project, I'm getting Null pointer exception. I'm sure it has something to do with testNG annotations, but I'm unable to find out the reason.
package com.xyz.tests;

import org.openqa.selenium.firefox.FirefoxDriver;

import engine.Engine;
public class LandingPageTest {
public WebDriver driver;
//Engine engine = new Engine(driver);
LandingPage landingPage;
LoginPage loginPage;
#BeforeTest
public void setUp(){
driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get("https://www.go.com");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
}
#Test
public void clickOnSignInLink() {
landingPage.SignIn().click();
}
Below is my LandingPage class
package com.xyz.pageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class LandingPage {
private WebDriver driver;
public LandingPage(WebDriver driver) {
this.driver = driver;
}
//By signIn= By.xpath(".//*[#id='pageContainerInner']/div[2]/div[1]/div/div[2]/div[1]/a");
By signInBtn = By.linkText("Sign In or Create Account");
//By signInBtn2 = By.cssSelector("css=a.signIn");
By closeCrisisMessage = By.xpath(".//*[#id='closeCrisisMessageBtn']");
public WebElement SignIn(){
return driver.findElement(signInBtn);
}
}
Following is the error message

Any suggestions will be appreciated.
I'm not sure on what line your NullPointerException is thrown, but I would expect this to fail because your landingPage has not been initialized when the #Test method is run:
landingPage = new LandingPage(driver);
I see, you didn't instantiate landingPage & loginPage anywhere. That's why you are getting a null pointer exception. To get around this issue, you have to instantiate those references (mainly, landingPage here). Instantiate it either in place of declaration or in #BeforeClass annotation.
I'm trying to get a hang of PageFactory POM, however something is not working and I can not understand what is wrong.
This is my first POM class for Home Page:
package PageFactory;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
public class Home_Page_POF {
public WebDriver driver;
#FindBy(css = "div#header-profile a#header-profile-toggle")
public WebElement profileToggleButton;
#FindBy(css = "form#loginUserdataForm div.footer div.add-footer a.btn.btn-link.linkicon")
public WebElement newRegistrationButton;
public Home_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
}
}
This is the second POM class for the Reg. page
package PageFactory;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.Select;
public class Registration_Page_POF {
public WebDriver driver;
//Personal details WebElements
#FindBy(css = "form#personalDetailsForm div.profile.pe div.profile-block.simple.first fieldset#pefield-title select#pesalutation")
public WebElement titleDropdown;
public Select titleSelect = new Select(titleDropdown);
public Registration_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
}
}
And this is the test case:
package Tests;
import PageFactory.Home_Page_POF;
import PageFactory.Registration_Page_POF;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.io.TemporaryFilesystem;
import org.openqa.selenium.support.ui.Select;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
import java.util.concurrent.TimeUnit;
public class Test_POF {
public WebDriver driver;
Home_Page_POF objHomePage;
Registration_Page_POF objRegPage;
#BeforeClass
public void browserSetUp() {
System.setProperty("webdriver.chrome.driver", "D:/Install/selenium-2.53.0/drivers/chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.navigate().to("http://www.lufthansa.com/");
}
#AfterClass
public void broserCleanUp() {
if (driver != null) {
TemporaryFilesystem.getDefaultTmpFS().deleteTemporaryFiles();
driver.close();
driver.quit();
}
}
#Test
public void Test0001() {
objHomePage = new Home_Page_POF(driver);
objHomePage.profileToggleButton.click();
objHomePage.newRegistrationButton.click();
objRegPage = new Registration_Page_POF(driver);
Select titleSelect = new Select(objRegPage.titleDropdown);
titleSelect.selectByVisibleText("Mr.");
}
}
So the HomePage objects are working fine, I click on two buttons and proceed to registration page.
After that I want to select a value from dropdown, but it gives me NullPointerException:

The Problem is you are initializing the varaible titleSelect in class itself. Just Initialize inside constructor or after finding the element;
public class Registration_Page_POF {
public WebDriver driver;
//Personal details WebElements
#FindBy(css = "form#personalDetailsForm div.profile.pe div.profile-block.simple.first fieldset#pefield-title select#pesalutation")
public WebElement titleDropdown;
public Select titleSelect; //Dont initialize here
public Registration_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
titleSelect = new Select(titleDropdown);//initialize here
}
}
I am getting following error when I run code in Selenium and Java using TestNG. On multiple blogs/sites it is mentioned to clean the project and so I did Project->Clean but still it is throwing me this error. Can some one please point me what is wrong in this code? Thanks.

iam facing a problem i have written a method navback, which i need to use regularily to navigate back. when iam running it is throwing a error.

Please some one help me, iam not able to proceed further.

You don't initialize driver, so it is null, but you pass it to Actions.
public static WebDriver driver;
Actions action = new Actions(driver);
That throws a NullPointerException.

Initialize driver.
Note the lifecycle. Before JUnit runs your #BeforeClass or #Before methods, it has to create the Flipkart instance. The instance field initialization expression runs at that point.
Rethink your design. Initialize action after driver has been initialized.
