WebDriver is not passing between classes using page factory

[David Purvis]

I am getting an error when accessing pages from another class.

java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.SearchContext.findElement(org.openqa.selenium.By)" because "this.searchContext" is null

at org.openqa.selenium.support.pagefactory.DefaultElementLocator.findElement(DefaultElementLocator.java:68)

at org.openqa.selenium.support.pagefactory.internal.LocatingElementHandler.invoke(LocatingElementHandler.java:38)

at jdk.proxy2/jdk.proxy2.$Proxy17.click(Unknown Source)

at Pages.InventoryListPage.getItemNames(InventoryListPage.java:31)

at StepDefinitions.CheckDataBetweenListAndSingleItemSteps.checkList(CheckDataBetweenListAndSingleItemSteps.java:19)

at ✽.check list item view against single item view(file:///C:/Users/purvisd/SwagLabs/SwagLabsFramework/src/test/resources/Features/checkSingleItem.feature:8)

This is the class I am calling from

package StepDefinitions;

import org.openqa.selenium.WebDriver;

import Pages.InventoryListPage;

import io.cucumber.java.en.Given;

import io.cucumber.java.en.Then;

public class CheckDataBetweenListAndSingleItemSteps {

WebDriver driver;

InventoryListPage inventory;

@Then("check list item view against single item view")

public void checkList() {

inventory = new InventoryListPage(driver);

inventory.getItemNames();

}

@Given("user is on the home page")

public void user_is_on_the_home_page() {

}

}

This is the page object class I am calling

package Pages;

import java.util.List;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.support.FindAll;

import org.openqa.selenium.support.FindBy;

import org.openqa.selenium.support.PageFactory;

public class InventoryListPage {

@FindAll(@FindBy(className="inventory_item_name"))

public List<WebElement> Item_Names;

@FindAll(@FindBy(className="inventory_item_price"))

public List<WebElement> Item_Price;

@FindBy(id="react-burger-menu-btn")

public WebElement burgerMenu;

public WebDriver driver;

public InventoryListPage(WebDriver driver) {

this.driver=driver;

PageFactory.initElements(driver, this);

}

public void getItemNames() {

System.out.println("I am in the Names constructor");

burgerMenu.click();

}

}

The site I use is a testing site at

https://www.saucedemo.com/

I think this is a passing WebDriver to another class issue because If I call all objects from the same class everything works if I call first from the login class then the list class i get the error message.

Any help or insight into this error will be gratefully received .

With thanks in advance.

Where are you instantiating WebDriver and assigning it to the data member in your test class ?
