Using PageFactory and TestNG, calling PageFactory getting error

[Partho Dutta]

Here is my code
This the Driver class where i have initialized Chrome Driver
public class Driver {
   
   
    public static  WebDriver driver;
    }

This is my Login Class where i have accessed PageFactory elements

public class Login {
 
    //PageFactory Web elements Accessed
    LoginPage loginPage=PageFactory.initElements(Driver.driver,LoginPage.class);
    WaitLib waitLib=new WaitLib();
   
   
    public void LoginToApp(String userName, String password,String url) throws IOException
    {
        try
        {
                   
        Driver.driver.manage().window().maximize();
        Driver.driver.get(url);
         loginPage.getUsername().sendKeys(userName);
         loginPage.getPassword().sendKeys(password);
         loginPage.getLogIn().click();
          waitLib.implicitWait();
        }catch(Exception e)
        {
            e.printStackTrace();
        }
       
    }

}

 This is my TestNG Code

public class CreateCompanyTest {
    ExcelLib excelLib;
    Login login;
   

    @BeforeClass
    public void configBeforeClass() throws Exception {

        // Object intialization
        excelLib = new ExcelLib();
        login = new Login();
        System.setProperty("webdriver.chrome.driver", "Driver/chromedriver.exe");
        Driver.driver=new ChromeDriver();
        
    }

    @BeforeMethod
    public void configBeforeMethod() throws Exception {
        
        
        
        String url = excelLib.getExcelData(1, 0, "Data1");
        System.out.println("------URL-----"+url);
        String userName = excelLib.getExcelData(1, 1, "Data1");
        System.out.println("------userName-----"+userName);
        String password = excelLib.getExcelData(1, 2, "Data1");
        System.out.println("------password-----"+password);
        login.LoginToApp(userName, password, url);
        Thread.sleep(3000);
        System.out.println("Hellol");

    }

    @Test
    public void createCompanyTest() {
        System.out.println("Hi");

    }

}

When i am running TestNG Code i am getting error like   
   java.lang.NullPointerException
    at org.openqa.selenium.support.pagefactory.DefaultElementLocator.findElement(DefaultElementLocator.java:69)
    at org.openqa.selenium.support.pagefactory.internal.LocatingElementHandler.invoke(LocatingElementHandler.java:38)
    at com.sun.proxy.$Proxy6.sendKeys(Unknown Source)
    at businesslogic.Login.LoginToApp(Login.java:37)
    at testcases.CreateCompanyTest.configBeforeMethod(CreateCompanyTest.java:45)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

Partho,

Can you please try changing 

@BeforeClass

public void configBeforeClass() throws Exception {

    // Object intialization

    excelLib = new ExcelLib();

    login = new Login();

    System.setProperty("webdriver.chrome.driver", "Driver/chromedriver.exe");

    Driver.driver=new ChromeDriver();    

}

To

@BeforeClass

public void configBeforeClass() throws Exception {

    // Object intialization

    System.setProperty("webdriver.chrome.driver", "Driver/chromedriver.exe");    

    excelLib = new ExcelLib();

    Driver.driver=new ChromeDriver();    

    login = new Login();

}

and try again ?

Explanation : When you instantiate the Login() page it also ends up invoking the PageFactory.initElements() method [thats how you have written your code ] but with a null WebDriver object because Driver.driver is still not set a valid object.

I have just flipped the order of statements in your @BeforeClass annotated method such that first the driver gets instantiated and initialised in your Driver class and only then you instantiate the Login() object.

Thanks & Regards
