Hello All,

I have read about Page Object and Page factory and tried to implement the
same in my selenium automation script. But i am getting an Instantiation
Exception though I have tried all means to correct them.
It would be great if someone can help me where am doing mistake.

Also en early response towards solving this would be highly helpful.

*My Page objects are as follows :: *http://pastebin.com/X1kNDWA5

*My Test using Page Object are as follows :: *http://pastebin.com/KZKJ9CKL

*The Error that I get on executing ::*

PageObject must be initiated before you can use it, you are doing it the
other way around. :

public class LoginPage {

private RemoteWebDriver driver;

public LoginPage(RemoteWebDriver driver){
this.driver = driver;
PageFactory.initElements(driver, LoginPage.class);
}

@FindBy(name = "Email")
public WebElement EmailField;

@FindBy(xpath =
"//linear[1]/window[1]/relative[1]/relative[1]/window[1]/linear[1]/linear[1]/linear[1]/linear[1]/textfield[2]"
)
public WebElement PasswordField;

@FindBy(name = "Sign in")
public WebElement SigninBtn;

public LoginPage login(String emailAddress, String password) throws
InterruptedException {

this.EmailField.sendKeys(emailAddress);
this.PasswordField.sendKeys(password);
this.SigninBtn.click();
return this;
}

}

Test:

@Test
public void Test() throws InterruptedException {

LoginPage loginpage = new LoginPage();
loginpage.login("qa_user150214-***@public.gmane.org", "test");

}

Ok, my fault,
PageFactory.initElements(driver, LoginPage.class);
does return a new instance of that class given as 2nd parameter. I always
just call it from page constructor. sry.

Not true, have a look at lines 65-69 of
