PageFactory in Webdriver

In this article i will try to show you how to user PageFactory of webdriver.



1. Declare a class having webelement fields.
 
public  class GooglePage
{
   WebElement q; //q should be either name or id of the locator.
 
   void search()
  {
    q.sendeys("this is webdriver");
    q.submit();
  }

}

2.  Initialize above class other wise q will throw null pointer exception
  
  public class GoogleSearch
 {
   public static void main(String []arg )
  {
  
    WebDriver  driver=new FirefoxDriver()
     driver.get("http://www.google.com");
    GooglePage gp=PageFactory.initElements(driver,GooglePage.class);
    gp.search();
    
  }
 }

*   GooglePage gp=PageFactory.initElements(driver,GooglePage.class); : This line will initilize the q object of GooglePage.


You can rewrite above GooglePage class by using @FindBy annotation. Using annotation you can specify which locating technique you are using , it could be complex xpath,name,id...etc.  The example is below:

public  class GooglePage
{
  @FindBy(how=How.xpath,using="//input[@name='q']") 
   WebElement googleSearchElement;

   void search()
  {
    googleSearchElement.sendeys("this is webdriver");

    googleSearchElement.submit();

  }



}
