Page Object Model (POM) & Page Factory in Selenium

Page Object Model | POM

Creating Selenium test cases can result in an unmaintainable project. One of the reasons is that too many duplicated code is used. Duplicated code could be caused by duplicated functionality and this will result in duplicated usage of locators. The disadvantage of duplicated code is that the project is less maintainable. If some locator will change, you have to walk through the whole test code to adjust locators where necessary. By using the page object model we can make non-brittle test code and reduce or eliminate duplicate test code. Beside of that it improves the readability and allows us to create interactive documentation. Last but not least, we can create tests with less keystroke. An implementation of the page object model can be achieved by separating the abstraction of the test object and the test scripts.

·          Count and print no. of links present on webpage using Page Object Model

1.    In order to initialize the elements which are declare using @FindBy. We use initElements method of Page Factory Class

import java.util.List;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.support.FindBy;

import org.openqa.selenium.support.PageFactory;

public class Flipkartpage

{

   @FindBy(xpath="//a")

   private List<WebElement> allLinks;

  

   public Flipkartpage (WebDriver driver)

   {

          PageFactory.initElements(driver,this);

   }

   public void PrintNoofLinks()

   {

          //To count no. of links present on webpage

          System.out.println(allLinks.size());

          for (WebElement pagelink : allLinks)

          {     

                 String linktext = pagelink.getText();

                 String link = pagelink.getAttribute("href");

                 System.out.println(linktext+" ->");

                 System.out.println(link);

          }

   }

}

2.   Now create the class of Main method

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class POM

{

   public static void main(String[] args)

   {

          WebDriver driver=new FirefoxDriver();

          driver.get("Page Url");

          Flipkartpage f=new Flipkartpage(driver);

          f.PrintNoofLinks();

          driver.close();     

   }

}
