Page Object Model in Selenium

Page Object Model in selenium :

POM : Page object model is an object / element design pattern to create repositories for web elements.

Example : Link, Button, Edit box etc.

-> For centralised maintenance of object/elements we create repositories.

Under this model contains classes for web elements are created that behave as as object repories.

We can create page object model in two ways :

1- Page object model,

2- Page object model with page factory.

Page object model :

Page object model without page factory :

No object repository facility in selenium web driver . It is a programing interface . In UFT / QTP we have object repository facility (Local and shared object repository).

-> Under this model for each website in the application, there should be corresponding page class.

-> This page class will find the web elements of the web page and also contains the methods which perform operation.

If no object repository / Our tag object model then it is difficult to maintain objects or elements in testcases.

Advantages of POM :

1- Reusability of elements, reduces code size.

2- It is efficient and scalable .

3- Easy maintenance of elements/objects.

Implement Page object model :

In this approach all page components of the application and client activities on those web components are kept up as strategies inside a class document, by bringing in the page class, we can make testcases.

Create page class :

Requirements – create a page class / object repository using some elements.

(uername, password, login button, error message , only catelog the etc.... )

Create test cases :

login, verify error message, verify re direction.

Example :

package com.amave.com.test;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

public class LoginPage 
{
	WebDriver driver;

    By userName = By.name("uid");

    By password99Guru = By.name("password");

    By titleText =By.className("barone");

    By login = By.name("btnLogin");

    

    public void Login(WebDriver driver){

        this.driver = driver;

    }


    public void setUserName(String strUserName){

        driver.findElement(userName).sendKeys(strUserName);

    }


    public void setPassword(String strPassword){

         driver.findElement(password99Guru).sendKeys(strPassword);

    }

    public void clickLogin(){

            driver.findElement(login).click();

    }

    public String getLoginTitle(){

     return    driver.findElement(titleText).getText();

    }

   

    public void loginToGuru99(String strUserName,String strPasword){

        
        this.setUserName(strUserName);

        
        this.setPassword(strPasword);

       
        this.clickLogin();        

}
}
