POM
Framework:
In Page
Object Model framework, Object identification code and validation code are
separated
|
Package01
(Object Repository)
Class-1
{page01:
webelements identification code}
Class-2
{page02:
webelements identification code}
|
|
Package02
(TestCases)
{Validation
Code}
|
In this
approach we create individual classes for every page webelements with
identification code and then in each class we create individual functions for
each Webelement to return identification value for Webelement
Advantages
of POM:
-In future
or next versions if the object properties are changed, then we need to update
only Webelement identification code (i.e. Class-1)
-it will
Increase Readability of the script
-it will
reduces duplication of code
-it is easy
for maintainability
There are 2
types of approaches in POM framework
i. using By class
ii. **using PageFactory annotation
@FindBy
i.
Using By class:
By- is a static class provided in WD to assign webelement
locator values
Syntax:
By obj= By.locatorName(Locator value);
Exp:
Create script to check login functionality in mercury tours
web application using POM framework with help of By class
Procedure:
Step1:
create 2 packages
package-1:
"object.repository"
package-2:
"test.cases"
Step 2:
i.
create
non-executable class in "object.repository" package with
name as "MtHomePg"
ii.
assign
webelement identification locator values to variables
syntax: By obj= By.locatorName("Locator
value");
iii.
create
individual methods/functions to return each webelement
identification value
syntax:
public WebElement
methodName(WebDriver driver){
return
(driver.findElement(obj));
}
Script:
package object.repository;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class MtHomePg {
//to assign
locator values
By
userid=By.name("userName");
By
pwd=By.name("password");
By signin=
By.name("login");
public WebElement
uidObj(WebDriver driver){
return(driver.findElement(userid));
}
public WebElement
pwdObj(WebDriver driver){
return(driver.findElement(pwd));
}
public WebElement
signinObj(WebDriver driver){
return(driver.findElement(signin));
}
}
Step 3: create class in "test.cases" package and
write script to initialize
browser and to perform
login validation
package test.cases;
public class LoginValidation extends MtHomePg{
public static void
main(String[] args) throws InterruptedException {
WebDriver
driver= new FirefoxDriver();
driver.get("http://newtours.demoaut.com");
driver.manage().window().maximize();
//to
perform login operation
LoginValidation
lv= new LoginValidation();
lv.uidObj(driver).sendKeys("mercury");
lv.pwdObj(driver).sendKeys("mercury");
lv.signinObj(driver).click();
Thread.sleep(3000);
String
pgTitle= driver.getTitle();
if
(pgTitle.contains("Find a Flight")){
System.out.println("Successful
login operation");
}
else{
System.out.println("Unsuccessful
login operation");
}
}
}
---------------------------------------------------------------------------------
POM framework using PageFactory annotation @FindBy
==================================================
Exp:
create script to validate login functionality in
http://rediffmail.com
application using POM Framework with PageFactory annotation
Procedure:
Step1:
create 2 packages
package-1:
"object.repository"
package-2:
"test.cases"
Step 2:
create 2 non-executable classes in
"object.repository" package
class-1: RediffHomePg
Class-2: RediffLoginPg
Step 3:
assign home page webelement locator value to the object
using @FindBy annotation in "RediffHomePg" class
syntax:
@FindBy(Locator="Locator
value")
WebElement obj;
Step 4:
create method/function to return obj from
"RediffHomePg" class
syntax:
public WebElement
methodname(WebDriver driver){
return(obj);
}
Script in "RediffHomePg" class
----------------------------------------
public class RediffHomePg {
//Assign locator
value
@FindBy(linkText="Sign
in")
WebElement signin;
//to return obj
public WebElement
signinObj(WebDriver driver){
return(signin);
}
}
Step 5: assign Login page webelement locator values to the
objects
using @FindBy annotation in "RediffLoginPg" class
and create
method/functions to return each obj
class
script in "RediffLoginPg" class
--------------------------------
public class RediffLoginPg {
//Assign locator
value
@FindBy(name="login")
WebElement
emailId;
//Assign
locator value
@FindBy(name="passwd")
WebElement
pwd;
//Assign
locator value
@FindBy(name="proceed")
WebElement
go;
//to
return obj
public
WebElement emailObj(WebDriver driver){
return(emailId);
}
public
WebElement pwdObj(WebDriver driver){
return(pwd);
}
public
WebElement goObj(WebDriver driver){
return(go);
}
}
Step 6: create class in "test.cases" package to
validate login functionality
public class RediffLoginValidation {
public static void
main(String[] args) throws InterruptedException {
WebDriver
driver= new FirefoxDriver();
driver.get("http://rediffmail.com");
driver.manage().window().maximize();
//to
initialize objects from "object.repository" package classes
RediffHomePg
RHP= PageFactory.initElements(driver,
RediffHomePg.class);
RediffLoginPg
RLP= PageFactory.initElements(driver,
RediffLoginPg.class);
RHP.signinObj(driver).click();
RLP.emailObj(driver).sendKeys("SampleUserID");
RLP.pwdObj(driver).sendKeys("Password");
RLP.goObj(driver).click();
Thread.sleep(3000);
String
pgTitle= driver.getTitle();
if (pgTitle.contains("Inbox")){
System.out.println("Successful
login operation");
}
else{
System.out.println("Unsuccessful
login operation");
}
}
}
