This tutorial on Selenium will help you understand what is Page Object Model (POM) and Page Factory? You will also understand why POM design pattern should be followed for creating your test case. The following topics will be covered in this session: 1. Why Use Page Object Model(POM)? 2. What Is Page Object Model? 3. What Is Page Factory? 4. Demo: Creating POM & Page Factory

Why Use Page Object Model?
A Web page has ‘x’ no. of elements, which are used in multiple test cases.
Now if the path/locator of any element changes, then what happens?
PROBLEM STATEMENT
A web page with ‘x’ elements
OH MY GOD !!
Do I have to change
the element locators
in entire test script?
Test Script
SOLUTION
Test
case
Element
locator

What Is Page Object Model?
Page Object Model is a design pattern to create an Object Repository for web UI elements.
Here, all the element locators used by the application will be stored in a class file separately from test case.
Test

Page
Class
Locators & test script stored separately
POM Design Pattern
• Element locators
• Methods performing operations on elements.
Page Class contains
• Actual test scenario
• Calls to methods in page class with arguments.
Test Case contains

What Is Page Factory?
POM Implementation
With
Page Factory
Without
Page Factory
• Uses By().
• No imports needed.
• No cache storage.
• Uses @FindBy().
• Import package: Page factory.
• Cache lookup is faster.
Page Factory is a built-in class in Selenium for maintaining object repository. (Import package: Page Factory)
With Page Factory, initElement() statement can be used for easily looking up elements in page class.
Page Factory allows storing of page elements in cache memory using @CacheLookup annotation.
1. Maintainability
2. Reusability
3. Flexibility
4. Optimized code
ADVANTAGES

WebDriver vs. IDE vs. RC
➢ Data Warehouse is like a relational database designed for analytical needs.
➢ It functions on the basis of OLAP (Online Analytical Processing).
➢ It is a central location where consolidated data from multiple locations (databases) are stored.
