1. What is POM ? Advantages of POM?

Page Object Model (POM) is a design principle to manage the test cases and page objects separately.Framework types like data-driven, behavior-driven, keyword-driven, etc. can be designed with the page object model. 

The main advantage of Page Object Model is that if the UI changes for any page, it don’t require us to change any tests, we just need to change only the code within the page objects.

improves code readability - Allows us to separate operations and flows in the UI from Verification

Re-usability of code - a locator or function can be reused in the tests.Eliminate 

redundancy – no duplicity of functions or locators.

2. What is Page Factory?

Page Factory is enhancement of POM. Page factory provide the facility to locate and initialize Web Elements of an page without using findElement( ) or findElements( ) method of selenium

Page factory provides annotations like @FindBy, @FindAll, which locate the web element and return the WebElement instance for the same

While automating the test cases, we create the object of these Page Classes and interact with web elements by calling the methods of these classes

Strategy Design pattern

6. What are the Challenges faced while Working with Selenium Automation?

Generally an automation engineer face is maintaining the code.
If your application is frequently changing html elements of the page and some new components are being added and so on, this may affect your code especially locators.
