How to implement page object and Page factory?
“Factory class can be used to make using Page Objects simpler and easier”. We use Page Factory pattern to initialize web elements which are defined in Page Objects.

You also can put the PageFactory.initElements (); into the constructor and create just an HomePage object instead of calling the PageFactory method. Important: If you call initElements () all elements will be initialized, not later if you use them. How to organize this? I do the following: Each page has a PageObject, that represent these.
