This is a library for creating your own custom elements in java selenium.
It provides a way to easily create your own custom HTML elements adding also adding support for those elements inside the html iframe tag (#document).
That's easy, just make a class that extends the CustomElement
class.
If you want to define an element that is inside the Iframe, you need to extend the DocumentElement
class.
Also, there are some cool functions on the DocumentUtils
class that you might want to check out.
