@ilhamv, created this Pr just to make sure the unit tests fail. I will be updating the unit tests to pass in here aswell.

@ilhamv I have updated all of the existing unit tests to now pass, it looks like there were just minor interface changes to some of the methods. I did not expand the unit tests, as I think that belongs in a separate PR.
