After fighting with unit testing the UI in a Cocos2d-x app, I finally put together a fairly straightforward way to put the catch.hpp unit tests into an application so that I can run a fully automated set of Unit Tests against the UI portion of my application.
I put together a short video where a cocos2d-x project is created from scratch and the UI Unit Testing is implemented.
It is my goal to further simplify the integration of these UI unit tests.
I hope this helps someone.
