What is the black belt testing?

Within the Royce Gracie network, what is the black belt testing?  Royce decided that promoting to the black belt needed to be different because it was a huge thing.  So he decided to team up with colleagues of his to create a very formal testing procedure.  They invite the brown belts to be tested in front of resisting black belt opponents.  It’s a very rigorous test.
