Intended use of the Unit Testing built in to CI

[eluser]Frank V[/eluser]
In most framework unit testing implementations, you have a set of a tests and you execute those tests from a single [console] command. The tests run and a result is given. That result varies but generally it includes pass / fail.

CI's unit testing framework appears different and I have noticed an extensive collection of random tack-on-projects to either enhance or replace the CI unit testing framework.

My question is this: What is the intended work flow or use of the unit testing framework built in to CI?

I read the documentation; I get it. It's a simple class. But where does one utilize the class?

For example, do all the tests go in to a single "test" controller? Or do the tests get intermingled in to each controller? Then there is the question of the models and custom helpers...

Thanks for the guidance!
