Sounds a little too high-level for a unit test; I would probably use
FitNesse for something that high-level.

// do something that sets should_be_unity to 1.0
// in process 0, and 1.1 in process 1.

I would write two unit tests for these cases: one that checks each
scenario where should_be_unity is set to different values.

I would assume that MPI (or any other high-level
multiprocess/multithreaded framework) works as advertised and that I
don't need to test MPI.  I would write tests around my stuff and not
MPI.  This may require that you create a way to fake out MPI in your
unit test, which is no big deal.
