@Values() annotation on a unittest takes a range. Base that on a range 
that yields random values and Bob's your uncle.

That range may need to be a compile-time constant. If so, it will be a 
little awkward to create, and you can ping Atila about possibly creating 
a @ValuesFrom annotation that will take a method or lambda that yields a 
range of values.
