testing -- one piece to abstract-out of tests

[Fred T. Hamster]

the thing about running repeatedly, and choosing a random test to run?

that needs to be implemented as a class in unit tests.

like, choose_test_workflow.

all tests must be registered some kind of function it can call, then it can randomize
the order?

it needs a mode to run through the tests sequentially, not random.

it needs a selector of how many run throughs to do.

this would take a bunch of crap out of the tests and make them a lot nicer, but still
retain our ability to hammer the classes under test.
