I'd strongly prefer the tests to be deterministic and not do random 
different actions each time they're run. That way, any failures are much 
easier to track down. Writing randomly generated data is fine, but not 
random access patterns or sets of operations.

Although I suppose you could implement two sets of tests; one that does 
a static set of operations driven by a table in the board config file, 
and one that does a more randomized set of operations controlled by 
limits set by a table in the board config file.
