Note that because the current test framework simply decides if a test 
passes or fails based on the return code, it can be used to call any 
program which uses that convention.

So you could have a test that called an expected results comparison testing 
program, as long as that program reported pass/fail results via its return 
code.

One of the uses of that I've often thought of was to run execution timings.
