I think I finally have the answer to my question,

When I wrote the regression tests,
I set each test up to be independent—each test got its own unique test data in the various “databases” we were using
(we weren't really using a database,
but custom binary data files based off a periodic database dump)
and in theory,
we could have run the tests in random order.
during my last year there,
I almost added that feature to the regression test,
but by then,
I was so burned out with The Process™ that I just never bothered.
It's a shame that,
because I think it would have been an interesting form of test to perform.
