It silences HUnit's output, but will tell you what happens when there is a failure- which I think is what you want. There are a few available output formatters if you don't like the default output, or you can write your own output formatter.

BDD is really a red herring. Instead of using function names to name tests you can use strings, which are inherently more descriptive. In chell you already have `assertions "numbers"`, in hspec it would be `it "numbers"`. The preferred style it to remove `test test_Numbers and the test_Numbers definition` which are redundant in this case, and instead place that inline where you define the suite, although that is optional.
So I really can't tell any difference betwee "BDD"  and "pass/fail assertions". You still just use assertions in hspec.

I have, but it's not quite what I'm looking for:

- I don't want to silence HUnit's output, I just don't want anything
to show on the console when a test *passes*. Showing output on a
failure is good.

- I'm not interested in BDD. Not to say it's not useful, but it
doesn't match my style of testing (which uses mostly pass/fail
assertions and properties).
