We've used the Perl testing framework (Test::Harness, eg: 1..1\nok 1) in the main parrot test suite. It's working well for Perl and a Parrot version of it might be nice idea...
Anything that emits the Test::Harness protocol is fine. Anything that understands the Test::Harness protocol is fine. Just support the protocol and everyone's happy.
(I think Parrot is capable of interpreting the protocol right now.)
