Yeah...  I mean the sort of test files one would incorporate in a CPAN tgz.

Here are the options:
   - write tests after you write the code
   - write tests *before* you write the code
       (supposedly the smart way to do things)
   - write (embed?) the tests into the code?!

It's the third I wondered about, though really I could use soem
