Hi Kermit,
Ah. Try not to do that next time.
It's way too easy to be convinced that some test is working by just
copying the output of the code and looking for reasonable output. But
it's much more useful to write out the complete test case without
preconceptions, without the aid of the code you're trying to test. This
works because:
* You can't cheat yourself. *grin*
* Writing out the test cases first can help in writing the
real function.
Those test cases act as documentation that other people can look at.
They're a form of specification --- a requirement --- that allows others
to understand the intent of the function.
