that raises one of the interesting questions in test-driven development: 
if a test fails and you check and still think that you've implemented 
what the spec text asks you to implement, how do you reconcile? 
special-casing just for tests probably isn't the way to go, so how 
exactly did you tweak the code (or your interpretation of the spec 
resulting in code) to satisfy the test?

i am really interested, because i'll be implementing it as well and i am 
pretty sure that i'll run into the exact same issue.

thanks and cheers,

dret.
