On some of my test cases (that almost certainly fail anyway right now),  
I’m  
getting the following error message:

NameError: uninitialized constant  
Test::Unit::Assertions::AssertionMessage::PP

Has anyone else seen this one? They’re very straightforward test cases  
using assert\_equal. Google isn’t revealing it’s secrets to me, so I’m  
hoping someone here knows what to do for this message… Thanks in  
advance!

Never mind, putting require ‘pp’ at the top of the test case file fixed  
this. Weird, but ok.
