Take a look at test/pt_testcase.rb in ParseTree... It contains a large  
tree of tests including input and expected output. ParseTree uses this  
to test forward in the process. ruby2ruby uses this to go backwards.  
ruby2c extend the tree and then test off of that. It is pretty easy to  
extend for whatever you're doing.
