[Israel.pm] Testing a library

[Shmuel Fomberg]

Hello There.

I had in work a library that actually was a thin wrapper around
XMLRPC::Lite.
I have replaced it with a new library that I wrote, that suppose to do
the same.
My question is: how do I test it? I need to know that the two libraries
are completely parallel. 
Does XMLRPC::Lite return error if I send the wrong number of parameters?
The wrong type?
I have in the new lib a call table, that is a hash where the key is the
function name, and the values are parameters list. (as in/out) 

Any Idea?

Shmuel.
