Supplied test set...

Hello, I am dimas from Indonesia.

I wonder how to test my model based on supplied test set at RapidMiner. I usually do such activity on WEKA. ::)
My purpose is at least to find out performance of my model when it's applied on testing set. such that, I can choose the best model having best accuracy on training set and test set. ;D

I apreciate all replies from you all. if you're so kind to share the XML process, of course it will be great! ;)

Thank You
