just wondering if anyone had some hints or code examples for wrapping umbraco features in interfaces for unit testing.. was looking at writing an xslt extension that would retrieve a couple of node's by ID's and compare their collections and return a random result..

i.e. someone passes in a node ID.. we get that node by ID and then find 5 other random nodes from it's same level that aren't it and then build an xml result and return..

so I'd need to wrap umbraco.library.GetXmlNodeByID() etc.
