We have a third party application that we've layered our own asp.net app on top of and the vendor periodically changes some functions around when new releases come out. In particular a function was recently moved from one package to another. They also sometimes change the parameters for a given function that we rely on. Our developer is looking for a way to do some rudimentary unit testing to ensure we know when something has changed. The unit tests are being written in C#. So far we've been thinking of looking at all_source to check to see if a function is still in a particular package but we've yet to come up with a good way to check to see if the parameters have changed. Anyone got any suggestions while I continue my search? David -- //www.freelists.org/webpage/oracle-l
