Sachin has just
published a draft whitepaper on database unit testing using Team Edition for
Database Professionals.
The whitepaper includes details steps on creating your first unit test;
automatic test generation; the standard test conditions available; and even
delves briefly into the C#/VB.Net code used by the testing framework.
I highly recommend users of Database Professionals ([story:datadude]) read
this whitepaper.
You can
download the draft directly. Make sure you
give feedback about the draft as well!
