SQL Server unit testing

I've heard that unit testing is useful for application development, but the new thing to me was that there are unit tests for database data, too.

Henrik Ekelund has written a T-SQL Unit test framework for your SQL Server databases. In the unit testing spirit, this utility is available in open-source format at SourceForge.

I still have to convince myself of the usefulness of unit testing for database data, but nonetheless, it's good to know that something is available if you or I get interested in it.
