I'm glad to see people starting to write about modern development techniques for relational databases.  I suspect that over then next two or three years we're going to see major changes with respect to how databases are developed and evolved.   We're clearly moving away from the serial approach favored by many data professionals to the evolutionary approach favored by application developers.

If you're interested in reading more about database regression testing, I suspect that you'll find http://www.agiledata.org/essays/databaseTesting.html to be an interesting read.
