I attended a little party on Monday night for VSTS influencer's.
I met some very nice people, who are very excited about their work. I had a short discussion about the new Visual Studio for DBA's. This sounds like a nice tool. One of the features I liked from a testing/deployment/promotion model point of view is being able to compare Data between versions of the Database.
When you are testing an application you must have control variables. So often this is not the case. Other industries are laughing at us over this. I remember reading an article in American Scientific written by an engineer who was slamming the software industry because we do not have standard process and controls in place like the engineering community. Anyway One of the most important parts of testing is to have a Database that you know the state of when executing tests. If you don't know what data is in your Database how can you be sure the test results are accurate.
It sounds to me like there will be tools to help in the coming version or Visual Studio for DBA's
