I’ve been a big advocate of testing for applications, databases, data warehouses, BI and analytics for a while now. Not just any testing, but real tests that help you truly verify the state of your code, applications and data. I like Test Driven Development, but really any approach that focuses on automated, repeatable tests that verify meaningful functionality I find hugely beneficial. And almost no one I’ve ever talked to about this topic has disagreed with me. (There was that one guy, but he was a FoxPro developer, so…) But there’s often a point where the conversation goes sideways.
