How does testing contribute to the failure of a project? Todd Gardner chats with Carl and Richard at NDC Oslo about his experiences with failing projects and testing. More than just the usual case that a lack of testing led to unreliable software, Todd also talks about how testing the market is important too - what if you build software nobody wants? The focus has to be on relevant tests, because every test represents an overhead of computing and maintenance. This ultimately comes back to understanding the value proposition of your software: What does your software do that is valuable, and how do you assure that value with testing?
