One of the things that testers in my classes on ATDD and Exploratory Testing struggle the most with is that programmers and testers appear to give up independence with this approach. My first reaction to this is often that I hear them asking to leave their testing silos in place, and start to convince them to collaborate more with the programmers. By hard I recently learned that the Helpful Model (“No matter how it looks, everyone is trying to be helpful.” Secrets of Consulting, page 101) and the Rule of Three Interpretations (“If I can’t think of at least three different interpretations of what I received, I haven’t thought enough about what it might mean.”, Quality Software Management Volume 2 First-order measurement, page 90) also applies to myself.
