Testability is integral to almost everything we testers do. It’s one of those things that seems intuitive and easy to understand until you really stop to think about it. We’re going to crack open the world of testability, uncover its different dimensions and their relationships. Participants will build a rich model of testability and use it to question themselves, their environment and of course a test product. We’ll look at using this model to build testability heuristics, identify lack of testability and to adapt their testing to suit. This workshop is for testers but any one in software development will benefit from this workshop since the degree of testability affects everyone involved.
