  1. What drives development if not verification? There is a Dijkstra quote about having logically proven that some code is correct, one cannot verify that it works until it is run. The most useful test tool I've used in my career was an in-house record compare program called C12RC that could compare two complicated sequential inputs in amazing ways: late 70s at the Chicago electric utility where I learned programming. In the system and program utility context where I've spent most of my time it is more often the case that you find a test rather than write one. For a Java platform on a device there are conformance test suites for every api. But those tests are just the baseline. You also need to test real applications. But this work was more about optimisation, extending apis, and refactoring out the confusion that manifests itself as fragility or resistance to change than about generating new functionality.
