The Logic of Verification
Software testing is sometimes described as “verification and validation”—or, according to Wikipedia, “the process of checking that a software system meets specifications and that it fulfills its intended purpose.” Yet, renowned tester and teacher Michael Bolton argues, if we examine the concept and logic of verification, we quickly recognize that there are serious limitations to what can and cannot be checked and verified. This is not to say that checking is a bad thing—on the contrary; checking can be very valuable. Still, it’s important for testers and their clients to recognize the fundamental limitations of checking and to address those limitations in our testing strategies. Join Michael Bolton as he outlines the logic of verification, ways in which we might be vulnerable to false premises and misleading conclusions about it, and how we can address those problems by embedding verification in a larger system of testing, experimentation, and critical thinking.
