Metamorphic Testing
Confession: I read the ACM Magazine. This makes me a dweeb even in programming circles. One of the things I found in it is “Metamorphic Testing”. I’ve never heard of it, and nobody I knew heard about it either. But the academic literature was shockingly impressive: many incredibly successful case studies in wildly different fields. So why haven’t we heard of it before? There’s only one article anywhere targeted at people outside academia.
