Ian Kelly called the System Under Test, SUT, the System Under Specification, SUS, at his session “Testing++ – Working with Spock and Geb” on Java Developer Day in Krakow.
System under upecification feels quit nice in the context of Behaviour Driven Development, BDD, where you define what the system should do and not how it should be done. I usually talk about system under test but I think I will change that. Or at least mix what I use. I want to emphasise that a test should be more of a specification than a verification. The word specification also emphasises the order in which things should be done. You usually specify what you want first. You don’t specify afterwards what you got.
Creating a specification after you delivered the software is documenting what actually was delivered and nothing else.
