Hmm, so no explanation as it is assumed interested parties understand the subject.. you can see my point I hope.
I don't see your point. Assuming that interested parties understand it is fine. If you don't understand, find out. Of course, it would be better to have the phrase "unit test framework" somewhere so that someone stumbling upon the repository would be better able to find out what the GUI is for if they don't know (or even just recognise the phrase immediately), but not having it is not a big deal either.
I've read most of the Zandstra book but rarely use the principles set out therein.
Likewise, you assume that our dear visitors have a clue as to the "Zandstra book"
Even a verbatim Google search on 'languageUnit pattern' returns zilch.
Okay, maybe I should have written "fooUnit pattern" instead, but then you might ask what is foo
But yes, why didn't you search for "phpUnit" instead of "languageUnit pattern"?
