I think it's neither: it's perfectly fine to use the R error system to
signal being unable to establish function postconditions, but then the
tests shouldn't fail because of that (yes, including the \donttest{}
ones).
So, in my opinion, both stop() and the error message are okay, but the
example should wrap them in try() / tryCatch() and check the return
value correctly.
