See Subject.
Not doing so would be reasonable, as there is no check phase anyway,
however, packages using guile-build-system can define their own check
phase that should respect #:tests?, but currently they can't, as
#:tests? is always unset and hence (when tests? ...) is never run.
(I would give an example, but it's not in Guix yet.)
Patch to be written.
