I guess that would be nice to have documented, but it's not a use case
I've ever had.  Tests are usually grouped in separate files, so you'd
usually have (as in Emacs) "make foo-tests" or whatever in your
Makefiles.

The Emacs manuals usually document what's currently in Emacs, so it's a
bit odd to be talking about Emacs 24.1 here, isn't it?  So perhaps that
paragraph should just be removed?
