Oops, that's right, the REST API normally isn't exposed except to
localhost.  My bad.

My point is that no, you can't.  If you don't have real use cases, you
will write tests that don't matter, and you will fail to cover things
that some real use case depends on.  Often enough, those things can be
really basic, and embarrass both your programmer's pride and your
schedule.  Both strategies, a priori (here's my API definition, make
sure it works) and use-case-based (here's my use case, make sure the
API can implement it) are necessary.
