My own view is that `requires` was is meant
for a *user* interested in that particular test,

whereas

`depends` is something a *developer*, who
presumably understands the concepts of build
dependencies trees, would specify as he is
developing the test

so trying to correlate these two keywords is
not required.

But happy to change these if that is what the
consensus is.

P.S.  I'll note that the literal answer to Jed's
original question of RTFM does work and has been
there for over a year:
