Here is how I think of it, Jeff.

Usability is a dimension of design. I like the construct of useful, usable
and desirable which you can think of as three dimensions that a good design
requires.

Each of these dimensions has associated with it various tool and techniques.

Usability testing is a technique that can be used to assess (some aspects
of) usability. Other techniques like persona development also contribute to
usability. 

For me, this makes it all pretty simple. A good design must be usable. But
usability is not the only characteristic of a good design.
