-// httpServer is NOT tested, for the following reasons:
-// * It depends on a `net.Listener`, which is not trivial to mock.
-// * It does very little besides passing an httpHandlers along to an http.Server
-// and managing cleanup.
-// * It isn't likely to be changed often.
-// * If it were to break it would be very apparent in subsequent testing stages.
