Looks pretty good to me.  Only three things come to mind: 
compareOne() still needs to be implemented; testing floating-point
color values for exact equality (rather than for 0.5LSB tolerance or
something like it) might be risky; and you might want to use
GLUtils::useScreenCoords() rather than setting up your own projection
and viewport parameters (so that the test checks the setup people are
most likely to use, because it's recommended in the Red Book).

Nice to have the test, though; scissoring is one of those things that
are often overlooked.
