This is something i was agonizing about too when I was reviewing this code last week.

Do we:
 - stick to having namespaces everywhere, because That's How It's Always Been - and suffer with long test names?
 - drop namespaces everywhere for our test projects, because they're just noise around our proper test names?

I'm tending towards the latter, but let's see what @half-ogre and @haacked think (oh, and anyone else reading this)
