I would still prefer to have MediaSessionTest a friend of MediaSession if that
means we can avoid adding a FooForTest() method.

I think you could move MediaSessionTest class outside of the anonymous
namespace. Then declare this class as friend of MediaSession in the MediaSession
class. You should then be able to call new
MediaSession(adoptPtr(webMediaSession)) here. No need to use FRIEND_* macros.
