Those bastards.  Have you tried asking?  (I will if you won't.)

The cool thing about the view testing is that it pushes me to identify
what data each actually view needs and giving the view (or partial)
that data through instance variables.  Otherwise, I tend to get lazy
and access data more directly than I probably should.

Would be also handy if the view tests could incorporate
assert_valid_markup or assert_valid_asset somehow.
