I'm really not sure how useful these tests are going to be and would 
question the long term maintenance costs of keeping them up-to-date.

I could see perhaps verifying that when there are multiple alternatives 
that the correct one is selected or somesuch, but these tests really 
don't seem to be covering anything particularly useful.
