I should probably mention that I volunteered as owner of the Animations  
testsuite a while back (since nobody else spoke up) [1], and that since  
then, I have created about 150 tests (not submitted quite yet). Those are  
all automated via testharness.js (some using setTimeout, some using the  
animation events, some neither), and can also be visually/manually  
inspected for a more thorough check (they don't have reference animations,  

There seems to be no owner for Transitions yet, by the way [2].

Opera doesn't support requestAnimationFrame currently. I suppose this  
makes me biased as well, but I think it would be unfortunate if the W3C  
testsuites were to depend on proprietary features (as far as I know,  
current implementations are all prefixed and the spec is at FPWD).
