David Baron points out that a clever strategy is to use negative transition-delays to jump to arbitrary points in the transition so you don't have to wait -- Gecko uses this in test_transitions_per_property.html. Together, I think all these approaches should give us pretty good test coverage without any special APIs. (There are always the usual concerns about what error bars to use, though. I wish the specs would actually say, instead of requiring me to make something up.)
