Re: Testability of Animation from interactions Issue 18

>Would that make the Animation SC easier to test and the proposal something
you can live with?

- Significant animation: Animation which continues for more than 1 second,
and affects more than 1/3 of the view of the webpage.

- I would say 2 seconds threshold, so any animation less than 2 seconds
passes, allowing most CSS transitions, which are an important design
paradigm.
- For the field, perhaps saying something like it has >500 CSS PX   again
that is fairly arbitrary... but at least measurable.

- Significant animation: Animation which continues for more than 2 seconds,
and the movement occupies more than 500 CSS pixels on the webpage
