+// Test that each property defined in the Animation interface behaves as
+// expected with regards to whether or not it produces style change events.
+//
+// There are two types of tests:
+//
+// PlayAnimationTest
+//
+// For properties that are able to cause the Animation to start affecting
+// the target CSS property.
+//
+// This function takes either:
+//
+// (a) A function that simply "plays" that passed-in Animation (i.e. makes
+// it start affecting the target CSS property.
+//
+// (b) An object with the following format:
+//
+// {
+// setup: elem => { /* return Animation */ },
+// test: animation => { /* play |animation| */ },
+// shouldFlush: boolean /* optional, defaults to false */
+// }
+//
+// If the latter form is used, the setup function should return an Animation
+// that does NOT (yet) have an in-effect AnimationEffect that affects the
+// 'opacity' property. Otherwise, the transition we use to detect if a style
+// change event has occurred will never have a chance to be triggered (since
+// the animated style will clobber both before-change and after-change
+// style).
+//
+// Examples of valid animations:
+//
+// - An animation that is idle, or finished but without a fill mode.
+// - An animation with an effect that that does not affect opacity.
+//
+// UsePropertyTest
+//
+// For properties that cannot cause the Animation to start affecting the
+// target CSS property.
+//
+// The shape of the parameter to the UsePropertyTest is identical to the
+// PlayAnimationTest. The only difference is that the function (or 'test'
+// function of the object format is used) does not need to play the
+// animation, but simply needs to get/set the property under test.
