| michael@0 | 19 | /* Test for Bug 628888 - Animations in external document sometimes don't run |
| michael@0 | 20 | * |
| michael@0 | 21 | * This bug concerns a condition where an external document is loaded after the |
| michael@0 | 22 | * page show event is dispatched, leaving the external document paused. |
| michael@0 | 23 | * |
| michael@0 | 24 | * To reproduce the bug we attach an external document with animation after the |
| michael@0 | 25 | * page show event has fired. |
| michael@0 | 26 | * |
| michael@0 | 27 | * However, it is difficult to test if the animation is playing or not since we |
| michael@0 | 28 | * don't receive events from animations running in an external document. |
| michael@0 | 29 | * |
| michael@0 | 30 | * Our approach is to simply render the result to a canvas (which requires |
| michael@0 | 31 | * elevated privileges and that is why we are using a MochiTest rather |
| michael@0 | 32 | * than a reftest) and poll one of the pixels to see if it changes colour. |
| michael@0 | 33 | * |
| michael@0 | 34 | * This should mean the test succeeds quickly but fails slowly. |
