Bug 175909 – REGRESSION (r220052): VideoControlsManager.VideoControlsManagerMultipleVideosSwitchControlledVideoWhenScrolling is a flaky API test

• Status: RESOLVED
• Resolution: FIXED
• Component: Media

[Matt Lewis]

The API test VideoControlsManager.VideoControlsManagerMultipleVideosSwitchControlledVideoWhenScrolling is a flaky timeout on macOS Sierra.

This test looks to have started to be flaky after r220052 like other tests from VideoControlsManager

Results:
https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK1%20%28Tests%29/builds/4087/steps/run-api-tests/logs/stdio
https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK2%20(Tests)/builds/3798

I was able to confirm the regression point locally by running all of the api tests on a debug build. I was unable to reproduce the timeout when just running the VideoControlsManager test alone.

Disabled the test for now in:

I'll fix the flakiness of these three tests in this bug:

VideoControlsManager.VideoControlsManagerMultipleVideosSwitchControlledVideoWhenScrolling
VideoControlsManager.VideoControlsManagerMultipleVideosScrollOnlyLargeVideoOutOfView
VideoControlsManager.VideoControlsManagerMultipleVideosScrollPlayingMutedVideoOutOfView

But it turns out VideoControlsManagerMultipleVideosSwitchControlledVideoWhenScrolling is also permanently failing for other reasons.  I'll file a separate bug on that after fixing the flakiness.
