TestWebKitAPI.GPUProcess.CrashWhilePlayingVideo TestWebKitAPI.GPUProcess.CrashWhilePlayingAudioViaCreateMediaElementSource TestWebKitAPI.MediaSessionTest.RemoteCommands Are consistently failing APIs in MacOS. Failures started after changes were landed in r272445 and a new test: TestWebKitAPI.MediaSessionTest.RemoteCommands was added.

It looks like https://trac.webkit.org/changeset/272456 disabled the MediaSessionTest API tests, but we're still seeing the GPUProcess tests fail on the bots.

This should be fixed by r272547.

Can we confirm if this got fixed?

Comment 5 2021-02-09 14:35:06 PST

TestWebKitAPI.GPUProcess.CrashWhilePlayingAudioViaCreateMediaElementSource appears to be consistently passing now. TestWebKitAPI.GPUProcess.CrashWhilePlayingVideo appears to be a flaky failure, but that may have started shortly before r272445 landed.

I confirmed the TestWebKitAPI.GPUProcess.CrashWhilePlayingVideo flakiness started before. This bug can be resolved.
