Description Bri Harris 2023-02-23 11:40:22 PST

TestWebKitAPI.WKWebViewCloseAllMediaPresentations.VideoFullscreen

is a flaky timeout on iOS 16 only. 


HISTORY:

https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.WKWebViewCloseAllMediaPresentations.VideoFullscreen


TIMEOUT ERROR:

TestWebKitAPI.WKWebViewCloseAllMediaPresentations.VideoFullscreen
        2023-02-23 10:13:10.597 TestWebKitAPI[38829:25202454] Encountered error: Error Domain=WKErrorDomain Code=5 "JavaScript execution returned a result of an unsupported type" UserInfo={NSLocalizedDescription=JavaScript execution returned a result of an unsupported type} while evaluating script: window.internals.setMockVideoPresentationModeEnabled(true)

Comment 1 Bri Harris 2023-02-23 11:47:52 PST

I was able to reproduce this time out on a release build as follows:

run-api-tests --ios-simulator --root WebKitBuild/Release-iphonesimulator TestWebKitAPI.WKWebViewCloseAllMediaPresentations.VideoFullscreen

Comment 3 Ryan Haddad 2023-02-27 11:36:53 PST

This timeout appears to be consistent on iPhone simulator release queues. https://commits.webkit.org/260575@main is in the regression range, and seems like it could be related.

Comment 4 Ryan Haddad 2023-03-07 10:46:01 PST

This test is no longer timing out as of 261100@main, but I don't see an obvious change to credit with fixing it.
