Bug 278549 – [ macOS ] TestWebKitAPI.ResourceLoadStatistics.GrandfatherCallback is a flaky timeout (failure in EWS)

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Marta Darbinyan]

The following API tests are timing out intermittently both on Ventura and Sonoma. 
TestWebKitAPI.ResourceLoadStatistics.GrandfatherCallback
TestWebKitAPI.ResourceLoadStatistics.MigrateDataFromIncorrectCreateTableSchema

The test became flaky first on Sonoma both on Debug and Release and later on Ventura Release. It's also reproduced in EWS as pre-existing failure.

I can't reproduce a timeout on TestWebKitAPI.ResourceLoadStatistics.GrandfatherCallback with 1000 iterations. I'm going to unskip that test.

TestWebKitAPI.ResourceLoadStatistics.MigrateDataFromIncorrectCreateTableSchema has a separate issue, I'll fix that test in https://bugs.webkit.org/show_bug.cgi?id=308477
