Bug 247775 – REGRESSION (256161@main): [ macOS Debug ] TestWebKitAPI.GPUProcess.OnlyLaunchesGPUProcessWhenNecessaryMediaFeatureDetection is a consistent failure

• Component: New Bugs
• Status: RESOLVED FIXED

[Karl Rackler]

Description:
TestWebKitAPI.GPUProcess.OnlyLaunchesGPUProcessWhenNecessaryMediaFeatureDetection

The first failure I saw on the dashboard was at 256161@main.  This test consistently fails for BigSur, Monterey, and Ventura Debug bots.  

Reproduction steps:
I can reproduce this on 256164@main but cannot reproduce it on 256158@main or earlier.  Looking at the commits, https://commits.webkit.org/compare/256158@main...256164@main , 256161@main modifies the GPUProcess and appears to be the commit that started the consistent failures.

Command: 
run-api-tests --debug TestWebKitAPI.GPUProcess.OnlyLaunchesGPUProcessWhenNecessaryMediaFeatureDetection

History:
https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.GPUProcess.OnlyLaunchesGPUProcessWhenNecessaryMediaFeatureDetection&limit=5000

test result:
Failed
