Bug 194779 – [ Mac WK1 ] REGRESSION (r239145) Layout Test http/wpt/mediarecorder/MediaRecorder-dataavailable.html is flaky text diff failure

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Shawn Roberts]

The following layout test is flaky on Mac WK1

http/wpt/mediarecorder/MediaRecorder-dataavailable.html

Probable cause:

Test has had several fix attempts. Continues to be a flaky failure or time out on Mac WK1. Also showing on Mac WK2 as a flaky timeout, but unable to reproduce that locally.
Has had text expectations changed for iOS

Reproducible with:

run-webkit-tests t241662 http/wpt/mediarecorder/MediaRecorder-dataavailable.html --iterations 500 -f -1 --no-retry
