Updated test expectation from pass/timeout to pass/failure because I don't see any timeouts anymore.
Comment 3 ayumi_kojima 2021-10-15 11:28:20 PDT
The flaky failure seems to be rarely happening on iOS 15 (I only see one time so far).
Comment 4 ayumi_kojima 2021-10-15 14:05:45 PDT
I was not able to reproduce the failure locally on iOS 15 simulator using run-webkit-tests --force --debug --iterations 50 --exit-after-n-failures 1 http/wpt/service-workers/skipFetchEvent.https.html --ios-simulator.

Closing the bug.
