Bug 182176 – Layout Test imported/w3c/web-platform-tests/service-workers/service-worker/appcache-ordering-main.https.html is flaky

• Component: Service Workers
• Status: RESOLVED WONTFIX

[Matt Lewis]

The following layout test is a flaky timeout on High Sierra WK2

imported/w3c/web-platform-tests/service-workers/service-worker/appcache-ordering-main.https.html

Probable cause:

Currently goes back further that the flakiness dashboard as such, I'm unsure of a regression point for now

Flakiness Dashboard:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fservice-workers%2Fservice-worker%2Fappcache-ordering-main.https.html

Should be fixed by https://bugs.webkit.org/show_bug.cgi?id=183148.
I reactivated the test inadvertently in https://bugs.webkit.org/show_bug.cgi?id=183264 as it was passing locally with the above patch.

This test is still a flaky timeout. It seems to time out more frequently on High Sierra.

Skipped test again in https://trac.webkit.org/r229827

AppCache is now disabled and will be removed in bug 219391.
