Description Ryan Haddad 2018-04-10 10:02:46 PDT
The following layout test is flaky on all ports.

imported/w3c/web-platform-tests/workers/name-property.html

Probable cause:

This started with the WPT re-sync in https://trac.webkit.org/changeset/230445/webkit

Marked test as flaky in https://trac.webkit.org/r230483
Comment 2 Simon Pieters (:zcorpan) 2018-06-21 05:14:12 PDT
The test was fixed in https://github.com/web-platform-tests/wpt/pull/11186

Can TestExpectations be updated?

I don't think anyone has merged the fix into our repo, as the test is still frequently failing according to https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fworkers%2Fname-property.html

Has the test been imported now? Can it be imported and enabled?

It would be *nice* with automatic two-way sync for wpt<->WebKit. :-)

The flakiness may actually be down to bug 259409.
