Marked test expectations: https://trac.webkit.org/changeset/282274/webkit

Comment 3 ayumi_kojima 2021-09-13 11:30:43 PDT

I was able to reproduce the failure on BigSur using run-webkit-tests --iterations 100 --exit-after-n-failures 1 --force imported/w3c/web-platform-tests/webrtc/no-media-call.html.

The failure seems to have started at https://trac.webkit.org/changeset/279461/webkit

Also, looking at the history, recently the test has started consistently failing at around https://trac.webkit.org/changeset/282281/webkit

Test is no longer flaky according to bots after moving to standardised ice connection state callback.
