imported/w3c/web-platform-tests/html/dom/idlharness.worker.html Is flaky failing on iOS Debug & macOS Debug. History: https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fhtml%2Fdom%2Fidlharness.worker.html Result page: https://build.webkit.org/results/Apple-BigSur-Debug-WK2-Tests/r283308%20(4012)/results.html Diff: Attached. Catalina wk1 Debug has been failing for a while (Bug 206503)

I was not able to reproduce the failure locally on BigSur AS using run-webki-tests --debug imported/w3c/web-platform-tests/html/dom/idlharness.worker.html --iterations 50 --no-timeout --exit-after-n-failures 1 -f. The test timed out instead. With --no-timeout flag, it hanged.
Marked test expectations https://trac.webkit.org/changeset/284639/webkit
It looks like the diff is different now than before on both iOS and macOS: --- /Volumes/Data/worker/ios-simulator-15-debug-tests-wk2/build/layout-test-results/imported/w3c/web-platform-tests/html/dom/idlharness.worker-expected.txt +++ /Volumes/Data/worker/ios-simulator-15-debug-tests-wk2/build/layout-test-results/imported/w3c/web-platform-tests/html/dom/idlharness.worker-actual.txt @@ -1,4 +1,5 @@ Blocked access to external URL http://invalid/ +CONSOLE MESSAGE: WebSocket connection to 'ws://invalid/' failed: A server with the specified hostname could not be found.

It looks like the pass/fail expectations were overwriting "DumpJSConsoleLogInStdErr". Updated the expectations https://trac.webkit.org/changeset/284727/webkit
It seems the test passes on macOS now. Removed the expectation https://trac.webkit.org/changeset/284903/webkit
I was not able to reproduce the failure using run-webkit-tests --force --ios-simulator --debug --iterations 500 --exit-after-n-failures 1 imported/w3c/web-platform-tests/html/dom/idlharness.worker.html
The test started as flaky/pre-existing failure on macOS-Catalina-Debug-WK1-Tests-EWS. Marked test expectations again for mac-wk1 debug: https://trac.webkit.org/changeset/284931/webkit
It is a flaky timeout, the test is just slow to run. We should probably just mark it as slow or skip it in Debug.
