1613352 - Intermittent ERROR in workers/modules/shared-worker-options-credentials.html in WPT

Status: RESOLVED WORKSFORME

(Core :: DOM: Workers, defect, P3)

Description

[Philip Jägenstedt [:foolip]]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36

Steps to reproduce:

https://github.com/web-platform-tests/wpt/pull/21571 added a test workers/modules/shared-worker-options-credentials.html and it was run through stability testing as part of the CI setup.

Actual results:

The test was found to be flaky: https://github.com/web-platform-tests/wpt/pull/21571#issuecomment-582377852

Sometimes it's TIMEOUT and sometimes it's ERROR due to "SyntaxError: import declarations may only appear at top level of a module".

Expected results:

Consistent TIMEOUT. I can't see why the SyntaxError happens.

This bug appears to be part of the testing component. If incorrect, please set a more appropriate one.
Moreover, I cannot confirm it due to its high-level technicality. Need info me if I can help with manual testing.

Thank you for your contribution!

Thank you for making us aware of this intermittent failure on our infra; thankfully we seem to have addressed this in the interim (our searchfox page https://searchfox.org/mozilla-central/source/testing/web-platform/tests/workers/modules/shared-worker-options-credentials.html would tell us if there were recent intermittents or any expectations of failure).
