@dotnet/dnceng BA is not matching the error, presumably because is not in the console log? It's in xharness-output\testResults.xml.

[jozkee]

Duplicate of #113836 but for a different test.

@jozkee this documentations says where Known Issues can look at error information: https://github.com/dotnet/arcade/blob/main/Documentation/Projects/Build%20Analysis/KnownIssues.md#how-the-matching-process-works-between-a-known-issue-and-a-buildtest-error

[jozkee]

@missymessa looks to me xharness-output\testResults.xml is a helix log. I also set "ExcludeConsoleLog": true, assuming that gives more range in case the 100 logs limit was being reached.

But looks like BA gave up on this issue.

[missymessa]

@jozkee I can open an issue to investigate this. Are you currently blocked on this?

[jozkee]

No, I'm not blocked on it, thanks.

[lewing]

@jozkee this is too broad of a pattern to be useful. It will catch any timeout even newly introduced ones.

[jozkee]

@lewing I just broadened it because I saw LoadLazyAssemblyBeforeItIsNeeded (#113836) existed and I got #113836 (comment) I suspected more tests would fail and wouldn't be great to have one issue per each failing test. Feel free to adjust it.

[lewing]

KnownBuildErrors that can easily hide new regressions are actively harmful by making what should be failing CI look green. It is always a balance but blanket matches against a timeout are generally too broad.
