> The [code for the jenkins junit
> plugin|https://github.com/jenkinsci/junit-plugin/blob/master/src/main/java/hudson/tasks/junit/CaseResult.java#L190]
> indicates stdout/stderr logs should be truncated to 1MiB for failing runs,
> and just 1 KiB for passing runs. However _all_ Beam tests seem to be
> truncated to 1 KiB, not just passing runs. This can make it very difficult to
> debug flaky tests, since they are challenging to reproduce locally, and
> nearly all the relevant information from the failures is removed.
