> The Surefire upgrade to 3.3+ added enableOutErrElements which defaults to
> true and includes system-out and system-err in the xml artifacts. This
> significantly increases their size: ~45KB to ~1MB in many cases. In my test
> environment, that leads to
> {code}
> Recording test results
> ERROR: Step ‘Publish JUnit test result report’ aborted due to exception:
> java.lang.OutOfMemoryError: Java heap space
> {code}
> Capturing stdout seems useful when doing ad-hoc testing or smaller test runs.
> I'd propose adding a profile to set enableOutErrElements=false for CI
> environments where that extra output can cause problems.
