the ALM Plugin should support/upload the JUnit <system-out> and <system-err> data used in the <testcase ...> </testcase>. The very useful data is available since several years but not used/handled by the QC.
The data should added in the QC to the "Test Lab", "Test Instance Details" "Attachments"
or to the "Run Details" "Comments" or "Attachments".
A suggestion only,
Some JUnit information available from https://stackoverflow.com/questions/4922867/what-is-the-junit-xml-format-specification-that-hudson-supports/4925847
