In Junit, failed tests have a failure tag that is read by Bamboo and displayed in the test summary as reason for failed test. See the attached screenshot:

There are instances where successful tests can have tags like the system-out. It will be nice to capture that as well and show in the summary. Here is an example

 <testcase classname="SultanTest" name="test" time="0.0">
    <system-out message="some test descriptions." type="" />
  </testcase>
