5.13. My test requires that I use information printed to System.out or System.err to determine whether a test passed or failed. When I run my test in the harness, I can't seem to find these output streams.

Currently, information sent to System.out or System.err is only available after the test has finished running.

Note that this question indicates that the test itself can not determine whether it passed or failed (i.e. it needs human intervention). Thus, the test uses the manual option. The suggestions provided for the applet action may apply.
