If it's a test app meant to investigate the behavior, that's fine, but
then there's no reason to put it in the test suite.

Just use it to figure out the behavior, and then write a proper test
that checks for that behavior using ok() and the like. At that point you
don't need traces, because the test is supposed to run unattended and
detect failures on its own, without requiring anybody to look at a
trace.
