If I understand then yes you can. Itís a kinda convoluted, expensive, and hacky way to do what I think youíre asking. Plus youíll probably have to, at some point, munge the IO layers so the TAP output isnít visible. FWIW, I rely on it frequently in testing.
ok some_test(), "Some test passed"
or diag "BUNCH O'DEBUG INFO or $@ or whatever...";
There is a Test::* space module that purports to run tests without output but I canít remember the name because when I tried to use it a few months ago it did not work as advertised so I wouldnít be recommending it even if I could remember it. :P
