Verbose Output in Tests

Hi everyone,

As author and maintainer of a Perl Module I'm interested in using the great test matrix infrastructure of CPAN-Testers.
Unfortunately I see that many test fail in the remote systems
http://matrix.cpantesters.org/?dist=Process-SubProcess;os=linux;perl=5.32.1;reports=1
while they never failed in any of my automated or manual tests. So, I actually can't reproduce it and also are unable to tell what the issue could be from the summary output

Please, how can I see or activate the verbose testing?

Best Regards,
Bodolfo
