Testing modules/policies

1. I understand that if a module is manually tested (by calling it and
feeding a pcap), its log entries will be saved on the same directory
said module was called from. But, what if the module is also supposed
to mail out? Would it be able to do the deed?

2. Is there a verbose option (I am thinking on the -v[v[v]] in
ansible/ssh) when you call

zeek -r pcap policy

I do not mean the -d option, as it seems to behave like gdb.

One option I use is zeek -r pcap misc/dump-events my-test-policy.zeek. See: https://docs.zeek.org/en/current/scripts/policy/misc/dump-events.zeek.html
