We should make a test for this, I wrote #1335 to address the issues with Zabbix Agent2's default ootb include structure (that requires 2 include statements to fully work), but I completely missed it with the unit tests..

OK I like what you did here, I would just make one ask. Given what @AlexPykavy did in #1366 that handles both a string and a list, if you can do the same thing here so we can be consistent.

I've updated my PR to support this.

I have no experience writing tests, so i cant help out on this.
