How to test changes to buildbot?

[Moxinilian]

I am trying to add a reporter to the buildbot configuration so a comment tagging the authors is created on a commit for which a build has failed. However, this is my first time touching buildbot configs and while I am slowly starting to understand how buildbot works, I have no idea how to actually test my code.

Is this even possible? If not, how does one create changes? @gkistanova maybe you would know?
