Cannot complete my final project testing

I am hoping someone can give me some of their time.

I am on my final project, Anonymous Message Board and I cannot get my chai testing to work.
I think it’s because I use references in my mongoose models as the chai tests don’t create database objects where ref is used.

Also my chai tests don’t return a response body, so I can’t do any asserts, etc.
I think this is because I use mongoose promises.

If you have the time my github is at:

Hi Sonnerz, did you ever find a solution for the response body issue?
