"That sounds a lot like "if my code is bad, I'll find out when it breaks in production, so why test?""

Oh no defintely not, no I mean you test and build your ansible and cluster stuff in Development / Acceptance. We create our monitoring checks there as well. And when all that is done and "green": we go to production.

BTW. Testing your cluster is something you do in dev/acc before you go to prod. And Ansible / monitoring already shows you problems in those pre-production stages.

What added benefit is there for Goss in that scenario?
