Part of my role at work is managing a fleet of robots, servers, and other infrastructure responsible for running our business. Due to the nature of our business, we run within customer warehouses.

Being a one man operation, one of my main concerns is keeping all the systems stable and proper working conditions. I am not the only developer touching our puppet code, but I’m the one responsible for the system(s).

As I embarked on the journey to add reliability to our infrastructure, something very clear came up: there’s a lot of information about testing puppet, but most of it is fractured, out of date, or hard to understand. See this slideshow from 2016 about the state of testing puppet.

I’m writing this post up to act as a handbook of sorts for testing puppet, as well as a ‘repository’ for testing puppet.
