Open sourcing Terratest: a swiss army knife for testing infrastructure code by Yevgeniy Brikman

Infrastructure as code (IaC) tools such as Terraform, Packer, and Docker offer a number of advantages: you can automate your entire provisioning and deployment process, you can store the state of your infrastructure in code (instead of a sysadmin’s head), you can use version control to track the history of how your infrastructure has changed, and so on. But there’s a catch: maintaining a large codebase of infrastructure code is hard. Most IaC tools are immature, modern architectures are complicated, and seemingly minor changes to infrastructure code sometimes cause severe bugs, such as wiping out a server, a database, or even an entire data center. Here’s the hard truth: most teams are terrified of making changes to their infrastructure code. The goal of Terratest is to change that. Terratest is a Go library that makes it easier to write automated tests for your infrastructure code. I won’t claim that writing....
