Testing code is a common software development practice. Developers validate pieces of their code in an automated fashion to ensure it is working as expected. The new age of infrastructure development adopts this best practice to manage and maintain infrastructure code. Because of the fast pace development of Cloud Service Providers, infrastructure code rots quickly. The same code used to deploy an EC2 instance has a good chance of not working in 6 months if not kept up to date. Writing tests for Terraform code validates modules are always working as expected. It also provides faster feedback allowing quick changes to modules with confidence that they won't break the infrastructure using them in production. Terratest is an open-source Golang library used for testing Terraform and is quickly rising in popularity.
