Developing cloud infrastructure applies the common software development practice of automated testing in order to ensure resources are being configured correctly and staying within the project's requirements. The increasing pace of cloud providers like Google Cloud Platform is a major reason to include these types of tests in your infrastructure development process. The process of configuring a resource today may not be the same as it was six months ago, and in most cases, automated tests are the only way to identify these updates. Another benefit of implementing testing is to ensure that future updates to your resources don't affect your overall infrastructure.

Terratest, is an open-source Golang testing library that enables you to set up tests for your Terraform resources and modules. Terratest can provide peace of mind as your infrastructure grows and can safeguard your infrastructure from many breaking updates.

In this lab, you write a test using the Terratest library that validates a Google Cloud Platform module configuration.
