 In this module testing is performed with [terratest](https://github.com/gruntwork-io/terratest) and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a [GO environment](https://golang.org/doc/install) in your system.
 
 You need to run the following command in the testing folder:
