Testing in Infrastructure as Code and why Terraform may not be the best option

• example-iac-test

  9 4 0.0 Groovy

  Terraform and AWS CDK test examples

  

We are not testing all the cases here, just a single integration test, because we can finally write unit tests! The code looks like this https://github.com/devopsbox-io/example-iac-test/blob/master/src/test/groovy/io/devopsbox/infrastructure/test/s3/S3ConstructPropsTest.groovy

• aws-cdk

  263 11,158 9.9 TypeScript

  The AWS Cloud Development Kit is a framework for defining cloud infrastructure in code

  

Finally, we can write the code in a real programming language of our choice and create unit tests. Is it perfect? Certainly not. Our integration tests run in a different process, so there are some drawbacks. There is support for running in the same process in Pulumi (https://github.com/pulumi/pulumi/issues/3901) but not in AWS CDK yet (https://github.com/aws/aws-cdk/issues/601). We can also improve our “miniframework” and run tests using a chosen IAM role - we do that in DevOpsBox already, but it is not included here for the sake of simplicity.

• terratest

  46 7,336 8.4 Go

  Terratest is a Go library that makes it easier to write automated tests for your infrastructure code.

  

You can’t use Terratest assertions with LocalStack and there is an open pull request https://github.com/gruntwork-io/terratest/pull/495 solving this issue. Of course, you could write your own assertions and we will do it later in a different language, so let’s skip this now and move on.

• terraform-cdk

  104 4,720 9.9 TypeScript

  Define infrastructure resources using programming constructs and provision them using HashiCorp Terraform

  

I hope that the terraform-cdk project (https://github.com/hashicorp/terraform-cdk) will be usable soon and maintained in the future. Then, we will be able to have a cake and eat it too!

• aws-cdk-local

  Thin wrapper script for using the AWS CDK CLI with LocalStack
