HashiTalks 2024: Mastering Terraform Testing, a layered approach to testing complex infrastructure
This blog post is the writeup of my talk at HashiTalks 2024 on the Terraform test framework. I discuss a layered approach to testing where we begin by using declarative validation in our Terraform modules and follow this up with successively more advanced tests. I will also discuss the need for policy-as-code because not everything makes sense as tests, some things should be policies.

The Pragmatic Programmer’s Guide to Deliberate Infrastructure-as-Code

The Pragmatic Programmer teaches us to not program by coincidence, instead we should program deliberately. What does this mean in the context of infrastructure-as-code? What does ClickOps, abstractions, and implicit actions have to do with it all? In this post I vent a bit of thoughts related to this.

Take your testing to the cloud

Take your testing to the cloud
I have written a lot about the new Terraform testing framework, but there is one piece of the puzzle that I have written almost nothing about: Terraform Cloud. In this post I will go through how to publish a module to a private Terraform Cloud registry and enable testing for the module. I will also show you the new test generation using AI.

Test permutations with Terraform and GitHub Actions

Test permutations with Terraform and GitHub Actions
I continue my exploration of the new Terraform testing framework with this post where I demonstrate how to run permutations of a given test using GitHub Actions. Specifically I’ll dive into an example where our module depend on a different module, and we are required to support a given number of recent versions of this module.
