Top Terraform Tools to Know in 2024
Terratest is a Go library that provides tools and patterns for testing infrastructure, with first-class support for Terraform, Packer, Docker, Kubernetes, and more. It's used to write automated tests for your infrastructure code.

Saw a not-so-good thing in my pipeline. How do we fix it?
I think I found it. This is the one right? https://github.com/gruntwork-io/terratest/
-
terracove - open-source to instantly test the health of your terraform/terragrunt repository
What it does in parallel is basically init/plan/show using terratest on every subdirectory on your repository tree or provided paths. The output is either a JSON summary or a custom made Junit XML test file you can ingest into your tests reader. It took it around 8 minutes to map the entirety of our bloated repository.

Trunk Based Development: Confused about how to test code before pushing to main? How does the deploy process work for many environments?
You could deploy to a separate account (usually dev first), you can use terratest, you could try something like LocalStack. I dare say there’s other methods.
-
terratest for infrastructure
Was wondering if anyone has tried https://github.com/gruntwork-io/terratest to test their infrastructure. I like it because I can write golang tests! Thats a big plus for me.
- Is there a testing framework for Kubernetes and AWS resources?
-
How long have you guys actually had the title “platform engineer”? What other titles did you have before that, if any?
Once there is a CI pipeline for delivering infra changes you can add static code analysis tools (checkov) and even start testing changes (terratest)

Appreciation for terraform
Another plus is to add tests into your workflow, just by adding a run step with terratest

Self-service infrastructure as code
Our first attempt was to introduce other engineering teams to Terraform - the Platform team was already using it extensively with Terragrunt, and using Atlantis to automate plan and apply operations in a Git flow to ensure infrastructure was consistent. We'd written modules, with documentation, and an engineer would simply need to raise a PR to use the module and provide the right values, and Atlantis (once the PR was approved by Platform) would go ahead and set it up for them.
