terraform-switcher VS terratest

‍TFSwitch is a CLI tool that allows easy switching between different Terraform versions, simplifying workflows in environments where multiple Terraform versions are used.

tfswitch might help with particular issue of terraform versioning:

Even then some versions of terraform providers are not compatible with M1 macs. Docker would help with that probably, but so can: https://github.com/kreuzwerker/m1-terraform-provider-helper

Perhaps these sort of issues support the benefits of per-module docker images?

My approach is to change the version in the version.tf file, install the new version using tfswitch (https://tfswitch.warrensbox.com/) and execute a plan. If infrastructure matches the configuration I will asume there are no breaking changes...

Also, an excellent tool can help with fast switching between different Terraform versions while you’re experimenting — tfswitch.

It was easy. I didn't use terraform-version files like you, but there are similar ways to automatically switch versions. https://github.com/warrensbox/terraform-switcher

Terraform Switcher - yet another project essentially doing the same written in go;

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.

I think I found it. This is the one right? https://github.com/gruntwork-io/terratest/

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.

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.

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.

Once there is a CI pipeline for delivering infra changes you can add static code analysis tools (checkov) and even start testing changes (terratest)

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