aws-cdk-local VS terratest

Absolutely - CDK under the covers generates CloudFormation templates, which deploy natively on LocalStack. Certainly a great use case for local dev&test - especially if you want quick feedback cycles, ability to destroy the stack immediately, etc.

There's also a "cdklocal" command line which should make it fairly easy to get started with local CDK development: https://github.com/localstack/aws-cdk-local

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
