Let's also include TypeScript testing for new modules, as we can not test the business logic of scripts with Terraform-only tests.

left a few suggestions. I think we need to have both simultaneously.

TypeScript tests can be skipped if the module does not run any scripts.

Ahh I okay I'm seeing the whole picture better now. I'll commit your other change and give it one more look over before it's merged

Can we update the script in package.json to run all tests when someone run bun test

Doesn't the package.json currently do this already?

  "name": "registry",
  "scripts": {
    "fmt": "bun x prettier --write . && terraform fmt -recursive -diff",
    "fmt:ci": "bun x prettier --check . && terraform fmt -check -recursive -diff",
    "terraform-validate": "./scripts/terraform_validate.sh",
    "test": "./scripts/terraform_test_all.sh",
    "update-version": "./update-version.sh"
  },

I think we just need to omit the examples from the terraform_test_all.sh script. I will do this tomorrow morning and get this finished up.
