You and the OP are referring to different things. Terraform the codebase has a test suite. Terraform the app does not have a test suite/runner as in a way to run tests against your Terraform files.
It doesn’t have a testing tool built in. No one legitimately understands the phrase “terraform doesn’t have a test suite” to mean anything except “there are no tests”. A runner and a suite are quite different.
I can understand the miscommunication in the first post, but I clarified in a direct comment to you what I meant. I was even comparing it to Terratest, which is not used for testing terraform core. At this point you're just being belligerent for the sake of being belligerent.
