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.

I'm not arguing with you, your clarifying comment was fine. I'm arguing with the person who replied to you.
