How do I run Terraform unit tests?

`terraform init && terraform test` in your module dir. Needs 1.6+. Write .tftest.hcl with plan assertions.

What's the best tool for Terraform integration testing?

Terratest. Go tests deploy real infra, assert outputs/HTTP, defer destroy. Beats kitchen-terraform on speed.

How much does Terraform E2E testing cost on AWS?

$0.05-0.20 per run for micro instances. Limit to post-merge or cron to stay under $20/month.
