What is the best way to automate Terraform testing ?

Layer it: `terraform test` for units, Terratest for integration/E2E, GitHub Actions to orchestrate. Units on PRs, full on main.

How do Terratest and terraform test differ?

Native tests mock logic, no infra. Terratest deploys real AWS, verifies outputs and connectivity — essential for cloud truth.

Is Terraform testing worth the setup time?

Yes — catches AWS-specific bugs early, scales teams, cuts costs long-term. Start small, one module.
