Terraform testing pyramid: unit, integration, end-to-end layers with tools and costs

  • Layer unit (native, free), integration (Terratest, minutes), E2E (full stack) for bulletproof IaC. 𝕏
  • GitHub Actions tiers runs: PR units, main integration, nightly E2E—cost-smart. 𝕏
  • Terraform 1.6 native tests mark IaC's JUnit moment; expect widespread adoption. 𝕏
