5. Run in CI
Local pre-commits are super useful but they’re even better in CI. With Terrateam you get all of these tests out of the box. No configuration required.
Native Terraform checks and trusted third-party tools run directly from the Terrateam GitHub Action to make sure your code is formatted properly, validated, and secure.
