Scaling Terraform Test in GitLab

Thu, 28 May 2026 00:00:00 +0000

As Terraform module counts grow, testing stops being a “nice to have” and becomes the thing that either keeps your platform honest or quietly falls apart. The hard part is rarely writing a single terraform test file — it is making that pattern repeatable across every resource module, every composite module, and every merge request without copying CI logic into a dozen repos or hundreds of repos.

I put together a small public GitLab group, terraform-test, to walk through one way to scale this: resource-specific modules, composite modules that compose them into a solution, and a shared CI template that runs terraform test the same way everywhere.
