+**NOTE:** Be sure to merge the latest changes from "upstream" before making a pull request!## Running Terraform Tests
+
+We use [Atmos](https://atmos.tools) to streamline how Terraform tests are run. It centralizes configuration and wraps common test workflows with easy-to-use commands.
+
+All tests are located in the [`test/`](test) folder.
+
+Under the hood, tests are powered by Terratest together with our internal [Test Helpers](https://github.com/cloudposse/test-helpers) library, providing robust infrastructure validation.
+
+Setup dependencies:
+- Install Atmos ([installation guide](https://atmos.tools/install/))
+- Install Go [1.24+ or newer](https://go.dev/doc/install)
+- Install Terraform or OpenTofu
+
+To run tests:
+
+- Run all tests:  
+  ```sh
+  atmos test run
+  ```
+- Clean up test artifacts:  
+  ```sh
+  atmos test clean
+  ```
+- Explore additional test options:  
+  ```sh
+  atmos test --help
+  ```
+The configuration for test commands is centrally managed. To review what's being imported, see the [`atmos.yaml`](https://raw.githubusercontent.com/cloudposse/.github/refs/heads/main/.github/atmos/terraform-module.yaml) file.
+
+Learn more about our [automated testing in our documentation](https://docs.cloudposse.com/community/contribute/automated-testing/) or implementing [custom commands](https://atmos.tools/core-concepts/custom-commands/) with atmos.
