terraform-test

You can unit test Terraform modules without real cloud resources by using mock providers to run isolated tests, validating infrastructure logic and resource configurations locally before deployment.

To validate Terraform naming conventions and tags in a CI pipeline, define structured test scenarios with assertions that check resource properties and outputs, enabling rapid and repeatable compliance checks.

The best way to structure Terraform tests for plan and apply modes is to define predefined scenarios with specific assertions for each mode, allowing detailed output control and robust validation of infrastructure changes.

Yes, you can use mock providers for isolated Terraform testing to achieve fast, local validation of module logic and resource relationships without accessing or modifying actual cloud environments.

Yes, Terraform testing supports detailed output control designed for CI pipelines, providing structured test results and assertion outputs that facilitate robust, repeatable infrastructure validation.

Terraform tests for resource relationships fail when predefined assertions do not match the module's outputs or configurations, indicating that the infrastructure logic violates the expected validation rules or best practices.
