provider-test-patterns

To write acceptance tests for a Terraform provider, use structured patterns covering basic, update, disappears, validation, and regression scenarios. These patterns integrate terraform-plugin-testing and statecheck to validate plan and state artifacts effectively.

Testing ephemeral resources in Terraform providers requires patterns that reference external data without persisting it to plan or state artifacts. Following these best practices ensures your automated tests remain thorough and maintainable.

Statecheck and plancheck assertions work in provider testing by validating state and plan outputs during acceptance tests. They provide structured assertion methods for setup and teardown to verify code quality and resource configuration.

Yes, terraform-plugin-testing is required to use these provider test patterns. The structured testing approach relies on this framework alongside statecheck to execute automated acceptance tests and validate state artifacts.

A regression test pattern for Terraform provider development is a structured acceptance test scenario designed to prevent previous bugs from reoccurring. It ensures provider code quality by validating behavior across basic and update scenarios.
