Use Cases or Problem Statement

A new terraform-plugin-testing Go module has been released. New testing functionality will only land in terraform-plugin-testing and this should allow most providers to stop depending directly on terraform-plugin-sdk.

Proposal

Follow the migration guide: https://developer.hashicorp.com/terraform/plugin/testing/migrating
