In the Terratest example below, a function is created to test the creation of an Azure storage account in a resource group, and a container in the storage account, then verifies that the storage account and container exist. The resources are then cleaned up after the test is complete.

Unit Testing
Unit testing involves testing individual modules or resources in isolation to ensure that they work as expected. This can again be done using tools like Terratest or using Terraform’s built-in testing functionality.
