Terratest

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.

package test

import (
 "context"
 "fmt"
 "testing"
 "time"

 "github.com/Azure/azure-sdk-for-go/storage"
 "github.com/gruntwork-io/terratest/modules/azure"
 "github.com/gruntwork-io/terratest/modules/random"
 "github.com/gruntwork-io/terratest/modules/testing"
)

func TestAzureStorageAccount(t *testing.T) {
 t.Parallel()

 // Set the Azure subscription ID and resource group where the Storage Account will be created
 uniqueID := random.UniqueId()
 subscriptionID := "YOUR_AZURE_SUBSCRIPTION_ID"
 resourceGroupName := fmt.Sprintf("test-rg-%s", uniqueID)

 // Create the resource group
 azure.CreateResourceGroup(t, resourceGroupName, "uksouth")

 // Set the Storage Account name and create the account
 accountName := fmt.Sprintf("teststorage%s", uniqueID)
 accountType := storage.StandardZRS
 location := "uksouth"
 account := azure.CreateStorageAccount(t, subscriptionID, resourceGroupName, accountName, accountType, location)

 // Create a container in the Storage Account
 ctx := context.Background()
 client, err := storage.NewBasicClient(accountName, azure.GenerateAccountKey(t, accountName))
 if err != nil {
  t.Fatalf("Failed to create Storage Account client: %v", err)
 }
 service := client.GetBlobService()
 containerName := fmt.Sprintf("testcontainer%s", uniqueID)
 if _, err := service.CreateContainer(ctx, containerName, nil); err != nil {
  t.Fatalf("Failed to create container: %v", err)
 }

 // Check if the container exists
 testing.WaitForTerraform(ctx, terraformOptions, nil)

 // Cleanup resources
 defer azure.DeleteResourceGroup(t, resourceGroupName)
}

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.
