💡 Hint

Common Mistakes

Using 'terraform apply' before initialization causes errors.

Confusing 'plan' with 'init' command.

Terraform must be initialized with terraform init to download providers and set up the working directory before testing.

💡 Hint

Common Mistakes

Using 'apply' instead of 'plan' when creating a plan file.

Forgetting to specify the output file with '-out'.

The terraform plan command creates an execution plan and saves it to a file for review or testing.

💡 Hint

Common Mistakes

Using 'terraform plan tfplan' instead of 'apply'.

Trying to initialize with 'init' when applying.

To apply a saved plan file, use terraform apply tfplan. Using 'plan' or 'init' here is incorrect.

4fill in blank

hard

Fill both blanks to write a Terraform test block that checks if a resource attribute equals a value.

Terraform

test "resource_attribute" {
  check "state_check" {
    assert {
      condition = [1] == [2]
    }
  }
}

Drag options to blanks, or click blank then click option'

Aresource.aws_instance.example.id

B"running"

C"stopped"

Dresource.aws_instance.example.state

Attempts:

💡 Hint

Common Mistakes

Using the instance ID instead of state for comparison.

Comparing to the wrong string value.

The test checks if the instance state equals "running" using the correct resource attribute.

5fill in blank

hard

Fill all three blanks to create a Terraform output that shows the public IP of an instance after integration testing.

Terraform

output "instance_ip" {
  value = [1].[2].[3]
}

Drag options to blanks, or click blank then click option'

Aaws_instance

Bexample

Cpublic_ip

Dprivate_ip

Attempts:

💡 Hint

Common Mistakes

Using 'private_ip' instead of 'public_ip'.

Mixing resource names or types.

The output accesses the public IP attribute of the example AWS instance resource.
