Terraform test framework (1.6+) - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the Terraform test framework introduced in version 1.6+?

It allows you to write automated tests for your Terraform configurations to verify that your infrastructure code works as expected before deployment.

intermediate

Which language is used to write tests in the Terraform test framework?

Tests are written in HCL (HashiCorp Configuration Language) using run and check blocks.

intermediate

What is the role of the 'run' block in Terraform tests?

It defines the configuration for running Terraform commands in tests, including the source directory of Terraform code, variables, and environment settings.

advanced

How does the Terraform test framework help with infrastructure state management during tests?

It automatically initializes, applies, and destroys Terraform configurations in isolated test environments to avoid affecting real infrastructure.

beginner

Name one best practice when writing tests using the Terraform test framework.

Keep tests small and focused, clean up resources after tests, and use variables to make tests reusable and maintainable.

What command does the Terraform test framework typically run to prepare infrastructure during tests?

A terraform validate

B terraform plan

C terraform destroy

D terraform apply

The framework runs 'terraform apply' to create or update infrastructure as part of the test setup.

Which programming language do you use to write Terraform tests with the test framework?

A HCL

B JavaScript

C Python

D Ruby

Terraform tests are written in HCL using run and check blocks.

What is the purpose of a destroy run block in tests?

A To initialize Terraform

B To clean up resources after tests

C To validate configuration syntax

D To plan infrastructure changes

A destroy run block removes resources created during tests to avoid leftover infrastructure.

Which of these is NOT a benefit of using the Terraform test framework?

A Manual deployment of resources

B Automated verification of infrastructure code

C Isolated test environments

D Early detection of configuration errors

The framework automates deployment, so manual deployment is not a benefit.

What does a 'run' block NOT typically include?

A Path to Terraform code

B Terraform variables

C Test case assertions

D Cloud provider credentials

run blocks configure Terraform command execution; assertions are written separately in check blocks.

Explain how the Terraform test framework manages infrastructure lifecycle during tests.

Think about setup, verification, and cleanup steps.

Describe best practices for writing maintainable tests using the Terraform test framework.

Consider test design and resource management.
