The document is a presentation about testing Terraform configurations with Terratest. It introduces Terraform as infrastructure as code tool and Terratest as a Go library for testing Terraform configurations. The key points covered are: - Terraform allows building, changing and versioning infrastructure safely and efficiently through infrastructure as code - Terratest enables writing tests in Go to validate infrastructure deployed by Terraform configurations and orchestrate test stages - The demo will show setting up Terraform and Terratest environments and running a sample test

4. What is an Infrastructure?

5. WHAT is Terraform?
● Terraform is an infrastructure as code (IaC) tool that allows you to build, change and version infrastructure safely and efficiently.
● This includes low-level components such as compute instances, storage, and networking, as well as high-level components such
as DNS entries, SaaS features, etc.
● Terraform can manage both existing service providers and custom in-house solutions.
● For writing configuration in terraform we use HCL.
Key Components of Cloud Infrastructure
● Compute
○ EC2
● Network and Content Delivery
○ VPC
● Storage
○ S3 Bucket
● Security, Identity and Compliance
○ IAM

6. WHY Terraform?
● Terraform is a provisioning tool.
● It follows a declarative Infrastructure as a Code approach.
● It is the best fit for orchestrating cloud services and setup cloud infrastructure from scratch.

7. WHAT is Terratest
● Terratest is a Go library developed at Gruntwork, that makes it easier to write automated tests for our infrastructure code.
● It provides a variety of helper functions and patterns for common infrastructure testing tasks but here we will be discussing about
Testing Terraform code.
● It is used to perform end to end testing for our IaC.
○ E2E testing is typically a three-step process.
1. A configuration is applied to a test environment.
2. Code is run to verify the results.
3. The test environment is either reinitialized or taken down (such as deallocating a virtual machine).

8. Go Language
● Go is an open source programming language supported by Google.
● Built in concurrency and a robust library.
● Easy to learn and get started with.
Use Cases of Go

9. WHY Terratest?
● Deploy a Terraform configuration.
● Enables you to write a test using the Go language to validate what has been deployed.
● Orchestrate the tests into stages.
● Tear down the deployed infrastructure
