t2d2

Terraform Test Driven Development

Why?

Testing Terraform code currently requires knowledge of a new set of tools which make crossing the bridge from Application Development to Infrastructure quite difficult.

How?

t2d2 helps bridge this gap by allowing you write your IaC tests with familiar JavaScript testing frameworks like Jest, Mocha, UVU etc.,.

Getting Started

1. Create a starter jest project. You can explore the sample test in resources.ts

mkdir my-infra-project
cd my-infra-project
npm init @t2d2/jest-starter

2. Customize the terraform workspace path in your tests' beforeAll hook, if required.

...

profile = await t2d2.init({
  profileName: 'resources',
  workspaceDir: './tf', # <--
})

...

3. Start your TDD cycles.
