Overview

Package `infratests` is intended to act as a testing harness that makes testing Terraform templates easy and efficient. The goal of this package is to minimize the boiler plate code required to effectively test terraform implementations.

The current implementation is focused only on unit tests but it will be expanded to harness integration tests as well.

- Run `terraform plan`
- Validate terraform plan file.
