In their own words
Terratest
Terratest is an open-source Go library for writing automated tests for infrastructure code. Its helpers cover Terraform, OpenTofu, Terragrunt, Packer, Helm, Docker, and Kubernetes, as well as AWS, Azure, and GCP APIs. Tests can run infrastructure tools, deploy real resources, validate the resulting environment, and remove resources afterward. Validation can use HTTP requests, API calls, SSH connections, and shell commands. The documentation covers unit, integration, and end-to-end tests, along with parallelism, retries, error handling, and static analysis. Terratest runs locally and supports configuration-compliance checks, provisioning tests, deployed checks, and policy as code. The project is free under the Apache 2.0 License. The quick start requires Go 1.26 or later and OpenTofu or Terraform for its examples. The documentation recommends cleaning up after tests because they may create resources in real environments. General questions and issue reports go through GitHub Discussions and Issues; Gruntwork offers commercial support to companies using Terratest in production. The v1 line receives security fixes only while v2 is in development.
Test Kitchen
Test Kitchen is a free test harness for running infrastructure code in isolation on one or more platforms. Its workflow uses create, converge, setup, verify, and destroy commands to provision environments and test infrastructure code. Documented drivers cover Amazon EC2, Apache CloudStack, DigitalOcean, Docker through Dokken, Google Cloud Platform, Hetzner Cloud, Vagrant, Azure, Hyper-V, OpenStack, and VMware products. Which drivers are available depends on the driver gems installed in the Ruby environment. Provisioning options include Chef Infra, Cinc Client, Habitat, PowerShell DSC, and shell scripts; listed verification integrations include Cinc Auditor, Chef InSpec, and Serverspec. Community plugins add Ansible, Puppet, and Salt provisioners. Installation is available through RubyGems, system packages, or Cinc Workstation, but Test Kitchen itself does not bundle Cinc or Chef tooling. Requirements include a 64-bit operating system and enabled CPU virtualization. The project uses Apache License 2.0 and points users to Chef Community Slack for community assistance. The documentation notes known issues and no current maintainer for kitchen-docker, recommending kitchen-dokken instead.
