Cinc Auditor vs Terratest

Cinc Auditor is a free distribution of Chef InSpec for compliance and audit workflows on Linux, macOS, and Windows. Its profiles are fully compatible with upstream counterparts, and its tools work with InSpec; an InSpec wrapper redirects to Cinc Auditor so existing automation can keep working. Installation options include scripts, Bundler, RubyGems, and plain packages. Cinc also publishes a Docker Hub image as a drop-in replacement for chef/inspec. It can run InSpec-compatible profiles in CI or against containers, with GitLab CI and GitHub Actions named as examples. Auditor is included in Cinc Workstation. Cinc says its binaries use the Apache 2.0 license without additional EULAs or licensing. The project does not provide formal warranties or support, and it does not currently offer repositories for standard package managers such as yum or apt. The free plan costs nothing. Cinc recommends contacting Progress for warranty or support needs.

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.
