Conftest is a testing tool that validates structured configuration data using the Rego query language from Open Policy Agent.
Conftest solves the problem of enforcing policies and standards across infrastructure and application configuration files. Rather than writing custom validation scripts for each configuration format, it provides a unified testing framework where policies are expressed in Rego, a declarative language designed for policy evaluation. This approach allows teams to define assertions once and apply them consistently across Kubernetes manifests, Terraform code, Tekton pipelines, Serverless configurations, and other structured data formats.
Teams should adopt Conftest when they need to enforce organizational standards, security policies, or best practices across configuration files at scale. It suits projects where multiple developers or teams manage infrastructure-as-code and need consistent validation before deployment. The tool works with any configuration format that can be parsed into structured data, making it broadly applicable across different technology stacks and infrastructure tools.
The project shows sustained development with regular commits addressing bug fixes, feature enhancements, and dependency updates. Pull requests receive timely review and feedback from maintainers. The project maintains active engagement with its community through a dedicated Slack channel and welcomes external contributions through documented development and contribution guidelines. Issue tracking reflects ongoing refinement of the tool's capabilities and responsiveness to user needs.
