Project history and usage
Chart Testing is the Helm project CLI, `ct`, for linting and testing Helm charts, especially in pull-request and CI workflows where changed charts need to be detected and validated.
Project history
The Helm organization created the chart-testing repository in November 2017. Its README notes that v2.0.0 refactored the tool from a bash library to Go while keeping v1 parity, and GitHub release metadata shows v2.0.0 published in November 2018 and the current v3.14.0 release in October 2025.
Adoption history
Chart Testing spread with Helm chart repository CI. The README recommends the Quay Docker image because it bundles Helm, Git, yamllint, Yamale, and kubectl; it also documents binary releases and Homebrew installation, while the input facts list Homebrew, Nix, pacman, and zypper packaging.
How it is used
`ct` is used to list changed charts, lint charts, install charts, and run combined lint-and-install checks. Configuration is supplied by CLI flags, `CT_` environment variables, or config files, and default config lookup includes the current directory, `$HOME/.ct`, and `/etc/ct`.
Why package nerds care
Chart Testing is package infrastructure for packages-that-are-YAML: it gives Helm chart maintainers repeatable CI checks around chart metadata, dependency linting, schema validation, Kubernetes installation, and change detection. For chart repositories, it fills the role that language package ecosystems often get from their native test and lint commands.
