## プロジェクトの歴史と使われ方

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.

### プロジェクトの歴史

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.

### 採用の歴史

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.

### 使われ方

`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`.

### パッケージ好きにとっての重要性

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.

### タイムライン

- 2017-11: Helm chart-testing repository created.
- 2018-11: v2.0.0 released after the refactor from bash library to Go.
- 2025-10: Latest upstream GitHub release metadata lists v3.14.0.

### Related projects

- Helm is the chart ecosystem that `ct` validates.
- chart-releaser is a sibling Helm tool for publishing charts after testing.
- yamllint, Yamale, kubectl, Git, and Helm are documented prerequisites in the official README.
