chart-testing

Identifies which Helm charts have been modified against a target branch, enabling targeted testing only on changed charts, as highlighted in the README for pull request validation.

Integrates with Yamllint and Yamale to validate chart structure, syntax, and schema compliance, providing thorough checks beyond basic Helm linting.

Supports configuration via CLI flags, environment variables, and multiple config file formats (YAML, JSON, TOML), with clear precedence rules, as detailed in the README's configuration section.

Handles authentication for private chart repositories and OCI registries through extra Helm arguments, making it suitable for enterprise environments with secure chart sources.
