Composite action that installs the desired version of Helm through azure/setup-helm, the latest version of the helm-unittest plugin, and then executes chart unit tests for the specified charts or, if none are specified, for every chart found in the repository.

The github-token input is necessary only when installing the latest version of Helm, to overcome GitHub API rate limits. If not given, refer to the azure/setup-helm README for more information.

unittest-version can be set to an empty string, or to latest. This allows a github variable to be used to "pin" a version, or to use latest since you cannot set a variable to an empty string.

The install-mode input controls how helm-unittest should be installed. These are the available installation modes:

This composite action can be used in any workflow that requires Helm unit tests. For every chart it finds, it will run helm dependency update to ensure chart dependencies are present.
