# Unit-test Helm charts with YAML assertions before deployment templates reach clusters with helm-unittest

Render a Helm chart locally and assert on the generated Kubernetes objects before a broken template makes it to a cluster.

## Prerequisites

Helm, the helm-unittest plugin or container image, a Helm chart repository, and chart test files written in YAML.

## Installation

Choose whichever fits your setup:

1. Copy this skill folder into your local skills directory.
2. Clone the repo and symlink or copy the skill into your agent workspace.
3. Add the repo as a git submodule if you manage shared skills centrally.
4. Install it through your internal provisioning or packaging workflow.
5. Download the folder directly from GitHub and place it in your skills collection.

Install command or upstream instructions:

```
Install the helm-unittest plugin or use the published container image, add chart test files under the chart test path, then run helm unittest against the target chart locally or in CI before deployment.
```
