Chart Tests

    A test in a helm chart lives under the directory and is a pod definition that specifies a container with a given command to run. The container should exit successfully (exit 0) for a test to be considered a success. The pod definition must contain one of the helm test hook annotations: helm.sh/hook: test-success or helm.sh/hook: test-failure.

    Example tests: - Validate that your configuration from the values.yaml file was properly injected. - Make sure your username and password work correctly - Make sure an incorrect username and password does not work - Assert that your services are up and correctly loadbalanced. - etc.

    In Helm, there are two test hooks: and test-failure

    test-success indicates that test pod should complete successfully. In other words, the containers in the pod should exit 0. test-failure is a way to assert that a test pod should not complete successfully. If the containers in the pod do not exit 0, that indicates success.

    In :

    1. $ helm install stable/wordpress

    • You can define as many tests as you would like in a single yaml file or spread across several yaml files in the templates/ directory
    • You are welcome to nest your test suite under a directory like <chart-name>/templates/tests/ for more isolation
