Learning Helm Testing

This repository is designed to help me learn how testing works in Helm charts. It provides a simple example of end-to-end (E2E) testing for a Helm chart deployed to a local Kubernetes environment using Kind.

Task Overview

The Taskfile in this repository automates the following steps to test the Helm chart:

1. Deletes the Kind cluster (if it exists).
2. Creates a new Kind cluster.
3. Deploys the Helm chart to the newly created Kind cluster.
4. Runs end-to-end tests on the deployed Helm chart:
   • One test will pass.
   • One test will fail.

These tests are specifically designed to demonstrate how Helm tests are structured and executed in a Kubernetes environment.

Running the Test

To execute the task and run the end-to-end test, simply run the following command:

task e2e-test

This command will:

• Clean up any existing Kind cluster,
• Create a new Kind cluster,
• Deploy the Helm chart to the cluster,
• Run the tests, and
• Display the results (one test will pass, and one will fail).

Prerequisites

Before running the tests, make sure you have the following tools installed:

• Kind (for creating a local Kubernetes cluster)
• Task CLI (for running tasks)

Purpose of the Repository

The primary goal of this repository is to explore and learn about Helm chart testing, including how to:

• Write test hooks for Helm,
• Use helm test to execute tests against deployed applications, and
• Understand how Helm interacts with Kubernetes resources during testing.
