Helm Chart Testing Example using Terratest

This repository contains the example code from the blog post "Automated Testing for Kubernetes and Helm Charts using Terratest".

The directory structure represents a typical helm chart repository containing various charts in the charts directory and the tests for those charts under the test directory. The test folder contains the corresponding terratest code for testing each of the charts in the charts directory.

Quickstart

Prerequisites

To run the tests, you will need a working go install. See here for instructions on installing go on to your platform. Make sure to use a version >=1.13.

Kubernetes cluster

Some of the tests (specifically the integration tests) require a Kubernetes cluster to run. The easiest way to get a Kuberenetes cluster is to use minikube, which is a local single node installation of Kubernetes. Follow the instructions in the link to install and setup minikube.

Once minikube is installed, you will also need to install the helm client run the tests based on helm install. Follow the official guide for instructions on installing helm.

Running the tests

To run the tests, first change directory to the test folder of this repository, and then use go test to run the tests:

cd test
go test -v .
