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.
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.
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 deploy Tiller to run the tests based on helm install. To deploy
Tiller, you will first need to install the helm client. Follow the official
guide for instructions on installing helm.
Once helm is installed, you can setup Tiller on minikube using helm init:
helm init --wait
To verify Tiller deployed correctly, use helm version. If the deploy was successful, you should see both the client
and server versions:
$ helm version
Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
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 .
