Helm unit tests


Simon Fontana Oscarsson
 

Hi,

Are there any good options for writing unit tests for Helm charts? My use case is that I want to test that, when setting a parameter, the correct changes are applied to the chart.

I've looked a bit at the helm-unittest project (https://github.com/lrills/helm-unittest) and it looks good enough. Unfortunately it is no longer maintained, last commit was almost a year ago and many issues are left unanswered. For example it doesn't have Helm v3 support (yes, there is a PR but I don't want to apply hotfixes and maintain the project myself).
Are there any other good projects with healthy community support for Helm chart unit tests?

As one of the maintainers I'm biased, but try out Conftest
https://github.com/instrumenta/conftest

We have a Helm plugin which makes this easier too

Thank you Gareth. At a first glance it looks good and I will surely try it out.
