Question about Helm version used in unit tests

[lsolovey]

Hi @quintush,

first of all - thank you so much for maintaining this great plugin!

I have a question about actual version of the Helm engine used while running unit tests. You publish multiple Docker images for the same version of helm-unittest, e.g. the latest version 0.2.8 has images: https://hub.docker.com/r/quintush/helm-unittest/tags?page=1&name=0.2.8

• 3.7.1-0.2.8
• 3.7.0-0.2.8
• 3.6.3-0.2.8
• 3.5.4-0.2.8
• etc

As far as I understand - the intent is to allow running unit tests using different versions of Helm engine? However it seems that actual version of Helm engine is statically set in https://github.com/quintush/helm-unittest/blob/master/go.mod#L26

E.g. for the latest tag 0.2.8 - Helm version is set statically to 3.7.1. Then what these different tags mean: 3.7.0-0.2.8, 3.6.3-0.2.8, etc. ?

When I run tests as follows I expected that it would use Helm version 3.5.4 but it's still using 3.7:

docker run -ti --rm -v %cd%/mychart:/apps quintush/helm-unittest:3.5.4-0.2.8 --helm3 -o test-output.xml --output-type JUnit /apps

I used the following Helm template to verify the version of Helm engine in use:

helm-version:
  {{ toYaml .Capabilities.HelmVersion | nindent 2 }}

Hello @lsolovey,

The intent of the different versions, was more related to the helm version itself, not the engine within the unittest plugin.

Some companies are using a specific cliënt version, and the different versions would give the option to use the preferred cliënt version.

With the version 0.3.0 available in the original helm-unittest/helm-unittest, the images only contain the latest version, aligned with the helm unittest engine.

Greetings,
