It would be great if you can include your test results in the helm tests https://github.com/nginx/kubernetes-ingress/blob/main/charts/tests/helmunit_test.go

I added the test, i didn't find a doc to guide how to add tests, but I think I did it right. Can you double-check to make sure everything is alright?

After adding tests, I ran:

make test 

Result:

go test -tags=aws,helmunit -shuffle=on ./... ok github.com/nginx/kubernetes-ingress/charts/tests 30.322s

Thanks @rodrigosandrin for adding these!

No docs on how to do tests but what you have done looks good!

We will review when we have a chance!
