test: Kappa go test tests don't work with a simple `go test ./...`

test: full suite of Kappa go test tests don't work with a simple `go test ./...` in some environments.
I believe it may have to do with some setup requirement in the pipeline tests. It would be great if they just worked with `go test ./...`

Start by running `go test ./...` and focus on the Kappa pipeline tests mentioned in the issue. Identify which setup requirement causes failures in some environments, then confirm that the full suite runs successfully with the same command without special setup.
