There was a problem hiding this comment. I prefer using See the following PR as an example: There was a problem hiding this comment. Yea, I kept it the way it is because it is consistent with all the other tests for istio There was a problem hiding this comment. sure.. but we have to start somewhere ¯\_(ツ)_/¯ |
