Please remove the random string added to the pod name of the test pods

[Reza Farrahi M]

Hi, Please remove the random string added to the pod name for test pods. This will help to be able to skip a test using its predictable name.
Below is an example (from https://github.com/stefanprodan/podinfo/blob/master/charts/podinfo/templates/tests/grpc.yaml):

  name: {{ template "podinfo.fullname" . }}-grpc-test-{{ randAlphaNum 5 | lower }}

Please change it to:

  name: {{ template "podinfo.fullname" . }}-grpc-test

Thanks
