Hi @huww98. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

ginkgo.GinkgoHelper didn't exist when this code was written. Using it indeed is simpler.

We want to treat all methods as helpers, right? Then some ginkgo.GinkgoHelper calls are missing.

Yes, but so long as one of the callers has GinkgoHelper(), it should be fine. And I think registerXxx() is not intended to be called outside of resources.go. e.g. registerVolume is called from CreateVolume, which has GinkgoHelper

Yes, but so long as one of the callers has GinkgoHelper(), it should be fine.

That's not my understanding of how that function works. GinkgoHelper marks "the function it's called in as a test helper" (emphasis mine). It does not mark the function and all functions called by it as helper.

[huww98]

Yes, you are correct. I just experimented and confirmed that every function in the stack should have GinkgoHelper(). Thank you.
