@mmorel-35 could you explain what was done?

you ran something like lint-fix removing this

velero/golangci.yaml

Lines 36 to 37 in 13f4efd

	skip-files:
	- ".*_test.go$"

, then manually resolved the "expect err (not)to HaveOccurred" ginkgolinter error and then added config back to golangci.yaml?

If the intent is to fix all mentioned error from ginkgolinter, maybe also need to remove this from golangci.yaml

velero/golangci.yaml

Lines 21 to 22 in 13f4efd

	skip-dirs:
	- test/*

[mmorel-35]

I did a golangci fix after removing _test.go then fix Ginkgolinter errors concerning expect.
I would not modify golangci config just for this now.
After my two PR are merged I would start by removing exclude file to use exclude rules instead and then fix them one after the other

[mmorel-35]

I believe it’s better to keep this pr a draft until #7573 is merged and then turn it into a full fix of ginkgolinter issues
