this should be fixed in the codecov.yml file, this is a hack more or less

https://github.com/cosmos/cosmos-sdk/blob/master/.codecov.yml#L49

For some reason these files are still reported as untested, e.g.:

https://codecov.io/gh/cosmos/cosmos-sdk/src/master/types/types.pb.go

yea there is a weird bug with that. In this PR #5493 it seems to have done it correctly. maybe we wait to merge that to see what happens.

also in the next release of protogen-go-gocosmos it will default to create the test files for the autogenerated files

Ok that makes total sense. Hence closing. Thanks!
