FWIW you should see these if you run golint or gometalinter too. Running http://goconvey.co/ locally can be useful too.

Test target runs:

.PHONY: test
test: lint bindata_assetfs.go
        @go test -cover `go list ./... | grep -v /vendor/`

yet it didn't complain about those test files which I need to look into
but codacy does more linting, that's why I was testing it

In cloudflare-go we run go vet and golint in Travis too: https://github.com/cloudflare/cloudflare-go/blob/master/.travis.yml
