@dougm Well, let's add it to `go-test` as well then.  It won't do no harm if `errcheck` ignores test cases, but if it is ever changed to check test cases as well, it'll just work automatically for Flycheck as well.

And it'd stop me from ever wondering about the rationale behind adding it to one, but not to the other.

By the way, thanks for your extraordinary patience on following through all my nitpicky remarks and comments :)
