;;; test-prog-go--format-wiring.el --- Verify the Go formatter is wired -*- lexical-binding: t; -*-

;;; Commentary:
;; Go's binding is installed via `local-set-key' inside the
;; `cj/go-mode-keybindings' hook, not via use-package's `:bind'. The
;; test runs the hook directly in a temp buffer and asks the buffer-
;; local map what C-; f resolves to.
;;
;; Three checks:
;;   1. `gofmt' is fboundp after go-mode loads.
;;   2. The hook installs C-; f → `gofmt' in the buffer-local map.
;;   3. `gofmt' (or `goimports') is on PATH.
