;;; 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.
;;; Code:
(require 'ert)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(add-to-list 'load-path (expand-file-name "tests" user-emacs-directory))

(ert-deftest test-prog-go-format-executable-on-path ()
