;;; test-ai-term--shutdown-countdown.el --- Tests for the shutdown countdown -*- lexical-binding: t; -*-
;;; Commentary:
;; The "wrap it up and shutdown" countdown. The testable logic is the safety
;; gate (abort when more than one aiv-* session is live) and the cancel/timer
;; bookkeeping; the tick rendering and the actual shutdown side effect are
;; manual (see the spec). shell-command is stubbed throughout so no test can
;; power the machine off, and timers are cancelled rather than allowed to fire.
;;; Code:
(require 'ert)
(require 'cl-lib)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(require 'ai-term)
