;;; test-video-audio-recording--label-devices.el --- Tests for device labeling -*- lexical-binding: t; -*-
;;; Commentary:
;; Unit tests for cj/recording--label-devices.
;; Verifies label formatting ("Description [status]") and sort order
;; (in use → ready → available → muted).
;; Also indirectly tests cj/recording--device-sort-key and
;; cj/recording--device-status-label since they are trivial helpers
;; consumed entirely by label-devices.
;;; Code:
(require 'ert)
;; Stub dependencies before loading the module
(defvar cj/custom-keymap (make-sparse-keymap)
"Stub keymap for testing.")
