;;; Commentary:
;; Unit tests for cj/recording-quick-setup-for-calls function.
;; Tests quick device setup workflow for call recording.

;;; Code:

(require 'ert)

;; Stub dependencies before loading the module
(defvar cj/custom-keymap (make-sparse-keymap)
  "Stub keymap for testing.")

;; Now load the actual production module
(require 'video-audio-recording)
