;;; test-video-audio-recording-quick-setup.el --- Tests for cj/recording-quick-setup -*- lexical-binding: t; -*-

;;; Commentary:
;; Unit tests for cj/recording-quick-setup function.
;; The quick setup shows available mics and auto-selects the default
;; sink's monitor for system audio capture.

;;; 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)

;;; Setup and Teardown

(defun test-quick-setup-setup ()
  "Reset device variables before each test."
  (setq cj/recording-mic-device nil)
  (setq cj/recording-system-device nil))

(defun test-quick-setup-teardown ()
  "Clean up device variables after each test."
  (setq cj/recording-mic-device nil)
  (setq cj/recording-system-device nil))
