;;; test-video-audio-recording--label-sinks.el --- Tests for sink labeling -*- lexical-binding: t; -*-
;;; Commentary:
;; Unit tests for cj/recording--label-sinks.
;; Verifies that sink labels include app names for active sinks,
;; e.g. "JDS Labs [in use] (Firefox)" and sort correctly.
;;; Code:
(require 'ert)
;; Stub dependencies before loading the module
(defvar cj/custom-keymap (make-sparse-keymap)
"Stub keymap for testing.")
(require 'video-audio-recording)

(defun test-label-sinks--stub (sink-apps-alist sinks-short-output)

;; We use cl-letf in each test to stub both get-sink-apps and
