-;;; test-music-config--collect-entries-recursive.el --- Tests for recursive music collection -*- coding: utf-8; lexical-binding: t; -*-
-;;
-;; Author: Craig Jennings <c@cjennings.net>
-;;
-;;; Commentary:
-;; Unit tests for cj/music--collect-entries-recursive function.
-;; Tests the recursive helper that collects music files and directories.
-;;
-;; Test organization:
-;; - Normal Cases: Single level, nested directories, mixed files
-;; - Boundary Cases: Hidden files/dirs, non-music files, empty dirs, sorting
-;; - Error Cases: Empty root, nonexistent root
-;;
-;;; Code:
-
-(require 'ert)
-(require 'testutil-general)
-
-;; Stub missing dependencies before loading music-config
-(defvar-keymap cj/custom-keymap
-  :doc "Stub keymap for testing")
-
-;; Load production code
-(require 'music-config)
