-;;; test-custom-buffer-file-copy-to-bottom-of-buffer.el --- Tests for cj/copy-to-bottom-of-buffer -*- lexical-binding: t; -*-
-
-;;; Commentary:
-;; Tests for the cj/copy-to-bottom-of-buffer function from custom-buffer-file.el
-;;
-;; This function copies all text from point to the end of the current buffer
-;; to the kill ring without modifying the buffer.
-
-;;; Code:
-
-(require 'ert)
-(require 'testutil-general)
-
-;; Add modules directory to load path
-(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
-
-;; Stub dependencies before loading the module
-(defvar cj/custom-keymap (make-sparse-keymap)
- "Stub keymap for testing.")
-
-;; Stub ps-print package
-(provide 'ps-print)
-
-;; Now load the actual production module
-(require 'custom-buffer-file)
