;;; test-custom-file-buffer-copy-path-to-buffer-file-as-kill.el --- Tests for cj/copy-path-to-buffer-file-as-kill -*- lexical-binding: t; -*-
;;; Commentary:
;; Tests for the cj/copy-path-to-buffer-file-as-kill function from custom-file-buffer.el
;;
;; This function copies the full path of the current buffer's file to the kill ring
;; and returns the path. It signals an error if the buffer is not visiting a file.
;;; 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-file-buffer)
;;; Setup and Teardown
(defun test-copy-path-setup ()
"Set up test environment."
(setq kill-ring nil))
