;;; test-custom-ordering-arrayify.el --- Tests for cj/--arrayify -*- lexical-binding: t; -*-
;;; Commentary:
;; Tests for the cj/--arrayify function from custom-ordering.el
;;
;; This function converts lines of text into a quoted, comma-separated array format.
;; It splits input by whitespace, wraps each element in quotes, and joins with ", ".
;;
;; Examples:
;; Input: "apple\nbanana\ncherry"
;; Output: "\"apple\", \"banana\", \"cherry\""
;;
;; Input: "one two three" (with single quotes)
;; Output: "'one', 'two', 'three'"
;;
;; We test the NON-INTERACTIVE implementation (cj/--arrayify) to avoid
;; mocking user input for quote characters. This follows our testing best
;; practice of separating business logic from UI interaction.
;;; 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.")
;; Now load the actual production module
(require 'custom-ordering)
