;;; test-keyboard-compat--icon-blank-in-terminal.el --- Tests for cj/--icon-blank-in-terminal -*- lexical-binding: t; -*-
;;; Commentary:
;; Tests for the per-call icon-rendering gate that replaced the load-time
;; defun-redefinition. The helper must dispatch on the current frame's
;; `display-graphic-p' so the same daemon can serve real icons to GUI frames
;; and blanks to terminal frames.

(require 'ert)
(require 'cl-lib)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(require 'keyboard-compat)
