;;; test-user-constants.el --- Tests for user-constants path init -*- lexical-binding: t; -*-
;;; Commentary:
;; user-constants defines the config's path constants and creates the
;; configured directories/files. After the split, loading the module is
;; side-effect-free: creation happens only when
;; cj/initialize-user-directories-and-files is called (from init.el on real
;; startup). These tests sandbox user-emacs-directory and user-home-dir so the
;; path defconsts resolve into temp dirs, then check that loading creates
;; nothing, the initializer creates what it should, and the verify-or-create
;; helpers report required vs optional failures differently.
;;; Code:
(require 'ert)
(require 'cl-lib)
;; Declare special so the macro's let-bindings are dynamic — the module
;; `defvar's user-home-dir at load, which errors if the var is lexically bound.
;; user-emacs-directory is already special (built-in).
