;;; test-wttrin-debug-aliases.el --- Tests for obsolete debug aliases -*- lexical-binding: t; -*-

;; Copyright (C) 2026 Craig Jennings

;;; Commentary:

;; The four `debug-wttrin-*' names were renamed to `wttrin-debug-*' in
;; 0.4.0 to follow the package-prefix convention.  The old names remain
;; as obsolete aliases so existing keybindings keep working.  These tests
;; verify each alias resolves to the new function and is marked obsolete
;; with the expected target and version.

;;; Code:

(require 'ert)
(require 'wttrin)
(require 'testutil-wttrin)

(require 'wttrin-debug
         (expand-file-name "wttrin-debug.el"
