;;; test-elfeed-config--decode-html-entities.el --- Tests for cj/--decode-html-entities -*- lexical-binding: t; -*-

;;; Commentary:
;; cj/--decode-html-entities replaces the six inline replace-regexp-in-string
;; calls that cj/youtube-to-elfeed-feed-format used to hand-decode an og:title.

;;; Code:

(require 'ert)

(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(require 'elfeed-config)
