;;; test-dev-fkeys--projectile-around-revert.el --- Tests for cj/--projectile-around-revert -*- lexical-binding: t -*-
;;; Commentary:
;; Tests for the around-advice that wires the capture / finish-hook pair
;; to projectile cmd runners. The advice:
;;
;; 1. Captures the prior cached cmd via `cj/--projectile-capture-cmd'.
;; 2. Adds `cj/--projectile-revert-on-fail' to `compilation-finish-functions'.
;; 3. Calls ORIG-FN with ARGS so projectile's normal flow proceeds.
;;; Code:
(require 'ert)
(require 'cl-lib)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(require 'dev-fkeys)
