;;; test-dev-fkeys--projectile-reset-cmds.el --- Tests for cj/projectile-reset-cmds -*- lexical-binding: t -*-
;;; Commentary:
;; Tests for the manual escape-hatch command that clears projectile's
;; per-project compile / test / run cache for the current project. Use
;; case: projectile's auto-derived default was wrong to begin with and
;; you want to reset to projectile's default-derived cmd at the next
;; prompt.

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