;;; test-dev-fkeys--projectile-advice-install.el --- Tests for Projectile advice setup -*- lexical-binding: t -*-

;; Smoke tests for the load-order contract between dev-fkeys.el and Projectile.
;; Requiring dev-fkeys should not force Projectile to load, but the command-cache
;; revert advice should be installed once Projectile is available.
