;;; test-dev-fkeys--f4-compile-only.el --- Smoke tests for cj/f4-compile-only -*- lexical-binding: t -*-
;;; Commentary:
;; Smoke tests for the C-F4 fast path. On a compiled project, calls
;; `projectile-compile-project'. On an interpreted project, messages
;; "not a compiled language". With no project detected, falls back to
;; plain `compile'.

(require 'ert)
