;;; test-dev-fkeys--f4-dispatch.el --- Tests for cj/--f4-dispatch -*- lexical-binding: t -*-

;; Tests for the dispatch router. Each known action symbol routes to the
;; corresponding command. Unknown actions raise user-error. The action
;; handlers themselves are tested in their own files; this file only
;; verifies the routing layer.
