;;; test-dirvish-config-file-manager-program.el --- Tests for the file-manager dispatch -*- lexical-binding: t; -*-

;;; Commentary:
;; `cj/--file-manager-program-for' is the pure dispatch behind
;; `cj/dirvish-open-file-manager-here'.  Given whether xdg-open is
;; present and the running `system-type', it returns the program name
;; the wrapper should call -- or nil to signal the wrapper should fall
;; back to a shell-command.  Keeping `executable-find' and `system-type'
;; outside lets the helper be tested without faking the live machine.
