;;; test-dev-fkeys--detect-project-type.el --- Tests for cj/--detect-project-type -*- lexical-binding: t -*-
;;; Commentary:
;; Tests for the project-type classifier in dev-fkeys.el.
;; The classifier returns 'compiled, 'interpreted, or 'unknown based on
;; marker files at the project root. Interpreted markers are checked first
;; so a Python or Node project with a Makefile for tasks classifies as
;; interpreted.
;;; Code:
(require 'ert)

(require 'dev-fkeys)

"Create a temp project dir with each filename in MARKERS as an empty file.
Bind the dir path to ROOT in BODY. Cleans up on exit."
