;;; Commentary:

;; This is the test suite for `dired-rmjunk', separated from `dired-rmjunk.el'
;; so that loading `ert' isn't a requirement to use the tool.

;; The suite can be run with the following shell command:

;; emacs -Q --batch --directory ./ --directory ./t --load t/dired-rmjunk-test.el --funcall ert-run-tests-batch-and-exit
