When I have set the
focus_on
option, and I run all feature tests in cucumber-guard, then a directory path may be sent toFocuser#scan_for_focus_path
. This method tries to callFile#gets
on the directory, and ruby throws a "Is a directory
" error.This patch simply returns an empty array if the file is a directory.
