Here are the tests for the enumeration character %e. I've added a option
string to be able to do a whole sequence of tests without node removal,
so we can skip the "remove" event and get an increasing number to append
to the name. After the sequence test the whole directory is cleaned for
the next tests.

#!/usr/bin/perl
# udev-test
#
# Provides automated testing of the udev binary.
# The whole test is self contained in this file, except the matching sysfs tree.
# Simply extend the @tests array, to add a new test variant.
#
# Every test is driven by its own temporary config file.
# This program prepares the environment, creates the config and calls udev.
#
# udev reads the config, looks at the provided sysfs and
# first creates and then removes the device node.
# After creation and removal the result is checked against the
# expected value and the result is printed.
#
# happy testing,
# Kay Sievers <kay.sievers@vrfy.org>, 2003
#
# Modified April 9, 2004 by Leann Ogasawara <ogasawara@osdl.org>
# - expanded @tests array to add more symlinks and permissions tests
# - some of the symlinks tests also test lack of node creation
# - added symlink_test() function
# - moved permissions and major_minor tests into their own functions
