0N/A# udev-test
0N/A#
0N/A# Provides automated testing of the udev binary.
0N/A# The whole test is self contained in this file, except the matching sysfs tree.
0N/A# Simply extend the @tests array, to add a new test variant.
0N/A#
0N/A# Every test is driven by its own temporary config file.
0N/A# This program prepares the environment, creates the config and calls udev.
0N/A#
0N/A# udev reads the config, looks at the provided sysfs and
0N/A# first creates and then removes the device node.
0N/A# After creation and removal the result is checked against the
0N/A# expected value and the result is printed.
0N/A#
0N/A# happy testing,
0N/A# Kay Sievers <kay.sievers@vrfy.org>, 2003
