6# Provides automated testing of the udev binary.
7# The whole test is self contained in this file, except the matching sysfs tree.
8# Simply extend the @tests array, to add a new test variant.
9#
10# Every test is driven by its own temporary config file.
11# This program prepares the environment, creates the config and calls udev.
12#
65005a7f 13# udev parses the rules, looks at the provided sysfs and
a367f04e
GKH		 14# first creates and then removes the device node.
15# After creation and removal the result is checked against the
16# expected value and the result is printed.
