3 # udev test
4 #
5 # Provides automated testing of the udev binary.
6 # The whole test is self contained in this file, except the matching sysfs tree.
7 # Simply extend the @tests array, to add a new test variant.
8 #
9 # Every test is driven by its own temporary config file.
10 # This program prepares the environment, creates the config and calls udev.
11 #
12 # udev parses the rules, looks at the provided sysfs and
13 # first creates and then removes the device node.
14 # After creation and removal the result is checked against the
15 # expected value and the result is printed.
