4 # udev test
5 #
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 #
13 # udev parses the rules, looks at the provided sysfs and
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.
