   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.
