   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 reads the config, 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.
  16 #
  17 # happy testing,

  20 # Modified April 9, 2004 by Leann Ogasawara <ogasawara@osdl.org>
  21 #  - expanded @tests array to add more symlinks and permissions tests
  22 #  - some of the symlinks tests also test lack of node creation
  23 #  - added symlink_test() function
  24 #  - moved permissions and major_minor tests into their own functions
