#!/usr/bin/perl # udev-test # # Provides automated testing of the udev binary. # The whole test is self contained in this file, except the matching sysfs tree. # Simply extend the @tests array, to add a new test variant. # # Every test is driven by its own temporary config file. # This program prepares the environment, creates the config and calls udev. # # udev reads the config, looks at the provided sysfs and # first creates and then removes the device node. # After creation and removal the result is checked against the # expected value and the result is printed. # # happy testing, # Kay Sievers <kay.sievers@vrfy.org>, 2003 use warnings; use strict; my $PWD = $ENV{PWD}; my $sysfs = "sys/"; my $udev_bin = "../udev"; my $udev_root = "udev-root/"; #
