#!/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 parses the rules, 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. # # Copyright (C)
