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, | |
