# 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 RULES to add a new test.
|
|
#
|
|
# 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.
