| # 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. |
