Don't rely on a magic version tag, instead let a device define a udev rule and drop that into the udev runtime directory before the device is created. There are a couple of caveats with this approach: first, since this changes system-wide state it may cause issues on the device the test suite is run on. This can be avoided if the udev rules have filter patterns that ensure only test devices are affected. Second, the check test suite aborts but it doesn't run the teardown() function if a test fails. So far this wasn't a problem since uinput devices disappear whenever we exit. The rules files will hang around though, so an unchecked fixture was added to delete all litest-foo.rules files before and after a test case starts. Unchecked fixtures are run regardless of the exit status of the test but run in the same address space - i.e. no ck_assert() usage. Also unchecked fixtures are only run once per test-case, not once per test function. For us, that means they're only run once per device (we use the devices as test case), i.e. if a test fails and the udev rule isn't tidied up, the next test may be unpredictable. This shouldn't matter too much though. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com>
