Input: Add KUnit tests for some of the input core helper functions The input subsystem doesn't currently have any unit tests, let's add a CONFIG_INPUT_KUNIT_TEST option that builds a test suite to be executed with the KUnit test infrastructure. For now, only three tests were added for some of the input core helper functions that are trivial to test: * input_test_polling: set/get poll interval and set-up a poll handler. * input_test_timestamp: set/get input event timestamps. * input_test_match_device_id: match a device by bus, vendor, product, version and events capable of handling. But having the minimal KUnit support allows to add more tests and suites as follow-up changes. The tests can be run with the following command: $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/input/tests/ Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Enric Balletbo i Serra <eballetbo@redhat.com> config: powerpc-allnoconfig (https://download.01.org/0day-ci/archive/20230330/202303301815.kRKFM3NH-lkp@intel.com/config) Link: https://lore.kernel.org/r/20230330081831.2291351-1-javierm@redhat.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> 2023-04-01 22:45:09 -07:00
