These optional functions can be defined by a test case script. When defined and TEST_DEVS is empty, the fallback_device() is executed before runing the test case. The fallback_device() function intializes a virtual device to run the test case and return the device to be set in TEST_DEVS. After running the test case, cleanup_fallback_device() is executed to clean up the device. This feature allows to run test cases with test_device() function even if TEST_DEVS is not set in the config, using virtaul devices such as null_blk.
