The directory contains one file + +- results: "cat results" displays results of each test case and the results + of the entire suite for the last test run. + +The debugfs representation is primarily of use when kunit test suites are +run in a native environment, either as modules or builtin. Having a way +to display results like this is valuable as otherwise results can be +intermixed with other events in dmesg output. The maximum size of each +results file is KUNIT_LOG_SIZE bytes (defined in include/kunit/test.h).
