Possible options are: + + - ``all``: To view the full kernel output, use ``--raw_output=all``. + + - ``kunit``: This is the default option and filters to KUnit output. Use ``--raw_output`` or ``--raw_output=kunit``. + +- ``--json``: If set, stores the test results in a JSON format and prints to `stdout` or + saves to a file if a filename is specified.
