Instead, enable all tests which have satisfied dependencies by adding ``CONFIG_KUNIT_ALL_TESTS=y`` to your ``.kunitconfig``. +- ``--kunitconfig``: Specifies the path to the ``.kunitconfig`` file. + This Kconfig fragment enables KUnit tests. The "/.kunitconfig" gets + appended to the path specified. For example, If a directory path "lib/kunit" + is given, the complete path will be "lib/kunit/.kunitconfig". + +- ``--kconfig_add``: Specifies additional configuration options to be + appended to the ``.kunitconfig`` file. For example, ``CONFIG_KASAN=y``. + +- ``--arch``: Runs tests with the specified architecture. The architecture + specified must match the string passed to the ARCH make parameter. + For example, i386, x86_64, arm, um, etc. Non-UML architectures run on QEMU. + Default to 'um'. + +- ``--cross_compile``: Specifies the Kbuild toolchain. It passes the + same argument as passed to the ``CROSS_COMPILE`` variable used by + Kbuild. This will be the prefix for the toolchain + binaries such as GCC. For example: + + - ``sparc64-linux-gnu`` if we have the sparc toolchain installed on + our system. + + - ``$HOME/toolchains/microblaze/gcc-9.2.0-nolibc/microblaze-linux/bin/microblaze-linux`` + if we have downloaded the microblaze toolchain from the 0-day + website to a specified path in our home directory called toolchains. + +- ``--qemu_config``: Specifies the path to the file containing a + custom qemu architecture definition. This should be a python file + containing a QemuArchParams object. + +- ``--qemu_args``: Specifies additional QEMU arguments, for example, "-smp 8". + +- ``--jobs``: Specifies the number of jobs (commands) to run simultaneously. + By default, this is set to the number of cores on your system. + +- ``--timeout``: Specifies the maximum number of seconds allowed for all tests to run. + This does not include the time taken to build the tests. + +- ``--kernel_args``: Specifies the kernel command-line arguments. Might be repeated. + +- ``--run_isolated``: If set, boots the kernel for each individual suite/test. + This is useful for debugging a non-hermetic test, one that + might pass/fail based on what ran before it. + +- ``--raw_output``: If set, generates unformatted output from kernel. + If set to ``--raw_output=kunit``, filters to just KUnit output. + +- ``--json``: If set, it stores the test results in a JSON format and prints to stdout or + saves to a file if a filename is specified.
