+ KUnit can be enabled or disabled at boot time, and this behavior is
+ controlled by the kunit.enable kernel parameter.
+ By default, kunit.enable is set to 1 because KUNIT_DEFAULT_ENABLED is

Once we have built our kernel (and/or modules), it is simple to run
the tests. If the tests are built-in, they will run automatically on the
kernel boot. The results will be written to the kernel log (``dmesg``)
