5 The kernel contains a set of "self tests" under the tools/testing/selftests/

138 tool) to install selftests in the default location (`tools/testing/selftests/kselftest_install`),
143    $ make -C tools/testing/selftests install

267     * the part of paths below tools/testing/selftests/ is preserved when
282    e.g: tools/testing/selftests/android/config
296     make -C tools/testing/selftests {all,install,clean,gen_tar}
297     make -C tools/testing/selftests {all,install,clean,gen_tar} O=abs_path

304 testing from within the kernel, one method of doing this is to create a
310 - ``tools/testing/selftests/kselftest_module.h``
311 - ``tools/testing/selftests/kselftest/module.sh``
314 happen automatically for modules which are in the ``tools/testing/``
330    e.g. ``tools/testing/selftests/lib/printf.sh``
332 3. Add line to config file e.g. ``tools/testing/selftests/lib/config``
334 4. Add test script to makefile  e.g. ``tools/testing/selftests/lib/Makefile``
358    #include "../tools/testing/selftests/kselftest_module.h"
363     * Kernel module for testing the foobinator
395 test harness is for userspace testing, for kernel space testing see `Test
398 The tests from tools/testing/selftests/seccomp/seccomp_bpf.c can be used as
