Install selftests
=================
You can use the kselftest_install.sh tool to install selftests in the
default location, which is tools/testing/selftests/kselftest, or in a
user specified location.
You can use the "install" target of "make" (which calls the `kselftest_install.sh`
tool) to install selftests in the default location (`tools/testing/selftests/kselftest_install`),
or in a user specified location via the `INSTALL_PATH` "make" variable.
To install selftests in default location::
$ cd tools/testing/selftests
$ ./kselftest_install.sh
$ make -C tools/testing/selftests install
To install selftests in a user specified location::
$ cd tools/testing/selftests
$ ./kselftest_install.sh install_dir
$ make -C tools/testing/selftests install INSTALL_PATH=/some/other/path
Running installed selftests
===========================
Kselftest install as well as the Kselftest tarball provide a script
named "run_kselftest.sh" to run the tests.
Found in the install directory, as well as in the Kselftest tarball,
is a script named `run_kselftest.sh` to run the tests.
You can simply do the following to run the installed Kselftests. Please
note some tests will require root privileges::
$ cd kselftest
$ cd kselftest_install
$ ./run_kselftest.sh
To see the list of available tests, the `-l` option can be used::
$ ./run_kselftest.sh -l
The `-c` option can be used to run all the tests from a test collection, or
the `-t` option for specific single tests. Either can be used multiple times::
$ ./run_kselftest.sh -c bpf -c seccomp -t timers:posix_timers -t timer:nanosleep
For other features see the script usage output, seen with the `-h` option.
