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.
+
Packaging selftests
===================
$ make -C tools/testing/selftests gen_tar
This generates a tarball in the `INSTALL_PATH/kselftest-packages` directory. By
-default, `.gz` format is used. The tar format can be overridden by specifying
-a `FORMAT` make variable. Any value recognized by `tar's auto-compress`_ option
-is supported, such as::
