Linux Kernel Selftests
|
||
|
|
|
||
|
|
The kernel contains a set of "self tests" under the tools/testing/selftests/
|
||
|
|
directory. These are intended to be small unit tests to exercise individual
|
||
|
|
code paths in the kernel.
|
||
|
|
|
||
|
|
Running the selftests
|
||
|
|
=====================
|
||
|
|
|
||
|
|
To build the tests:
|
||
|
|
|
||
|
|
$ make -C tools/testing/selftests
|
||
|
|
|
||
|
|
|
||
|
|
To run the tests:
|
||
|
|
|
||
|
|
$ make -C tools/testing/selftests run_tests
|
||
|
|
|
||
|
|
- note that some tests will require root privileges.
|
||
|
|
|
||
|
|
|
||
|
|
To run only tests targetted for a single subsystem:
|
||
|
|
|
||
|
|
$ make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests
|
||
|
|
|
||
|
|
See the top-level tools/testing/selftests/Makefile for the list of all possible
|
||
|
|
targets.
|
||
|
|
|
||

Contributing new tests
|
||
|
|
======================
|
||
|
|
|
||
|
|
In general, the rules for for selftests are
|
||
|
|
|
||
|
|
* Do as much as you can if you're not root;
|
||
|
|
|
||
|
|
* Don't take too long;
|
||
|
|
|
||
|
|
* Don't break the build on any architecture, and
|
||
|
|
|
||
|
|
* Don't cause the top-level "make run_tests" to fail if your feature is
|
||
|
|
unconfigured.
