1Linux Kernel Selftests

3The kernel contains a set of "self tests" under the tools/testing/selftests/
4directory. These are intended to be small unit tests to exercise individual
5code paths in the kernel.

7Running the selftests
8=====================

10To build the tests:
11
12 $ make -C tools/testing/selftests
13
14
15To run the tests:
16
17 $ make -C tools/testing/selftests run_tests

22To run only tests targetted for a single subsystem:
23
24 $ make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests

33In general, the rules for for selftests are
34
35 * Do as much as you can if you're not root;
36
37 * Don't take too long;
38
39 * Don't break the build on any architecture, and
40
41 * Don't cause the top-level "make run_tests" to fail if your feature is
42 unconfigured.
