| 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. |
| $ make -C tools/testing/selftests |
| $ 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 |
| In general, the rules for for selftests are |
| * Do as much as you can if you're not root; |
| * Don't break the build on any architecture, and |
| * Don't cause the top-level "make run_tests" to fail if your feature is |
