1 | Linux Kernel Selftests |
| 2 | ||
| 3 | The kernel contains a set of "self tests" under the tools/testing/selftests/ | |
| 4 | directory. These are intended to be small unit tests to exercise individual | |
| 5 | code paths in the kernel. | |
| 6 | ||
| 7 | Running the selftests | |
| 8 | ===================== | |
| 9 | ||
| 10 | To build the tests: | |
| 11 | ||
| 12 | $ make -C tools/testing/selftests | |
| 13 | ||
| 14 | ||
| 15 | To run the tests: | |
| 16 | ||
| 17 | $ make -C tools/testing/selftests run_tests | |
| 18 | ||
| 19 | - note that some tests will require root privileges. | |
| 20 | ||
| 21 | ||
| 22 | To run only tests targetted for a single subsystem: | |
| 23 | ||
| 24 | $ make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests | |
| 25 | ||
| 26 | See the top-level tools/testing/selftests/Makefile for the list of all possible | |
| 27 | targets. | |
| 28 | ||
| 29 | ||
| 30 | Contributing new tests | |
| 31 | ====================== | |
| 32 | ||
| 33 | In 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. |
