History

Michael Ellerman cbfd7dab2d selftests/powerpc: Don't ignore errors from sub Makefiles Currently we ignore errors from our sub Makefiles. We inherited that from the top-level selftests Makefile which aims to build and run as many tests as possible and damn the torpedoes. For the powerpc tests we'd instead like any errors to fail the build, so we can automatically catch build failures. We can achieve the best of both worlds by using -k, which tells make to keep building when it hits an error, but still reports the error.

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.
