Testing Linux¶

There are many ways to test the Linux kernel.

Official documentation:

https://docs.kernel.org/dev-tools/testing-overview.html

KUnit¶

KUnit is a framework to run unit tests inside the kernel. They can access internal functions in the kernel, and it is relatively straight forward.

This command will configure, build and run a Linux kernel with KUnit tests:

./tools/testing/kunit/kunit.py run

Userspace tests.

make headers
make -C tools/testing/selftests
make -C tools/testing/selftests run_tests
make kselftest

A distributed test automation system, where many systems run by companies or volunteers run tests automatically and periodically.

If you want to run tests locally without sending data to KernelCI, you need to configure LAVA:
