linux-kselftest-kunit-5.7-rc1
This kunit update for Linux-5.7-rc1 consists of:
- debugfs support for displaying kunit test suite results; this is
especially useful for module-loaded tests to allow disentangling of
test result display from other dmesg events. CONFIG_KUNIT_DEBUGFS
enables/disables the debugfs support.
- Several fixes and improvements to kunit framework and tool.

|
|||
==============
|
||||
|
||||
KUnit is a lightweight unit testing and mocking framework for the Linux kernel.
|
||||
These tests are able to be run locally on a developer's workstation without a VM
|
||||
or special hardware.
|
||||
|
||||
KUnit is heavily inspired by JUnit, Python's unittest.mock, and
|
||||
Googletest/Googlemock for C++. KUnit provides facilities for defining unit test
|
||||
cases, grouping related test cases into test suites, providing common
|
||||
infrastructure for running tests, and much more.
|
||||
|
||||
KUnit consists of a kernel component, which provides a set of macros for easily
|
||||
writing unit tests. Tests written against KUnit will run on kernel boot if
|
||||
built-in, or when loaded if built as a module. These tests write out results to
|
||||
the kernel log in `TAP <https://testanything.org/>`_ format.
|
||||
|
||||
To make running these tests (and reading the results) easier, KUnit offers
|
||||
:doc:`kunit_tool <kunit-tool>`, which builds a `User Mode Linux
|
||||
<http://user-mode-linux.sourceforge.net>`_ kernel, runs it, and parses the test
|
||||
results. This provides a quick way of running KUnit tests during development,
|
||||
without requiring a virtual machine or separate hardware.

possible if the code under test is very small and does not have any external
|

dependencies outside of the test's control like hardware.
|
||||
|
||||
Outside of KUnit, there are no testing frameworks currently
|
||||
available for the kernel that do not require installing the kernel on a test
|
||||
machine or in a VM and all require tests to be written in userspace running on
|
||||
the kernel; this is true for Autotest, and kselftest, disqualifying
|
||||
any of them from being considered unit testing frameworks.
|
||||
KUnit provides a common framework for unit tests within the kernel.
|
||||
|
||||
KUnit addresses the problem of being able to run tests without needing a virtual
|
||||
machine or actual hardware with User Mode Linux. User Mode Linux is a Linux
|
||||
architecture, like ARM or x86; however, unlike other architectures it compiles
|
||||
to a standalone program that can be run like any other program directly inside
|
||||
of a host operating system; to be clear, it does not require any virtualization
|
||||
support; it is just a regular program.
|
||||
KUnit tests can be run on most architectures, and most tests are architecture
|
||||
independent. All built-in KUnit tests run on kernel startup. Alternatively,
|
||||
KUnit and KUnit tests can be built as modules and tests will run when the test

module is loaded.

can be used with UML either by building with ``ARCH=um`` (like any other
|
||||
architecture), or by using :doc:`kunit_tool <kunit-tool>`.

KUnit is fast. Excluding build time, from invocation to completion KUnit can run

|

Creating a .kunitconfig
|
||||
=======================
|
||||
The Python script is a thin wrapper around Kbuild. As such, it needs to be
|
||||
configured with a ``.kunitconfig`` file. This file essentially contains the
|
||||
regular Kernel config, with the specific test targets as well.
|
||||
-----------------------
|
||||
If you want to run a specific set of tests (rather than those listed in the
|
||||
KUnit defconfig), you can provide Kconfig options in the ``.kunitconfig`` file.
|
||||
This file essentially contains the regular Kernel config, with the specific
|
||||
test targets as well. The ``.kunitconfig`` should also contain any other config
|
||||
options required by the tests.
|
||||
|
||||
A good starting point for a ``.kunitconfig`` is the KUnit defconfig:
|
||||
.. code-block:: bash
|
||||
|
||||
cd $PATH_TO_LINUX_REPO
|
||||
cp arch/um/configs/kunit_defconfig .kunitconfig
|
||||
|
||||
Verifying KUnit Works
|
||||
---------------------
|
||||
You can then add any other Kconfig options you wish, e.g.:
|
||||
.. code-block:: none
|
||||
|
||||
CONFIG_LIST_KUNIT_TEST=y
|
||||
|
||||
:doc:`kunit_tool <kunit-tool>` will ensure that all config options set in
|
||||
``.kunitconfig`` are set in the kernel ``.config`` before running the tests.
|
||||
It'll warn you if you haven't included the dependencies of the options you're
|
||||
using.
|
||||
|
||||
.. note::
|
||||
Note that removing something from the ``.kunitconfig`` will not trigger a
|
||||
rebuild of the ``.config`` file: the configuration is only updated if the
|
||||
``.kunitconfig`` is not a subset of ``.config``. This means that you can use
|
||||
other tools (such as make menuconfig) to adjust other config options.
|
||||
|
||||
|
||||
Running the tests

||||

Running tests without the KUnit Wrapper
|
||||
=======================================
|
||||
|
||||
If you'd rather not use the KUnit Wrapper (if, for example, you need to
|
||||
integrate with other systems, or use an architecture other than UML), KUnit can
|
||||
be included in any kernel, and the results read out and parsed manually.
|

.. note::

||||
KUnit is not designed for use in a production system, and it's possible that
|
||||
tests may reduce the stability or security of the system.
|
||||
|
||||
|
||||
|
||||
Configuring the kernel
|
||||
----------------------
|
||||
|
||||
In order to enable KUnit itself, you simply need to enable the ``CONFIG_KUNIT``
|
||||
Kconfig option (it's under Kernel Hacking/Kernel Testing and Coverage in
|
||||
menuconfig). From there, you can enable any KUnit tests you want: they usually
|
||||
have config options ending in ``_KUNIT_TEST``.
|
||||
|
||||
KUnit and KUnit tests can be compiled as modules: in this case the tests in a
|
||||
module will be run when the module is loaded.
|
||||
|
||||
Running the tests

-----------------
|

Build and run your kernel as usual. Test output will be written to the kernel

log in `TAP <https://testanything.org/>`_ format.

KUnit debugfs representation
|

============================
|

When kunit test suites are initialized, they create an associated directory

of the entire suite for the last test run.

The debugfs representation is primarily of use when kunit test suites are

run in a native environment, either as modules or builtin. Having a way
|

to display results like this is valuable as otherwise results can be
