This patch adds the kunit.enable module parameter that will need to be set to true in addition to KUNIT being enabled for KUnit tests to run. The default value is true giving backwards compatibility. However, for the production+testing use case the new config option KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in by passing kunit.enable=1 to the kernel.

Enables support for kernel unit tests (KUnit), 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 when using UML. Can also be used on most other
|
|
architectures. For more information, please see

Enable debugfs representation for kunit. Currently this consists

Enables the unit tests for the KUnit test framework. These tests test

the KUnit test framework itself; the tests are both written using

KUnit and test KUnit. This option should only be enabled for testing

purposes by developers interested in testing that KUnit works as

expected.

Enables an example unit test that illustrates some of the basic

features of KUnit. This test only exists to help new users understand
|
|
what KUnit is and how it is used. Please refer to the example test
|
|
itself, lib/kunit/example-test.c, for more information. This option
|

is intended for curious hackers who would like to understand how to
|
|
use KUnit for kernel development.

Enables all KUnit tests, if they can be enabled.

KUnit tests run during boot and output the results to the debug log
|

in TAP format (http://testanything.org/). Only useful for kernel devs
|
|
running the KUnit test harness, and not intended for inclusion into a
|
|
production build.
|
|
|

For more information on KUnit and unit tests in general please refer

to the KUnit documentation in Documentation/dev-tools/kunit/.

Sets the default value of kunit.enable. If set to N then KUnit
|
|
tests will not execute unless kunit.enable=1 is passed to the
|
|
kernel command line.
|
|
|
|
In most cases this should be left as Y. Only if additional opt-in
|
|
behavior is needed should this be set to N.
