2 # KUnit base configuration
6 tristate "KUnit - Enable support for unit tests"
9 Enables support for kernel unit tests (KUnit), a lightweight unit
10 testing and mocking framework for the Linux kernel. These tests are
11 able to be run locally on a developer's workstation without a VM or
12 special hardware when using UML. Can also be used on most other
13 architectures. For more information, please see
14 Documentation/dev-tools/kunit/.
19 bool "KUnit - Enable /sys/kernel/debug/kunit debugfs representation" if !KUNIT_ALL_TESTS
20 default KUNIT_ALL_TESTS
22 Enable debugfs representation for kunit. Currently this consists
23 of /sys/kernel/debug/kunit/<test_suite>/results files for each
24 test suite, which allow users to see results of the last test suite
27 config KUNIT_FAULT_TEST
28 bool "Enable KUnit tests which print BUG stacktraces"
33 Enables fault handling tests for the KUnit framework. These tests may
34 trigger a kernel BUG(), and the associated stack trace, even when they
35 pass. If this conflicts with your test infrastrcture (or is confusing
36 or annoying), they can be disabled by setting this to N.
39 tristate "KUnit test for KUnit" if !KUNIT_ALL_TESTS
40 default KUNIT_ALL_TESTS
42 Enables the unit tests for the KUnit test framework. These tests test
43 the KUnit test framework itself; the tests are both written using
44 KUnit and test KUnit. This option should only be enabled for testing
45 purposes by developers interested in testing that KUnit works as
48 config KUNIT_EXAMPLE_TEST
49 tristate "Example test for KUnit" if !KUNIT_ALL_TESTS
50 default KUNIT_ALL_TESTS
52 Enables an example unit test that illustrates some of the basic
53 features of KUnit. This test only exists to help new users understand
54 what KUnit is and how it is used. Please refer to the example test
55 itself, lib/kunit/example-test.c, for more information. This option
56 is intended for curious hackers who would like to understand how to
57 use KUnit for kernel development.
59 config KUNIT_ALL_TESTS
60 tristate "All KUnit tests with satisfied dependencies"
62 Enables all KUnit tests, if they can be enabled.
63 KUnit tests run during boot and output the results to the debug log
64 in TAP format (http://testanything.org/). Only useful for kernel devs
65 running the KUnit test harness, and not intended for inclusion into a
68 For more information on KUnit and unit tests in general please refer
69 to the KUnit documentation in Documentation/dev-tools/kunit/.
73 config KUNIT_DEFAULT_ENABLED
74 bool "Default value of kunit.enable"
77 Sets the default value of kunit.enable. If set to N then KUnit
78 tests will not execute unless kunit.enable=1 is passed to the
81 In most cases this should be left as Y. Only if additional opt-in
82 behavior is needed should this be set to N.
