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/. 15 16if KUNIT 17 18config KUNIT_DEBUGFS 19 bool "KUnit - Enable /sys/kernel/debug/kunit debugfs representation" if !KUNIT_ALL_TESTS 20 default KUNIT_ALL_TESTS 21 help 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 25 run that occurred. 26 27config KUNIT_TEST 28 tristate "KUnit test for KUnit" if !KUNIT_ALL_TESTS 29 default KUNIT_ALL_TESTS 30 help 31 Enables the unit tests for the KUnit test framework. These tests test 32 the KUnit test framework itself; the tests are both written using 33 KUnit and test KUnit. This option should only be enabled for testing 34 purposes by developers interested in testing that KUnit works as 35 expected. 36 37config KUNIT_EXAMPLE_TEST 38 tristate "Example test for KUnit" if !KUNIT_ALL_TESTS 39 default KUNIT_ALL_TESTS 40 help 41 Enables an example unit test that illustrates some of the basic 42 features of KUnit. This test only exists to help new users understand 43 what KUnit is and how it is used. Please refer to the example test 44 itself, lib/kunit/example-test.c, for more information. This option 45 is intended for curious hackers who would like to understand how to 46 use KUnit for kernel development. 47 48config KUNIT_ALL_TESTS 49 tristate "All KUnit tests with satisfied dependencies" 50 help 51 Enables all KUnit tests, if they can be enabled. 52 KUnit tests run during boot and output the results to the debug log 53 in TAP format (http://testanything.org/). Only useful for kernel devs 54 running the KUnit test harness, and not intended for inclusion into a 55 production build. 56 57 For more information on KUnit and unit tests in general please refer 58 to the KUnit documentation in Documentation/dev-tools/kunit/. 59 60 If unsure, say N. 61 62config KUNIT_DEFAULT_ENABLED 63 bool "Default value of kunit.enable" 64 default y 65 help 66 Sets the default value of kunit.enable. If set to N then KUnit 67 tests will not execute unless kunit.enable=1 is passed to the 68 kernel command line. 69 70 In most cases this should be left as Y. Only if additional opt-in 71 behavior is needed should this be set to N. 72 73endif # KUNIT 74
