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 16 if KUNIT 17 18 config 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 27 config KUNIT_FAULT_TEST 28 bool "Enable KUnit tests which print BUG stacktraces" 29 depends on KUNIT_TEST 30 depends on !UML 31 default y 32 help 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. 37 38 config KUNIT_TEST 39 tristate "KUnit test for KUnit" if !KUNIT_ALL_TESTS 40 default KUNIT_ALL_TESTS 41 help 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 46 expected. 47 48 config KUNIT_EXAMPLE_TEST 49 tristate "Example test for KUnit" if !KUNIT_ALL_TESTS 50 default KUNIT_ALL_TESTS 51 help 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. 58 59 config KUNIT_ALL_TESTS 60 tristate "All KUnit tests with satisfied dependencies" 61 help 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 66 production build. 67 68 For more information on KUnit and unit tests in general please refer 69 to the KUnit documentation in Documentation/dev-tools/kunit/. 70 71 If unsure, say N. 72 73 config KUNIT_DEFAULT_ENABLED 74 bool "Default value of kunit.enable" 75 default y 76 help 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 79 kernel command line. 80 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. 83 84 endif # KUNIT
