E.g. specifying this would run suites with "list" in their name. kunit.filter_glob=list* Note: the executor prints out a TAP header that includes the number of suites we intend to run. So unless we want to report empty results for filtered-out suites, we need to do the filtering here in the executor. It's also probably better in the executor since we most likely don't want any filtering to apply to tests built as modules. This code does add a CONFIG_GLOB=y dependency for CONFIG_KUNIT=y. But the code seems light enough that it shouldn't be an issue. For now, we only filter on suite names so we don't have to create copies of the suites themselves, just the array (of arrays) holding them. The name is rather generic since in the future, we could consider extending it to a syntax like: kunit.filter_glob=<suite_glob>.<test_glob> E.g. to run all the del list tests kunit.filter_glob=list-kunit-test.*del* But at the moment, it's far easier to manually comment out test cases in test files as opposed to messing with sets of Kconfig entries to select specific suites. So even just doing this makes using kunit far less annoying.

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

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

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

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.

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.
