linux-kselftest-kunit-5.12-rc1
This KUnit update for Linux 5.12-rc1 consists of consists of:
-- support for filtering test suites using glob from Daniel Latypov.
"kunit_filter.glob" command line option is passed to the UML
kernel, which currently only supports filtering by suite name.
This support allows running different subsets of tests, e.g.
$ ./tools/testing/kunit/kunit.py build
$ ./tools/testing/kunit/kunit.py exec 'list*'
$ ./tools/testing/kunit/kunit.py exec 'kunit*'
-- several fixes and cleanups also from Daniel Latypov.

Pull KUnit updates from Shuah Khan
- support for filtering test suites using glob from Daniel Latypov.
"kunit_filter.glob" command line option is passed to the UML
kernel, which currently only supports filtering by suite name.
This support allows running different subsets of tests, e.g.
$ ./tools/testing/kunit/kunit.py build
$ ./tools/testing/kunit/kunit.py exec 'list*'
$ ./tools/testing/kunit/kunit.py exec 'kunit*'
- several fixes and cleanups also from Daniel Latypov.
* tag 'linux-kselftest-kunit-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest:
kunit: tool: fix unintentional statefulness in run_kernel()
kunit: tool: add support for filtering suites by glob
kunit: add kunit.filter_glob cmdline option to filter suites

kunit: make kunit_tool accept optional path to .kunitconfig fragment
Documentation: kunit: add tips.rst for small examples

============================
|
||||
Tips For Writing KUnit Tests
|
||||
============================
|
||||
|
||||
Exiting early on failed expectations
|
||||
------------------------------------
|
||||
|
||||
``KUNIT_EXPECT_EQ`` and friends will mark the test as failed and continue
|
||||
execution. In some cases, it's unsafe to continue and you can use the
|
||||
``KUNIT_ASSERT`` variant to exit on failure.
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
void example_test_user_alloc_function(struct kunit *test)
|
||||
{
|
||||
void *object = alloc_some_object_for_me();
|
||||
|
||||
/* Make sure we got a valid pointer back. */
|
||||
KUNIT_ASSERT_NOT_ERR_OR_NULL(test, object);
|
||||
do_something_with_object(object);
|
||||
}
|
||||
|
||||
Allocating memory
|
||||
-----------------
|
||||
|
||||
Where you would use ``kzalloc``, you should prefer ``kunit_kzalloc`` instead.
|
||||
KUnit will ensure the memory is freed once the test completes.
|
||||
|
||||
This is particularly useful since it lets you use the ``KUNIT_ASSERT_EQ``
|
||||
macros to exit early from a test without having to worry about remembering to
|
||||
call ``kfree``.
|
||||
|
||||
Example:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
void example_test_allocation(struct kunit *test)
|
||||
{
|
||||
char *buffer = kunit_kzalloc(test, 16, GFP_KERNEL);
|
||||
/* Ensure allocation succeeded. */
|
||||
KUNIT_ASSERT_NOT_ERR_OR_NULL(test, buffer);
|
||||
|
||||
KUNIT_ASSERT_STREQ(test, buffer, "");
|
||||
}
|
||||
|
||||
|
||||
Testing static functions
|
||||
------------------------
|
||||
|
||||
If you don't want to expose functions or variables just for testing, one option
|
||||
is to conditionally ``#include`` the test file at the end of your .c file, e.g.
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* In my_file.c */
|
||||
|
||||
static int do_interesting_thing();
|
||||
|
||||
#ifdef CONFIG_MY_KUNIT_TEST
|
||||
#include "my_kunit_test.c"
|
||||
#endif
|
||||
|
||||
Injecting test-only code
|
||||
------------------------
|
||||
|
||||
Similarly to the above, it can be useful to add test-specific logic.
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* In my_file.h */
|
||||
|
||||
#ifdef CONFIG_MY_KUNIT_TEST
|
||||
/* Defined in my_kunit_test.c */
|
||||
void test_only_hook(void);
|
||||
#else
|
||||
void test_only_hook(void) { }
|
||||
#endif
|
||||
|
||||
TODO(dlatypov@google.com): add an example of using ``current->kunit_test`` in
|
||||
such a hook when it's not only updated for ``CONFIG_KASAN=y``.
|
||||
|
||||
Customizing error messages
|
||||
--------------------------
|
||||
|
||||
Each of the ``KUNIT_EXPECT`` and ``KUNIT_ASSERT`` macros have a ``_MSG`` variant.
|
||||
These take a format string and arguments to provide additional context to the automatically generated error messages.
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
char some_str[41];
|
||||
generate_sha1_hex_string(some_str);
|
||||
|
||||
/* Before. Not easy to tell why the test failed. */
|
||||
KUNIT_EXPECT_EQ(test, strlen(some_str), 40);
|
||||
|
||||
/* After. Now we see the offending string. */
|
||||
KUNIT_EXPECT_EQ_MSG(test, strlen(some_str), 40, "some_str='%s'", some_str);
|
||||
|
||||
Alternatively, one can take full control over the error message by using ``KUNIT_FAIL()``, e.g.
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* Before */
|
||||
KUNIT_EXPECT_EQ(test, some_setup_function(), 0);
|
||||
|
||||
/* After: full control over the failure message. */
|
||||
if (some_setup_function())
|
||||
KUNIT_FAIL(test, "Failed to setup thing for testing");
|
||||

||||
