ARRAY_SIZE already checks for you that it's a real array via __must_be_array(). The other question is, will kunit_param_generator_helper() find much use without the KUNIT_PARAM_GENERATOR_HELPER() macro? If I have some complicated generator protocol to generate params, then I'd just directly write the generator function. If your intent is to simplify the common-case array based generators, why not just have a macro generate the generator function? More specifically, have this macro here: +#define KUNIT_ARRAY_PARAM(name, array) \ + static void *name##_gen_params(struct kunit *test, void *prev) \ + { \ + typeof((array)[0]) *__next = prev ? ((typeof(__next)) prev) + 1 : (array); \ + return __next - (array) < ARRAY_SIZE((array)) ? __next : NULL; \ + } [ It is entirely untested, but if it works verbatim you'll probably need my Co-developed-by: Marco Elver <elver@google.com> Signed-off-by: Marco Elver <elver@google.com> just in case... ] Then, it can be used as follows: static int num_cpus[] = {1, 2, 3, 4, 5}; KUNIT_ARRAY_PARAM(num_cpus, num_cpus); Then somewhere else: KUNIT_CASE_PARAM(some_test, num_cpus_gen_params); > #endif /* _KUNIT_TEST_H */ > diff --git a/lib/kunit/test.c b/lib/kunit/test.c > index 750704abe89a..0e6ffe6384a7 100644 > --- a/lib/kunit/test.c > +++ b/lib/kunit/test.c > @@ -127,6 +127,11 @@ unsigned int kunit_test_case_num(struct kunit_suite *suite, > } > EXPORT_SYMBOL_GPL(kunit_test_case_num); > > +static void kunit_print_failed_param(struct kunit *test) > +{ > + kunit_err(test, "\n\tTest failed at parameter: %d\n", test->current_param + 1); > +} > + > static void kunit_print_string_stream(struct kunit *test, > struct string_stream *stream) > { > @@ -168,6 +173,8 @@ static void kunit_fail(struct kunit *test, struct kunit_assert *assert) > assert->format(assert, stream); > > kunit_print_string_stream(test, stream); > + if (test->param_values) > + kunit_print_failed_param(test); > > WARN_ON(string_stream_destroy(stream)); > } > @@ -239,7 +246,18 @@ static void kunit_run_case_internal(struct kunit *test, > } > } > > - test_case->run_case(test); > + if (!test_case->generate_params) { > + test_case->run_case(test); > + } else { > + test->param_values = test_case->generate_params(test, NULL); > + test->current_param = 0; > + > + while (test->param_values) { > + test_case->run_case(test); > + test->param_values = test_case->generate_params(test, test->param_values); > + test->current_param++; > + } > + } > } > > static void kunit_case_internal_cleanup(struct kunit *test) Otherwise looks fine.

Ah sorry, it's in a header so we might get complaints if it's not inline. But in any case, if you use the KUNIT_ARRAY_PARAM() macro I proposed, this function will become obsolete. Thanks, -- Marco
