Take a look at igt_kselftests():

        igt_subtest_with_dynamic(filter ?: "all-tests") {
                igt_list_for_each_entry_safe(tl, tn, &tests, link) {
                        unsigned long taints;

                        igt_dynamic_f("%s", unfilter(filter, tl->name))
                                igt_kselftest_execute(&tst, tl, options, result);
                        free(tl);

The default when "filter" is not used is "all-tests".
