26 : *
27 : * This file implements various tests that can directly access the internal
28 : * functions of the tld.c, tld_data.c, and tld_domain_to_lowercase.c
29 : * files.
30 : *
31 : * For that purpose we directly include those files in this test. This
32 : * is why the test is not actually linked against the library, it
33 : * includes it within itself.
