/* This tests the API presented by the libopus system.
   It does not attempt to extensively exercise the codec internals.
   The strategy here is to simply the API interface invariants:
   That sane options are accepted, insane options are rejected,
   and that nothing blows up. In particular we don't actually test
   that settings are heeded by the codec (though we do check that
   get after set returns a sane value when it should). Other
   tests check the actual codec behavior.
   In cases where its reasonable to do so we test exhaustively,
   but its not reasonable to do so in all cases.
   Although these tests are simple they found several library bugs
   when they were initially developed. */

/* These tests are more sensitive if compiled with -DVALGRIND and
   run inside valgrind. Malloc failure testing requires glibc. */
