  Cleanup the testing toolkit Tests are now declared with detailed descriptions and a short test name: BEGIN_TEST(the_test0, "this is an example test that does something") ... END_TEST Modules are declared through a simple macro interface: BEGIN_MODULE(mod_name) ADD_TEST(the_test0); ... END_MODULE Error messages when tests fail have been greatly improved.
