     66  * SETUP_TEST_FIXTURE and EXECUTE_TEST macros for test case functions.
     67  *
     68  * SETUP_TEST_FIXTURE will call set_up() to create a new TEST_FIXTURE_TYPE
     69  * object called "fixture". It will also allocate the "result" variable used
     70  * by EXECUTE_TEST. set_up() should take a const char* specifying the test
     71  * case name and return a TEST_FIXTURE_TYPE by reference.

     76  * take a TEST_FIXTURE_TYPE by reference and return 1 on success and 0 on
     77  * failure.  The tear_down function is responsible for deallocation of the
     78  * result variable, if required.
     79  *
     80  * Unit tests can define their own SETUP_TEST_FIXTURE and EXECUTE_TEST

     87  *   EXECUTE_TEST(execute_foobar, tear_down_foobar)
     88  *

     90  *
     91  * static int test_foobar_feature()
     92  *      {
