  64  * Test cases that share common setup should use the helper
  65  * SETUP_TEST_FIXTURE and EXECUTE_TEST macros for test case functions.
  66  *
  67  * SETUP_TEST_FIXTURE will call set_up() to create a new TEST_FIXTURE_TYPE
  68  * object called "fixture". It will also allocate the "result" variable used
  69  * by EXECUTE_TEST. set_up() should take a const char* specifying the test
  70  * case name and return a TEST_FIXTURE_TYPE by reference.
  71  * If case set_up() fails then 0 is returned.
  72  *
  73  * EXECUTE_TEST will pass fixture to execute_func() by reference, call
  74  * tear_down(), and return the result of execute_func(). execute_func() should
  75  * take a TEST_FIXTURE_TYPE by reference and return 1 on success and 0 on
  76  * failure.  The tear_down function is responsible for deallocation of the
  77  * result variable, if required.
  78  *
  79  * Unit tests can define their own SETUP_TEST_FIXTURE and EXECUTE_TEST
  80  * variations like so:
  81  *
  82  * #define SETUP_FOOBAR_TEST_FIXTURE()\
  83  *   SETUP_TEST_FIXTURE(FOOBAR_TEST_FIXTURE, set_up_foobar)
  84  *
  85  * #define EXECUTE_FOOBAR_TEST()\
  86  *   EXECUTE_TEST(execute_foobar, tear_down_foobar)
  87  *
  88  * Then test case functions can take the form:
  89  *
  90  * static int test_foobar_feature()
  91  *      {
  92  *      SETUP_FOOBAR_TEST_FIXTURE();
  93  *      [...set individual members of fixture...]
