65  * Test cases that share common setup should use the helper
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.
72  * If case set_up() fails then 0 is returned.
73  *
74  * EXECUTE_TEST will pass fixture to execute_func() by reference, call
75  * tear_down(), and return the result of execute_func(). execute_func() should
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
81  * variations like so:
82  *
83  * #define SETUP_FOOBAR_TEST_FIXTURE()\
84  *   SETUP_TEST_FIXTURE(FOOBAR_TEST_FIXTURE, set_up_foobar)
85  *
86  * #define EXECUTE_FOOBAR_TEST()\
87  *   EXECUTE_TEST(execute_foobar, tear_down_foobar)
88  *
89  * Then test case functions can take the form:
90  *
91  * static int test_foobar_feature()
92  *      {
93  *      SETUP_FOOBAR_TEST_FIXTURE();
94  *      [...set individual members of fixture...]
