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...]
