* SETUP_TEST_FIXTURE and EXECUTE_TEST macros for test case functions.
*
* SETUP_TEST_FIXTURE will call set_up() to create a new TEST_FIXTURE_TYPE
* object called "fixture". It will also allocate the "result" variable used
* by EXECUTE_TEST. set_up() should take a const char* specifying the test
* case name and return a TEST_FIXTURE_TYPE by value.
*
* EXECUTE_TEST will pass fixture to execute_func() by value, call
* tear_down(), and return the result of execute_func(). execute_func() should
* take a TEST_FIXTURE_TYPE by value and return 1 on success and 0 on
* failure.
*
* Unit tests can define their own SETUP_TEST_FIXTURE and EXECUTE_TEST
* variations like so:
*
* #define SETUP_FOOBAR_TEST_FIXTURE()\
* SETUP_TEST_FIXTURE(FOOBAR_TEST_FIXTURE, set_up_foobar)
*
* #define EXECUTE_FOOBAR_TEST()\
* EXECUTE_TEST(execute_foobar, tear_down_foobar)
*
* Then test case functions can take the form:
*
* static int test_foobar_feature()
* {
* SETUP_FOOBAR_TEST_FIXTURE();
* [...set individual members of fixture...]
* EXECUTE_FOOBAR_TEST();
* }
