* Test cases that share common setup should use the helper

* 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

* Then test case functions can take the form:
|
|
*
|
|
* static int test_foobar_feature()
|
|
* {
|
|
* SETUP_FOOBAR_TEST_FIXTURE();
