| * 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 zero on success or one 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(); |
| * } |
