/*-
|
|
* 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();
|
|
* }
|
