/* Usage:
|
|
1. Call UT_DECLARE(), define some global variables;
|
|
2. Define an array of ut_case_t, for example:
|
|
static ut_case_t gs_ut_case[] = {
|
|
{"test case1 name", NULL, ut_test_case1, NULL},
|
|
{"test case2 name", NULL, ut_test_case2, NULL},
|
|
};
|
|
3. Call UT_RUN(gs_ut_case), gs_ut_case is defined in 2.
|
|
4. Call UT_END(), display the statistics result.
