- * The unit test implementation MUST provide list of unit tests it implements

- * a function implementing it. The function does not take any arguments
- * and has no return values, i.e. every test function has to be compatible
- * with this prototype:

-/* These macros are the same as TEST_CHECK_ and TEST_CHECK except that if the

- *
- * That is done either by calling abort() if the unit test is executed as a
- * child process; or via longjmp() if the unit test is executed within the
- * main Acutest process.
- *
- * As a side effect of such abortion, your unit tests may cause memory leaks,
- * unflushed file descriptors, and other phenomena caused by the abortion.
- *
- * Therefore you should not use these as a general replacement for TEST_CHECK.
