/* 
 * File:   test.h
 * Author: Mike
 *
 * Created on 18. Februar 2012, 14:15

 *
 *
 * Usage of this test framework:
 *
 * **** IN HEADER FILE: ****
 *
 * UCX_TEST_DECLARE(function_name)
 *
 * **** IN SOURCE FILE: ****
 *
 * UCX_TEST_IMPLEMENT(function_name) {
 *  <memory allocation and other stuff here>
 *  UCX_TEST_BEGIN
 *  <tests with UCX_TEST_ASSERT here>
 *  UCX_TEST_END
 *  <cleanup of memory here>
 * }
 *
 * PLEASE NOTE: if a test fails, a longjump is performed
 * back to the UCX_TEST_BEGIN macro!
 *
 * You may use multiple BEGIN-END blocks if you are aware of the
 * longjmp behaviour.
 *
