一个简单地C++ Unit Test framework

一 使用

定义一个测试类，在这个类中使用下列宏来申明test case:

DECLARE_AS_TESTER                //申明一个类为tester，需要放在开头［必有］

DECLARE_SETUP                        //申明一个setup方法［可选］

DECLARE_TEARDOWN                //申明一个teardown方法用于清理工作［可选］

DECLARE_TEST(testName)          //申明一个test［至少有一个，否则没意义］

3.  实现定义的setup，teardown，和test方法;

4.  调用宏CALL_TEST注册这个unit test:

5.  在主程序中定义一个TestMain，然后调用它的run方法:

using namespace FTest;

TestMain myTest(std::cout);

myTest.run();

对IntWraper的完整的test 代码如下:
