单元测试3
看了《Think in C++ Volume 2》第2章中Cppunit基本框架之后，想起自己之前总结的“ 单元测试2”，便将源码拿过来扩展一下，再次体会了Cppunit的基本思想。（有空继续扩展）
同时，阅读《How Google Test Software》时，里面的一句话让我反思软件测试的意义。
Quality is not equal to test. Quality is achieved by putting development and testing into a blender and mixing them until one is indistinguishable from the other.

软件质量不等于测试；软件质量是通过将开发和测试混为一体，直到无法区分彼此。
