c++ 测试篇
作者：CppExplore 网址：http://www.cppblog.com/CppExplore/在c++的世界里，程序设计的优雅让位于程序的稳定性、健壮性。“好程序是测出来的”这句话在C++领域里得到了充分体现。下面是我在开发中使用的测试方法，抛砖引玉，和大家交流下。测试期间，关闭对core文件的限制，使用命令：ulimit -c unlimited
（1）开发阶段，使用cppunit维护测试用例。我一般是用于测试解析类、算法类。
从http://sourceforge.net/projects/cppunit/下载最新版本，解压，看安装文档，一般是./configure & make & make install。
下面举例说明我使用cppunit的方法。假设自己的源码位于src目录下，里面有class1.h/class1.cpp/class2.h/class2.cpp。相对src建立平级目录test存放测试工程，为class1/class2分别建立测试类文件testClass1.h/testClass2.h,建立main函数所在文件test.cpp、makefile。
testClass1.h代码如下,testClass2.h类似。
