【实例简介】个人编程中比较喜欢重构，重构能够提高自己的代码质量，使代码阅读起来也更清晰。但是重构有一个问题，就是如何保证重构后带代码实现的功能与重构前的一致，如果每次重构完成后，对此不闻不问，则会有极大的风险，如果每次重构后，都进行一边测试，则工作量会很巨大，最终可能是即使代码有重构的欲望，也会尽量克制住，不去重构。除非代码能够进行自动化测试。实际上进行测试的是接口，而不是所有代码，只要能够保持接口不变，自动化测试的工作量也没有想象中的巨大。其实我们在单元测试的时候，会测试各种异常情况，只不过，没有将这些测试写成测试代码罢了。 在Java中有JUnit，在C#中有NUnit，在C++中，笔者并不知道有哪些自动化测试工具（笔者的孤陋寡闻）。于是就产生了自己写一个自动化测试程序的想法。

【实例简介】电动汽车燃料电池仿真模型，本模型是基于matlab中simulink工具箱建立的，用于在环仿真（无法运行，只是个模型）

vc6操作数据库，从数据库到listbox读写数据。自己的测试代码，保证能用。

【实例简介】基于STM32的主控板，包含原理图和PCB，还有一些元器件的封装，下载后可以直接使用，可以打板，没有任何问题。
