TDD开发的感觉

1.类的结构更加松散了,

2.类本身也变得更小,名称利于理解.

3.最重要的是获得了一种新的视角,可以从外到内的驱动程序的开发.不知不觉间有了一种很明确的目标感,知道自己在干什么.而且精力就集中在这个点上这个感觉实在是好.这个类似于上帝的视角.

4.目前我用接口将所有的外部依赖解耦和掉.这样做就像自己本身获得了自由一样.代码可以到处的移植.更换皮肤,更换数据库soeasy.

5.更好的可维护性.发现断点调试用的越来越少了.

6.目前的开发方式转换为先用测试数据和Monk搭建一个程序骨架,然后再填充里面的细节.

7.试试由外到内将一个巨类分解为可以测试的小类.瞄定输入输出就可以开干了.试试效果.

一开始是这个样子的记录一下.
