首先在应用程序的目录里的其中一个模块做.

这里我们假设在frontend里

1 mkdir frontend/config/error

2 cd

关于功能测试的总结

编码之前写好功能测试目前来看不太容易实现,很多细节都是编码之前很难考虑到的,而且如果没有实际功能存在也没有办法对测试进行测试。

功能测试感觉上应该更适合一边编码一边写比较好,这样主要是保证后期修改不对当前功能产生不良影响。

而类似分页这种比较复杂的东西我觉得应该放在单元测试中。

提前写测试应该比较适合单元测试,比如为了实现功能提出在Peer中增加某个方法,那么输入输出都是固定的,全套测试也比较好实现。

Arch Linux安装记录(1) – 安装系统
