接口驱动，点点实践中。
要做的事情高人们已给规划出来了，你只要去实现他就OK了。 以一个菜鸟的眼光看，确实不错！ |

chenk85 写道 再好的设计也是重构得到的，如果一开始就放入大量的设计模式，那这个设计是过度设计。既然是用TDD，那一开始的代码或许就是没什么设计技巧的代码，通过持续的重构，代码的设计才能变得漂亮起来。坚持用TDD就不存在楼上的同学讲的情况，因为不会过度设计。
好像还是不明白楼主对CTO的工作的看法。 过渡设计不好，不过我们不需要为了展示一下重构，就“那一开始的代码或许就是没什么设计技巧的代码”？ |

看了評論，感覺自己做外包（coding）看來是沒有前途了！

哎，做了几个项目后，发现自我的设计水平都很差，所以现在一般都在看设计方面的资料，以前以为会代码开发就很牛了，现在发现自己还太差，学习楼上的设计，一直比较喜欢TDD（测试驱动开发）无耐一写就乱了，真该好好补补课了

SunMicro 写道 在项目中也一直在尝试Interface design和测试驱动，不过有时候会有一种立即实现的冲动，特别是在对一些接口设计感觉不自信的情况下，希望通过具体实现来验证，然后不知不觉就又陷入了细节考究之只中。
同感,可能还是技术不到家吧,对自己没有信心,还是需要多接触些项目,累计经验才能出现好的Interface design.

真他妈的同感！不知道如何解决这个坏习惯。 |

是的,CTO是不会干这种事情的.CTO是在整个公司的技术发展方向上作引导,更多关心业界的动向和公司的发展.
只能说CTO曾经是干过这些的. |

我不觉得， 其实我们的水平也就是干干苦力的料，搞什么设计呵呵，邯郸学步罢了。 应该说你没见过牛人,所以不要把这些人也包含进去 |

老外程序员牛人有，鸟人水平也就那样，你自己看看apache那些开源项目中的代码
乱七八糟的多的是，没有必要妄自菲薄 JavaVision 写道 chenk85 写道 再好的设计也是重构得到的，如果一开始就放入大量的设计模式，那这个设计是过度设计。既然是用TDD，那一开始的代码或许就是没什么设计技巧的代码，通过持续的重构，代码的设计才能变得漂亮起来。坚持用TDD就不存在楼上的同学讲的情况，因为不会过度设计。
