When starting a new application, I usually sketch out (on paper) a really high-level overview of what I think the core models of the app are going to be, and how they relate to one another. Obviously these will likely change as your application evolves during the development process, but it s a good place to start.
然后,从该集合中,我确定应用目标最核心的模式——我首先生成<代码>铁路模型模型Name<>。 例如:我最近正在编写一本旅馆名录,开始采用<条码>Hotel模式。
Then I apply some pretty basic TDD methodologies and start writing the spec for the unit test for that model, run the tests, build, write more spec, refactor, etc. As bits fall into place, do a commit and move on. That way, if you go down a wrong path, it s easy to get back to a healthy spot again and you don t have to worry (as much) about making mistakes.
I usually find that by starting with the unit tests for the core models, the rest of your application will naturally evolve out. Once you decide to move onto functional and integration tests you should have a really clear idea about how all the pieces fit together and how your users should flow through your application. This should naturally lead you to develop controllers that fit your different user s scenarios.
最重要的是,实践是从零开始的最佳途径。 形成一些具有真正明确结果的基本数据,如博客或简单的时间安排工具。 当你转向更大规模或更抽象的用途时,它将帮助你利用这一进程——你更善于脱离实地。
