Refactoring and Design的意思|示意

In this installment, I started the discussion about using refactoring as a tool to help understand and identify emergent design.

在本期文章中，我首先讨论了使用重构作为手段来帮助理解和识别紧急设计。

Bill Venners: in your book, Refactoring you say, "the code says everything once and only once, which is the essence of good design."

比尔：你在《重构》一书中提到：“代码应该实现任何逻辑一次且仅一次，这是良好设计的要素”。

The truth is that in order to perform refactoring successfully, you should have full understanding of the problem domain, be aware of requirements, the design and even implementation details.

事实上，为了成功地执行重构，你需要完整地理解整个问题域，了解需求、设计甚至实现阶段的细节。

The discussion also includes topics like evolutionary design, architecture refactoring and how to analyze, test and validate the architecture models.

这次采访还谈到了演化设计、架构重构以及如何对架构模型进行分析、测试和验证相关的话题。

People with good core qualities will pick up the best approaches including writing unit tests and refactoring; learn design patterns and what is most important -deliver great and useful software.

拥有优秀核心品质的人会提出最优的方法，包括编写单元测试和重构；学习设计模式，并且最重要的是：开发出众并实用的软件。

The innermost level consisted of lower level practices such as pair programming; coding standards; unit and function testing; refactoring; simple design; and the 40-hour week.

最内层的级别包括比较底层的实践，比如结对编程、编码标准、单元测试和功能测试、重构、简单设计，以及每周工作40小时。
