如果可以使用xml语法来生成一组初始的类和相应的绑定定义，那么其优点就是可以快速地获取工作代码。

If an XML grammar could be used for generating an initial set of classes and a corresponding binding definition, this would provide the benefit of getting working code quickly.

您可以通过它们精确地定义有较广影响而在目标类中有较少语法残留的行为。

They allow you to concisely define behavior that has wide-ranging impact with very little syntactic hangover in the target class.

下一步就是运行您的单元测试，修正语法错误(即，编写一个类，使它实现您的测试刚定义的接口)，并再次运行测试。

The next step is to run your unit tests, fix the syntax errors (that is, implement the class with the interfaces just defined by your test), and run the tests again.
