这个简单的类让我们可以开发GUI；在开发显示逻辑之后，只需经过简单的修改，就可以用真正的JSON服务测试GUI。
This simple class lets you develop the GUI and later, with slight modification, test the GUI with the real JSON service after you develop the display logic.
因此，当需要重新命名一个方法或者类的时候，开发环境很容易通过在AST 中精确定位找到方法或类被引用的每个地方。
So when you want to rename a method or class, it's easy for the environment to find every use of it by pinpointing the location in the AST.
注意：这些类中的所有方法都是静态的，所以测试开发人员不需要将这个类实例化为一个对象就可以使用这些方法。
Note: All methods in these classes are static, so the test developer does not need to instantiate an object of this type to use them.
要想这样做，开发人员需要手动地实现所提供的接口，并且扩展抽象基础类。
To do so, developers would need to manually implement the provided interfaces and extend the abstract base classes.
将应用程序翻译成其他语言，而不是开发人员在开发期间使用的语言，这需要对此软件进行三类测试。
Translating the application to languages that are not the language used by developers during development adds the necessity for three types of tests to be done on the software.
除了类的对象实例之外，这样做还可以让您避免构建和操作类的开发、部署和执行成本。
This lets you avoid the development, deployment, and execution costs of building and manipulating classes in addition to the object instances of those classes.
MDAT可以生成这些类的框架代码，但由开发人员提供特定的实现。
MDAT can generate skeleton code for these classes, but the specific implementation is provided by the developer.
测试类表示在开发时发生的测试执行的常见单元，所以我们应仔细考虑任何一个类中包括了多少个测试。
The test class represents the usual unit of test execution that occurs while you are developing, and so we should consider carefully how many tests to include in any one class.
