使用核心库之外的其他库的应用程序仍然可以实现兼容性，但需要进一步执行回归测试。
An application that USES libraries outside of the core set might still maintain compatibility, but further regression testing should be done.
不过，每个发行版本对核心的定义会稍有不同，这就意味着当宣称您的应用程序支持某个给定的发行版本上时，总是需要进行回归测试。
However, each distribution's definition of core could vary slightly, which means that regression testing is always necessary when claiming your application is supported on a given distribution.
如果你看一下那些测试程序，你会发现它们都是一些针对核心方法的基本测试，主要包括像String
Rubinius was only faster in 2 of 11, and actually error or timeout on 4. If you look at those benchmarks, you’ll see that they are basically tests of a few core methods, mainly things like String#<<.
核心团队可以为在产品发布之前在最终系统测试时的使用而生成系统测试应用程序、场景，和自动脚本的子集。
The core team can produce a subset of the system test applications, scenarios, and automation scripts for use during final system test prior to product release.
这个月，我要把以质量为核心的方法用于Struts应用程序的测试场景。
This month, I walk you through a quality-centered approach to a Struts application testing scenario.
mock让我们能够集中精力测试TeamRoom应用程序的核心功能，而不需要为外部资源操心。
Mocks allow us to concentrate testing on the core functionality in our Team Room application without worrying about inaccessible external resources.
现在这个插件的核心功能已经实现并经过测试，您应该创建一个方便的服务，以一种Grails 友好的方式公开这两个实用程序类。
Now that the plug-in's core functionality is implemented and tested, you should create a convenience service that exposes the two utility classes in a Grails-friendly way.
可以使用fixture指定测试用的数据；mock对象让我们能够集中精力测试应用程序的核心功能，而不必为网络连接或外部系统操心。
Fixtures allow you to specify data for testing, and finally, mock objects let you concentrate on testing the core application without worrying about accessing network connections or external systems.
本测试程序采用框架中多层核心组件编写，演示了操作数据的各种那个功能，以及程序性能。
The test program uses the framework of written multi-core components, shows that feature a variety of operating data, and program performance.
