这是非常重要的，因为它提供了只部署发生修改的子集（如，用于单元测试），而无需部署整个应用程序的能力。
This is important since it allows the capability to deploy only the modified subset (i.e. for unit testing) or the whole application.
使用ConTest可以使它在单元测试中发生。
想象一下，Web客户端上单元格的值在你眼前发生变化，还会简单地改变颜色以提醒你有变更。
Imagine a web client where the cell values change in front of your eyes, and change color briefly to alert you to the change.
没有了这层保护膜，正如单元测试集合(test suite)所说，什么事情都有可能发生。
Without that protection, anything may happen-as is demonstrated by the unit test suite.
当某个事务（COMMIT或ROLLBACK）发生或在工作单元 (UOW)结束时
When a transaction (COMMIT or ROLLBACK) occurs or at the end of a unit-of-work (UOW)
单元测试是把同时发生的LotusScript事件的数目降至最低的另一种好方法。
Unit testing is another good approach for minimizing the number of simultaneous LotusScript events.
单元测试意味着在隔离环境中运行，所以不会运行数据库和Web服务器，最重要的是不会发生与Grails 相关的元编程。
Unit tests are meant to run in isolation, which means that no database is running, no Web server is running, and — most important — no Grails-related metaprogramming occurs.
您可以通过保证范围（每个投影长度单元对应多少像素）在x和y方向上相同（或接近）来防止这种情况发生。
You can prevent this by making sure the scale (how many pixels correspond to each projected unit of distance) is the same (or close) in both the x and y directions.
通过这种方式，如果出现错误(这种情况不会发生，因为您编写了非常出色的单元测试，不是吗？)，就可以查看重构历史记录，看看发生了什么。
That way, if something breaks (which it won't because you're writing really good unit tests, right?), you can look at the refactoring history and see what happened.
在运行高可用性站点时，您必须假设某一天单元内会发生一起灾难性事件。
When running a highly available site, you must assume that a catastrophic incident will occur one day in a cell.
软件开发生命周期的设计和编码阶段，为单元测试的质量检验关提供了一个机会。
The design and coding phase of your software development lifecycle offers an opportunity for a quality gate designed around unit testing.

Empty table cells indicate events that should not occur in particular states.
由于配置已发生更改，因此计算单元中的所有联合节点都需要下载新的配置。
Since the configuration has been changed, all federated nodes in the cell need to download the new configuration.
测试服务提供支持单元测试的能力和作为总体开发生命周期的一部分的集成测试功能。
Test services provide the ability to support unit test as well as integrated test capabilities as part of the overall development lifecycle.
特定的单元可能经常发生故障，但是在应用程序级别出现的唯一结果是在整体性能方面的各种怪异变化。
A particular unit might fail frequently, but the only consequence apparent at the application level is spooky variations in over-all performance.

Each cell in the table specifies the actions the widget will take when a particular event occurs in a particular state.
在短期运行流程中，调用的服务被绑定到一起，就像一个工作单元一样；故障发生时，事务性服务能够回滚。
In a short-running process, the services invoked are committed together as one unit of work; in the case of a failure, transactional services can roll-back.
