我们可以用场景作为我们度量的一个单元，或者将描述系统行为的每一个步骤作为一个特性。

We might use scenarios as the unit of measure or look at each step that describes system behavior as a feature.

如果您像其他许多程序员一样不喜欢为代码加注，则单元测试是记录代码行为的一种方法。

If you're like many programmers who aren't fond of commenting code, unit tests are a way of documenting your code behavior.

如果没有匹配的odr路由规则，则默认行为是考虑单元中所有拥有匹配请求的URI模式的应用程序。

If there are no ODR routing rules, then the default behavior is to consider all the applications in the cell that have URI patterns which match the request.

So for some you that are less interested in maybe the physical structure of an individual atom, now some more exciting material for you might be coming up if you like to think about how, instead, molecules behave, either within bonding, within themselves, or with other molecules, that's what we're going to be heading to in this next unit.

那么对于某些同学，你们或许不感兴趣,对于单个原子的物理结构，现在可能有令你感到兴奋的内容,要出现了，如果你更喜欢思考,分子的行为，或者是关于成键的，或者是关于它们本身的，又或者与其它分子之间的行为，这些将是我们下个单元要讲的内容。
