我希望你们能够发现在单元测试中使用模拟对象的益处，也希望这篇简短的指南能够帮您了解如何简单地创建模拟对象。

I hope that you see the benefits of using mock objects in unit testing. I also hope this brief tutorial helps you see how to create mock objects easily.

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。

I'm not going to talk about them in detail but please look at that to remind yourself of those kinds of specialized sub-cellular units which are present in cells in humans but not present in bacteria.

我就不再赘述了,不过请你们看看书,回忆一下哪些特化的亚细胞结构单元,是人类细胞有,而细菌没有的
