Important lesson, so that there would be some predictability in the results and I would have some, if you will, smoke test for knowing whether or not I was getting, my code seemed to be working.

这很重要，因为这样我就可以预测,结果会是多少了，如果你愿意，我们可以做烟气试验,来看我的代码是否工作正常。

First one, when I write a piece of code, especially code that has branches in it, when I design test cases for that piece of code, I should try and have a specific test case for each possible path through the code.

第一点，当我们写代码的时候，尤其是一些含有分支语句的代码的时候，当我为这些代码,设计测试用例的时候，我应该为每一个可能的程序路径,都设计一个特别的用例。

OK.Let's look at the code-- actually, let's test this out first before we do it.

因此我已经添加了，就像Guttag教授做的那样-啊，应该这么说。
