标题

第一段

Despite your best efforts to pin your customers to the ground and extract exact requirements from them on pain of horrible nasty things involving scissors and hot wax, requirements will change. Most customers don't know what they want until they see it, and even if they do, they aren't that good at articulating what they want precisely enough to be useful. And even if they do, they'll want more in the next release anyway. So be prepared to update your test cases as requirements change.
尽管你竭尽努力地分析你的客户需求，并点灯熬油地提炼出相应^精确的要^需求，但要求是^{需求还是会}变化的。大部分客户在看到产品前不知道他们要^想要什么。即便知道，也不能很好地^善于精确表述出他们的有效需求。即便能表述出来，他们下一次^{在下一个版本}一定要^会要求更多的功能。因此你需要让你的独立测试做好更新准备^{做好更新测试用例的准备}以应对要求^需求的改变。

第2段

Suppose, for instance, that you wanted to expand the range of the Roman numeral conversion functions. Remember the rule that said that no character could be repeated more than three times? Well, the Romans were willing to make an exception to that rule by having 4 M characters in a row to represent 4000. If you make this change, you'll be able to expand the range of convertible numbers from 1..3999 to 1..4999. But first, you need to make some changes to the test cases.
假设你想要扩展罗马数字转换 ^函数的范围。记住这条原则：没有哪个字符可以重复三遍以上 ^{还记得“没有哪个字符可以重复三遍以上”这条规则吗}？啊哈！罗马数字可以连续出现 4 次M 字符来表示 4000 便是一个例外^{呃，现在罗马人希望给这条规则来个例外，用连续出现 4 个M 字符来表示 4000}。如果你做出这个改变^这样改了，你则^就可以把转换范围从 1..3999 扩展到 1..4999。但首先，你先要对独立测试^测试用例进行修改。
