Bugs come in three basic varieties: coding bugs, documentation bugs, and requirement bugs.

有三种基本类型的错误：编码错误、文档错误和需求错误。

Unfortunately requirement and documentation bugs are outside the scope of what we can do here, so we'll have to limit ourselves to "detecting," "solving," and "fixing" coding bugs.

不幸的是，需求错误和文档错误不在本文范围之内，因此，我们只好只讨论如何“检测”、“解决”和“修复”编码错误了。

I also have documentation, describing the behavior of the system, and a good start at a test suite. Each test case backs up a fundamental requirement in the system.

我还具备一个描述系统行为的文档，这是进行一系列测试的好起点。
