We write **unit tests** to explore and confirm the **behavior** of parts of our application.
我们编写**单元测试**来探索并巩固应用程序中的**行为**部分。
1. They **guard** against breaking existing code (“regressions”) when we make changes.
1. 当我们做出修改时,它们会**守护**已有代码(回归测试),防止其被破坏。
1. They **clarify** what the code does both when used as intended and when faced with deviant conditions.
1. 当我们正确使用代码和面对异常情况时,它们会让代码的用途更加**明晰**。
1. They **reveal** mistakes in design and implementation. Tests force us to look at our code from many angles. When a part of our application seems hard to test, we may have discovered a design flaw, something we can cure now rather than later when it becomes expensive to fix.
1. 它们会**揭露**我们设计和实现中的错误。测试会强迫我们从多种角度看代码。如果应用程序的一个部分看起来很难测试,这可能就意味着存在设计缺陷。
我们可以立即修复它,而不用等到它变得不可收拾的那一天。
