TDD第一原则

这些是我关于FIRST原则的笔记：

• Fast: run (subset of) tests quickly (since you’ll be running them all the time)
• Independent: no tests depend on others,so can run any subset in any order
• Repeatable: run N times,get same result (to help isolate bugs and enable automation)
• Self-checking: test can automatically detect if passed (no human checking of output)
• Timely: written about the same time as code under test (with TDD,written first!)

测验问题：

Sally wants her website to have a special layout on the first Tuesday of every month. She has the following controller and test code:

06000

What FIRST principle is not being followed?

1. Fast
2. Independent
3. Repeatable
4. Self-checking
5. Timely

我不知道哪个FIRST原则没有被遵守：

> Fast：代码似乎很快,因为它的测试没有什么复杂的.
>独立性：测试不依赖于其他测试.
>可重复：每次测试都会得到相同的结果. ‘special_index’如果是星期二,’index’如果不是星期二.
自检：测试可以自动检测是否通过.
>及时：代码和测试代码同时显示在这里.

因为测试代码是在控制器代码之后出现的,所以我选择了Timely的测验.但是我错了,回想起来,这不是一个好选择.我不知道在这里没有遵循哪个FIRST原则.
