这是非常以. net为中心的，但是有人尝试过Pex吗?

我非常怀疑，直到我尝试了——哇，多么精彩的表演。以前我想“我不会被这个概念说服，直到我明白它实际上对我有什么好处”。我只跑了一次就改变了主意，说:“我不在乎你怎么知道那里有致命异常的风险，但现在我知道我必须处理它”

也许这种行为唯一的缺点是它会标记所有事情，给你六个月的积压。但是，如果你有代码债，你总是有代码债，只是你不知道而已。告诉项目经理可能有20万个故障点，而你之前只知道有几十个，这是一个令人讨厌的前景，这意味着首先解释这个概念是至关重要的。

当涉及到重构或重写一段代码时，单元测试也特别有用。如果您有良好的单元测试覆盖率，您就可以满怀信心地进行重构。如果没有单元测试，通常很难确保您没有破坏任何东西。

当您手动测试软件时，通常会使用一小组测试/操作。最终，您将自动修改输入数据或操作，以便围绕已知问题进行导航。应该有单元测试来提醒您某些事情不能正常工作。

我建议在编写代码之前编写测试，添加新的测试/数据来改进主代码的功能!

多年来，我一直试图说服人们，他们需要为自己的代码编写单元测试。无论他们是先编写测试(如TDD)还是在编写功能之后，我总是试图向他们解释对代码进行单元测试的所有好处。几乎没有人反对我。你不能否认一些显而易见的事情，任何聪明的人都会看到单元测试和TDD的好处。

单元测试的问题在于它需要行为上的改变，而要改变人们的行为是非常困难的。用语言，你会让很多人同意你的观点，但你不会看到他们做事的方式有太多变化。

你必须通过行动来说服人们。你的个人成功会比你的争论吸引更多的人。如果他们看到你不只是在谈论单元测试或TDD，而是在做你鼓吹的事情，而且你是成功的，人们就会试图模仿你。

You should also take on a lead role because no one writes unit test right the first time, so you may need to coach them on how to do it, show them the way, and the tools available to them. Help them while they write their first tests, review the tests they write on their own, and show them the tricks, idioms and patterns you've learned through your own experiences. After a while, they will start seeing the benefits on their own, and they will change their behavior to incorporate unit tests or TDD into their toolbox.

改变不会在一夜之间发生，但只要有一点耐心，你就可能实现你的目标。

Yes - Unit Testing is definitely worth the effort but you should know it's not a silver bullet. Unit Testing is work and you will have to work to keep the test updated and relevant as code changes but the value offered is worth the effort you have to put in. The ability to refactor with impunity is a huge benefit as you can always validate functionality by running your tests after any change code. The trick is to not get too hung up on exactly the unit-of-work you're testing or how you are scaffolding test requirements and when a unit-test is really a functional test, etc. People will argue about this stuff for hours on end and the reality is that any testing you do as your write code is better than not doing it. The other axiom is about quality and not quantity - I have seen code-bases with 1000's of test that are essentially meaningless as the rest don't really test anything useful or anything domain specific like business rules, etc of the particular domain. I've also seen codebases with 30% code coverage but the tests were relevant, meaningful and really awesome as they tested the core functionality of the code it was written for and expressed how the code should be used.

在探索新的框架或代码库时，我最喜欢的一个技巧是为“它”编写单元测试，以发现事物是如何工作的。这是一个学习新事物的好方法，而不是阅读枯燥的文档:)
