@George Stocker“不幸的是，我们的代码库并不适合简单的测试。”每个人都同意单元测试有好处，但对于这个代码库来说，成本似乎很高。如果成本大于收益，那么他们为什么要对此充满热情呢?倾听你同事的意见;也许对他们来说，单元测试的痛苦比单元测试的价值更大。

具体地说，尽量尽快获得价值，而不是一些感觉良好的“xUnit是绿色的”价值，而是用户和维护者所重视的干净代码。也许您必须为一次迭代强制进行单元测试，然后讨论是否值得这样做。

Unit Testing is one of the most adopted methodologies for high quality code. Its contribution to a more stable, independent and documented code is well proven . Unit test code is considered and handled as an a integral part of your repository, and as such requires development and maintenance. However, developers often encounter a situation where the resources invested in unit tests where not as fruitful as one would expect. In an ideal world every method we code will have a series of tests covering it’s code and validating it’s correctness. However, usually due to time limitations we either skip some tests or write poor quality ones. In such reality, while keeping in mind the amount of resources invested in unit testing development and maintenance, one must ask himself, given the available time, which code deserve testing the most? And from the existing tests, which tests are actually worth keeping and maintaining? See here

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:)

你想说服谁?工程师还是经理?如果你试图说服你的工程师同事，我认为你最好的办法是迎合他们的愿望，让他们做出高质量的软件。有许多研究表明，它能发现漏洞，如果他们关心做好工作，这对他们来说就足够了。

如果您试图说服管理层，您将很可能不得不做一些成本/收益推理，说明未检测到的缺陷的成本大于编写测试的成本。一定要把不可转化的成本也包括在内，比如失去客户的信心等等。

根据我的经验，在复杂的软件环境中，单元测试和集成测试是“必须的”。

为了说服团队中的开发人员编写单元测试，您可能需要考虑在开发环境中集成单元测试回归分析(例如，在您的日常构建过程中)。

一旦开发人员知道如果单元测试失败，他们就不必花那么多时间调试它来发现问题，他们就会更有动力去编写这些测试。

这里有一个工具可以提供这样的功能:

作为一名物理专业的学生，我非常有动力去证明我的代码是可以正常工作的。您可以从逻辑上证明这一点，随着实现变得更加复杂，难度会急剧增加，或者您可以通过良好的测试对功能进行(尽可能接近的)经验证明。

如果不提供函数的逻辑证明，就必须进行测试。唯一的选择是说“我认为代码可以工作....”
