每个人都知道自动化测试是一件好事.

Everybody knows that automated testing is a good thing.

并不是每个人都确切地知道要测试什么.

Not everybody knows exacly what to test.

我的问题是是否应该在应用程序中测试诸如 validate_presence_of、validate_uniqueness_of 等原生验证.

My question is if native validations like validate_presence_of, validate_uniqueness_of and so on should be tested in the application.

在我的办公室里，我们三个人，一个认为应该进行测试，一个认为不应该进行测试，而我对此犹豫不决.

In my office we are three, one thinks it should be tested, one thinks it shouldn´t and I am up in the air.

推荐答案

是.

测试模型属性是否存在只是将 validates_presence_of 代码测试为实际测试的副产品，即 validates_presence_of 存在于您的模型中.

Testing that a model attribute is present or not is only testing the validates_presence_of code as a by-product of the real test which is that the validates_presence_of exists within your model.

如果有人注释掉一堆验证代码，然后忘记取消注释，那么这将不会被发现并可能导致各种问题.

If someone commented out a bunch of validation code and then forgot to uncomment it then this would go undetected and could cause all sorts of problems.

我测试它们，不是因为我认为它们不起作用，而是为了确保它们在需要时出现在我的模型中.

I test them, not because I think they don't work but to ensure that they are present in my model when required.
