如何使用 jMockit 模拟标记为 final 并具有私有构造函数的类
我想使用 JMockit 编写一些基于状态的测试来模拟 CSVRecord.问题是 CSVRecord 是 final(这意味着我必须使用像 JMockit 这样的模拟框架)和 CSVRecord's构造函数具有包私有可见性.
I would like to write some state based tests using JMockit to mock up CSVRecord. The problem is that CSVRecord is final (which means I have to use a mocking framework like JMockit) and CSVRecord's constructor has package private visibility.
因为它是包私有的，所以我不能调用 new CSVRecord(arg, arg, ...)，这意味着我永远不能实例化我的模拟.它的父类 CSVParser 是唯一可以创建实例的类.
Since it is package private, I can't call new CSVRecord(arg, arg, ...), which means I can never I instantiate my mock.
Its parent, CSVParser, is the only class that can create an instance.
JMockit 有办法处理这种情况吗?
Does JMockit have a way to deal with this scenario?
注意:JMockit 或 Mockito 是我们在这个项目中使用的唯一框架.没有其他框架是可以接受的.我更喜欢使用 MockUp.
note: JMockit or Mockito are the only frameworks we use on this project. No other framework will be acceptable. My preference is to use a MockUp.
这听起来更像是 CSVRecord 不适合模拟.如果可能，最好针对另一个在内部使用它的公共类进行测试.
It sounds more like CSVRecord isn't a good candidate for mocking. If possible, tests targetting another public class which uses it internally would be preferable.
否则，JMockit 提供了一个带有 newInstance 方法的 Deencapsulation 类.
Otherwise, JMockit provides a Deencapsulation class with newInstance methods.
作为旁注，Mockito 仅支持基于行为的测试；JMockit 提供模型"(MockUp)，但这与编写纯基于状态的黑盒测试不同.
As a side note, Mockito only supports behavior-based tests; JMockit provides "mock-ups" (MockUp), but it's not the same as writing a pure state-based black box test.
