public方法返回Java中的私有类实例？ [英] public method returns private class instance in Java?

问题描述

我有一个方法，返回一个私人类的实例，我需要访问其方法从不同的包进行单元测试。这些类存在于同一个文件中。
它就像这样：

I have a method that returns an instance of a private class and I need access to its methods from a different package for unit testing. These classes live in the same file. It goes like this:

file：A.java

public class A{
    B b;
    public B getB(){
        return b;
    }  
    public setB(B b){
        this->b = b;
   }
}

class B{
    C c;
    public C getC(){
        return c;
    }
    public setC(C c){
        this->c = c;
   }
}

class C{
    public int getInt(){
        return 1;
    }
}

所以...基本上问题是：的方法在B或C到达以某种方式？

So... Basically the question is: are any of the methods in B or C reachable somehow? Am I obligated to place B and C in different files and make them public to accomplish that?

推荐答案

你想使用Reflection来反映用单元测试测试私有方法。您可以在这里阅读更多内容（请参阅答案）：
