Powermock构造函数mock对实例化的对象没有影响

Question

    Class  A{
    B objB = new B();
    objB.someBMethod();
    }
    Class B{
    public void someBMethof(){
    C objC = new C();
    }
    }
    class C{
    int a=1;
    public C(){}
    public C(int v){
    a=v;
    }
    }
@RunWith( PoswerMockRunner.class )
@PrepareForTest({ A.class, B.class, C.class})
Class TestApp{
    @Mock
    C mockC;
    PowerMockito.whenNew( C.class ).withNoArguments().thenReturn(mockC);
}

上面的代码捕获了我要做的事情。但是whenNew()似乎没有工作，当我尝试调试创建的C对象不是mock。不知道发生了什么。如果能给点指点，我将不胜感激。由于

您提供了一些代码，所以谢谢。但是下次，考虑发布一个sscce(正确的(可编译的)示例)。

我试过(并修复你的代码)，它工作。这是我对你的代码的版本:

public class A {
    public int someAMethod() {
        B objB = new B();
        return objB.someBMethod();
    }
}
public class B {
    public int someBMethod() {
        C objC = new C();
        return objC.getA();
    }
}
