Powermock模拟构造函数有实例化对象没有任何影响(Powermock constructor

    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);

}

上面的代码捕获什么即时试图做的。但whenNew（）似乎并没有工作，当我尝试debuggin创建的C对象是不假。不知道发生了什么。一些指针将不胜感激。谢谢

你提供了一些代码，这样的感谢。但是接下来的时间，考虑到后期的SSCCE（正确（ 可编译 ）例子）。

我试图（和修复您的代码）和它的作品。这是我的版本的代码：

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();
    }
}

@PrepareForTest({ A.class, B.class, C.class })
public class TestApp {

    @Mock
    C mockC;

    @Test
    public void shoudlReturnTheCValue() throws Exception {
        when(mockC.getA()).thenReturn(666);
        PowerMockito.whenNew(C.class).withNoArguments().thenReturn(mockC);
        assertEquals(666, new A().someAMethod());
    }
}
