Powermock構造函數嘲笑對實例化對象沒有影響

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); 

} 

上面的代碼捕獲了即時消息試圖做的事情。但whenNew（）似乎沒有工作，當我嘗試調試創建的C對象不是模擬。不知道發生了什麼。一些指針將不勝感激。謝謝

你提供了一些代碼，謝謝。但下次考慮發佈sscce（正確（Compilable）示例）。

我試過（並修復你的代碼），它的工作原理。這是我的版本的代碼：

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(); 
    } 
}
