我有A类,它依赖于B类.B类再次依赖C类.结构如下:

Class A(){
    @Autowired
    private B b;

    public void someMethod(){
        b.callAnotherMethodAndGetValue();
    }
}

Class B(){
    @Autowired
    private C c;

    public void callAnotherMethodAndGetValue(){
        c.callAnother();
    }
}

Class ATest(){
    @Spy
    private B b;

    public void someMethod(){
        // it goes into this method, and throws null pointer exception at
        // c.callAnother(); as c is null.
        b.callAnotherMethodAndGetValue();
    }
}

有什么方法可以让堆栈c.callAnother从Test Cases 流出来.没有做的时候b.callAnotherMethodAndGetValue();
