        doReturn("Mocked response").when(myClassSpy, "myPrivateMethod", anyString());

        // 调用myPrivateMethod并验证结果
        String response = myClassSpy.getClass().getDeclaredMethod("myPrivateMethod", String.class).invoke(myClassSpy, "testInput");

        // 验证myPrivateMethod是否被调用
        verify(myClassSpy, times(1)).invoke("myPrivateMethod", anyString());
    }
