java不能用mockito模拟私有方法

Question

我试图用power mockito模拟一个私有方法，读完这篇文章后，我有了一些想法，我遵循了相同的结构：

example

这是我的课：

public class test(){
  private long verifyMarketEligibilityAndGetOfferDeliveryCalendar(long id)
  {
    some lins of code for connectiong to db
  }
  public long createOffer(long id){

    return verifyMarketEligibilityAndGetOfferDeliveryCalendar(id);
  }

}

下面是我的模拟测试：

test classUnderTest = PowerMockito.spy(new test());
        PowerMockito.doReturn(10).when(classUnderTest,
                "verifyMarketEligibilityAndGetOfferDeliveryCalendar", 10l);
        classUnderTest.createOffer(10);

现在我希望在调用createoffer之后，VerifyMarketEligibility和GetOfferDeliveryCalendar不会调用，而是返回数字10，但出于某种原因，程序开始执行VerifyMarketEligibility和GetOfferDeliveryCalendar类，从而执行与db相关的代码

有人能帮忙吗

PowerMockito需要声明这些注释

@RunWith(PowerMockRunner.class)
@PrepareForTest(classUnderTest.class)
