如何在Java中返回Mockito 2.2中的Object？在我的情况下，返回的对象是NULL

Question

我试图返回响应对象，让程序使用响应对象的一些属性。 我正在使用MockitoJUnitRunner.class并模拟了notificationService类。

我将对象作为空对象。我需要它作为我返回的具有属性的对象。

    Request request = new Request();
    Element element = new Element("element");
    element.addContent(new Element("solnbr").setText("AWARD"));
    request.setData(element);

    SystemAccountResponse systemAccountResponse = new SystemAccountResponse();
    MultiValueMap<String, String> searchParams = new LinkedMultiValueMap<>();
    searchParams.add("solNumber","AWARD");
    OpportunityRESTResponse response = new OpportunityRESTResponse();
    Embedded embedded = new Embedded();
    List<Opportunity> opportunityList = new ArrayList<>();
    Opportunity opportunity = new Opportunity();
    opportunity.setId("1");
    opportunityList.add(0, opportunity);
    embedded.setOpportunity(opportunityList);
    response.setEmbedded(embedded);

    Page page = new Page();
    page.setTotalElements(10);
    response.setPage(page);
    when(opportunityRestService.getNoticeList(searchParams, systemAccountResponse)).thenReturn(response);

    notificationService.getNoticeListResponse(request);
