java - for循环内if条件的Junit测试用例

问题描述

我的测试用例由于NullPointerException. 另外，我不确定如何在junit中处理或调试这个空错误。

以下是测试用例代码：

List<String> groupName = new ArrayList<String>();
when(claimGroupingHistoryRepository.getGroupingKeyName(1l)).thenReturn(groupName);
service.updateClaimGroupingKeyForDealer(dealer.getDealerId(), groupingKeyResource, userId);

由于以下代码null pointer，我的测试用例中出现了错误。如果评论if block 里面for-loop没有得到错误。不知道如何在这里测试 if 条件。

for(GroupingKeys groupingKey : groupingKeyResource.getGroupingKeys()){          
          if(groupingKey.getValue() != 0) {  // no sure how to check this condition using junit
              List<String> name = claimGroupingHistoryRepository.getGroupingKeyName(groupingKey.getId());
              for(String nameList:name) {
                  if(!groupingName.equalsIgnoreCase("")) {
                      groupingName = groupingName.concat(", ").concat(nameList);
                  } else {
                      groupingName = nameList;
                  }

              }
          } 
      }

以下是得到的测试用例错误：

ClaimServiceImplTest.shouldUpdateClaimGroupingKeyForDealerUpdate:6057 » NullPointer

请找到我的完整测试文件

更新：1*

public void shouldUpdateClaimGroupingKeyForDealerUpdate() throws Exception {    
         Dealer dealer = make(a(DealerMaker.Dealer));
         ClaimGroupingHistory claimGroupingHistory = make(a(ClaimGroupingHistoryMaker.ClaimGroupingHistory));

         String userId = "/user/0001";
         Status draft = make(a(Draft));
         User user = make(a(UserMaker.User, with(UserMaker.id, userId),with(UserMaker.email, "user@example.com"))).toUser();
            ArrayList<ClaimGroupingKeyMapping> mapping = new ArrayList<ClaimGroupingKeyMapping>();
            ClaimGroupingKeyMapping e = new ClaimGroupingKeyMapping();
            GroupingKeys groupingKeys= new GroupingKeys();
            groupingKeys.setValue(1l);
            groupingKeys.setCode("code");
            e.setValue(1l);
            e.setGroupingKeys(groupingKeys);
            mapping.add(e); 
        ArrayList<GroupingKeys> grpKey = new ArrayList<GroupingKeys>();
        grpKey.add(new GroupingKeys());
        GroupingKeyResource groupingKeyResource = new GroupingKeyResource();
        groupingKeyResource.setGroupingKeys(grpKey);

        ArrayList<ClaimGroupingHistory> historyLog=new ArrayList<ClaimGroupingHistory>();
        List<String> groupName=new ArrayList<String>();

        when(claimGroupingHistoryRepository.getClaimGroupingHistory(dealer.getDealerId())).thenReturn(historyLog);
        when(claimGroupingHistoryRepository.getGroupingKeyName(groupingKeys.getId())).thenReturn(groupName);

        service.updateClaimGroupingKeyForDealer(dealer.getDealerId(), groupingKeyResource, userId);

    }
