junit - 使用 PwerMock 模拟 ArrayList

Question

我正在尝试使用 Powermock 模拟数组列表，如下所示

MockDao 类

 PowerMockito.mockStatic(DailyReceiptsAndExceptionsDetailsDao.class);
    PowerMockito.mockStatic(UtilityFunctions.class);
    DailyReceiptsAndExceptionsExport dailyExceptionsExport = Mockito.mock(DailyReceiptsAndExceptionsExport.class);
    List<DailyReceiptsAndExceptionsDetailsGridDto> resultList = getDailyExceptions(inputDto);
    try{
        PowerMockito.whenNew(DailyReceiptsAndExceptionsExport.class).withArguments(Mockito.any(DailyReceiptsAndExceptionsDetailsInputDto.class)).thenReturn(dailyExceptionsExport);
        Mockito.when(DailyReceiptsAndExceptionsDetailsDao.getDailyReceiptsAndExceptions(Mockito.any(DailyReceiptsAndExceptionsDetailsInputDto.class))).thenReturn(resultList);
        Mockito.when(UtilityFunctions.processReportSchedule(scheduleId, jobId,dailyExceptionsExport,(List<DailyReceiptsAndExceptionResultDTO>)Mockito.any(), null, null)).thenReturn(true);
}catch(Exception e){
    }

我需要为以下类(class)编写测试。

    public static Response getOutboundAvgCubeAndWeightUtilization(
        @QueryParam("dc") String dc,
        @QueryParam("asn") String asn,
        @QueryParam("sortBy") String sort,
        @QueryParam("isExport") boolean isExport,
        @QueryParam("fileType") String fileType,
        @QueryParam("scheduleId") BigDecimal scheduleId,
        @QueryParam("jobId") BigDecimal jobId)  {

    ResponseDTO responseDto = new ResponseDTO();

    DailyReceiptsAndExceptionsDetailsInputDto inputDto = new DailyReceiptsAndExceptionsDetailsInputDto ();
    inputDto.setAsn(asn);
    inputDto.setDc(dc);
    inputDto.setSortBy(sort);
    inputDto.setFileType(fileType);
    inputDto.setExport(isExport);
    String filePath = "";
    try {
        DailyReceiptsAndExceptionResultDTO resultDto = DailyReceiptsAndExceptionsDetailsBusinessManager.getInstance().manageDailyReceiptsAndExceptionsDetails(inputDto);
        List<DailyReceiptsAndExceptionResultDTO> resultsList = new ArrayList<DailyReceiptsAndExceptionResultDTO>();
        resultsList.add(resultDto);
        if(scheduleId != null) {
            boolean responseStatus = UtilityFunctions.processReportSchedule(scheduleId, jobId, new DailyReceiptsAndExceptionsExport(inputDto), resultsList, null,null);

            responseDto.setResult(Boolean.toString(responseStatus));

            return CommonUtil.convertResponseToJson(responseDto);
        } 
   }

我的测试类如下。

   @Test
public void testGetOutboundAvgCubeAndWeightUtilization_4()
    throws Exception {
    String dc = "5854";
    String asn = "*";
    String sort = "SKU";
    boolean isExport = false;
    String fileType = "";
    BigDecimal scheduleId = new BigDecimal(100);
    BigDecimal jobId = new BigDecimal(100);
    DailyReceiptsAndExceptionsDetailsInputDto inputDto = new DailyReceiptsAndExceptionsDetailsInputDto ();
    inputDto.setAsn(asn);
    inputDto.setDc(dc);
    inputDto.setSortBy(sort);
    inputDto.setFileType(fileType);
    inputDto.setExport(isExport);
    DailyReceiptsAndExceptionsDetailsMockDAO.mockgetDailyExceptions(inputDto, scheduleId, jobId);
    Response result = DailyReceiptsAndExceptionsDetailsService.getOutboundAvgCubeAndWeightUtilization(dc, asn, sort, isExport, fileType, scheduleId, jobId);
    String output = result.getEntity().toString();      
    assertEquals(true,output.contains("\"result\": \"true\""));
}

当我运行测试用例时，它抛出错误，因为我认为列表的模拟不正确。

任何人都可以告诉如何运行这个测试场景....

Answer 1

你的模拟看起来没问题。

JUnit 未通过测试，因为该行

assertEquals(true,output.contains("\"result\": \"true\""));

失败:这意味着您的字符串 output不包含文本 "result": "true"

也许您找出问题所在的一种方法是打印 assertEquals() 之前的输出值。调用或使用调试器来查看输出的值是什么。

作为旁注，assertEquals(true, <condition>)非常冗长，你可以使用assertTrue(<condition>)相反。
