集成测试用例和文件上传

Question

我写了一些与使用spring上传文件相关的代码,它运行正常,现在我正在为此编写集成测试用例但我面临一些问题我的控制器方法,

@RequestMapping(value = "/{attributeName}/upload", method = RequestMethod.POST)
@ResponseBody
public Result uploadCompany(HttpServletRequest request,
        @RequestParam MultipartFile file, @PathVariable String attributeName,
        @RequestParam long dateKey)
        throws IOException, PromotionException {
    some code
}

测试用例

@Test
public void shouldReturnTrueStatusWhenUploadCompany() throws Exception {
    MockMultipartFile file = new MockMultipartFile("company_upload", "company_upload.csv",
            MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));
    mockMvc.perform(
            MockMvcRequestBuilders.fileUpload(
                    PROMOTION + StringUtils.replace(ATTRIBUTE_NAME, "{attributeName}", "COMPANY") + "/upload")
                    .file(file).param("dateKey", "852017")  .contentType(MediaType.MULTIPART_FORM_DATA)
                    .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk());

}

但我得到了

2017-05-09 13:42:42,506 ERROR [Test worker] INTERNAL_SERVER_ERROR: 
org.springframework.web.bind.MissingServletRequestParameterException: Required MultipartFile parameter 'file' is not present

我哪里错了？

Answer 1

改变你的路线

 MockMultipartFile file = new MockMultipartFile("company_upload", "company_upload.csv",
                    MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));  

至

 MockMultipartFile file = new MockMultipartFile("file", "company_upload.csv",
                    MediaType.MULTIPART_FORM_DATA_VALUE, EMPLOYEE_NUMBER_FILE_CONTENT.getBytes(UTF_8));

或者将控制器方法声明更改为类似的内容

 public Result uploadCompany(HttpServletRequest request,
                @RequestParam(value = "company_upload") MultipartFile file, @PathVariable String attributeName,
                @RequestParam long dateKey)
