Mockmvc,用于接受多部分文件的DELETE方法

我正在尝试为一个具有 删除

我知道我可以像这样做一个简单的删除:

    MvcResult result = mockMvc.perform(MockMvcRequestBuilders.delete(
            "/deletecat/catname/Oscar"))
            .andExpect(status().isOK)
            .andReturn();

我可以这样对一个多部分文件进行POST:

MockMultipartFile multipartFile = new MockMultipartFile("file", new FileInputStream(TEST_RESOURCES_FOLDER + "Cats.csv"));
MvcResult result = mockMvc.perform(MockMvcRequestBuilders.multipart("/uploadcats")
   .file(multipartFile)
   .param("ownerName", "Austin Powers"))
   .andExpect(status().isOk())
   .andReturn();

但当我试图把它们结合在一起写下:

 MvcResult result = mockMvc.perform(
            MockMvcRequestBuilders.delete(
                    "/deletecats", 
                    multipartFile, "Austin Powers"))
            .andExpect(status().isOk())
            .andReturn();

“当前请求不是多部分请求” :

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Current request is not a multipart request

HTTP协议是否可能不支持使用多部分文件进行删除?
