Spring mvc：使用MockMultipartFIle和其他表单数据对控制器进行单元测试

Question

我正在尝试对一个控制器进行单元测试，它接受一个＜code＞ArticleForm＜/code＞类型的请求对象，它包含一个＜code＞MultipartFile＜/code＞列表。

这是我正在尝试测试的控制器方法。

@RequestMapping(value = "/admin/save", method = RequestMethod.POST)
    public String save(@ModelAttribute @Valid ArticleForm articleForm,
                BindingResult result, RedirectAttributes redirectAttributes) {
  ....
 }

下面是Model属性对象ArticleForm

public class ArticleForm {
    private String id;

    @NotEmpty
    private String title;

    @NotEmpty
    private String description;

    private List<MultipartFile> images = Collections.emptyList();

  }

在我的单元测试中，我想提交3个＜code＞MockMulitpartFile＜/code＞对象以及＜code＞标题＜/code＞和＜code＞描述＜/code>

这是我尝试过的。填充标题和descriptionlist为空

@Test
public void adminController_saveArticleWithTitleAndDescription() throws Exception {

    final MockMultipartFile multipartFile1 = new MockMultipartFile("image1", "image1", "image/png", getResourceAsStream("/images/image1.png"));
    final MockMultipartFile multipartFile2 = new MockMultipartFile("image2", "image2", "image/png", getResourceAsStream("/images/image2.png"));
    final MockMultipartFile multipartFile3 = new MockMultipartFile("image3", "image3", "image/jpeg", getResourceAsStream("/images/image2.png"));

    mockMvc.perform(fileUpload("/admin/save")
            .file(multipartFile1)
            .file(multipartFile2)
            .file(multipartFile3)
            .contentType(MediaType.MULTIPART_FORM_DATA)
            .param("title", "Integration Testing")
            .param("description", "This is an integration test"))
            .andExpect(flash().attribute(FLASH_TYPE, is(FLASH_TYPE_SUCCESS)))
            .andExpect(flash().attribute(FLASH_MESSAGE, is(msgs.getMessage("controller.admin.save.success"))))
            .andExpect(status().isFound())
            .andExpect(view().name("redirect:/admin/add"));
}

如何将这3个＜code＞MockMultipartFile＜/code＞对象提交到＜code＞ArticleForm＜/code＞模型属性中的＜code＞图像＜/code>列表？

感谢您为解决此问题提供的帮助。

您的测试是正确的。使用“图像”作为文件名，如下所示。

final MockMultipartFile multipartFile1 = new MockMultipartFile("images", "image1", "image/png", getResourceAsStream("/images/image1.png"));
final MockMultipartFile multipartFile2 = new MockMultipartFile("images", "image2", "image/png", getResourceAsStream("/images/image2.png"));
final MockMultipartFile multipartFile3 = new MockMultipartFile("images", "image3", "image/jpeg", getResourceAsStream("/images/image2.png"));
