文件上传，如何进行单元测试吶？从网上找了半天没找到一个可行的方法， 经过我自己的琢磨，找到了一个方法。 现分享下， 欢迎留言评论。

我的Controller 是基于  HttpServletRequest request, HttpServletResponse response 作为方法的入参数; 大致如下 

 public ImportCampaignCustGroupResponse importCustGroup(

            HttpServletRequest request, HttpServletResponse response)

            throws Exception {

        return campaignCustGroupService.importExcelFile(request, response);

    }

单元测试代码如下 ; 注意必须在 创建MockMultipartHttpServletRequest 对象时，把WebApplicationContext 对象绑定到MockMultipartHttpServletRequest 实例上，否则在执行 

request.getServletContext() .getRealPath 这行代码时 会抛异常。

@RunWith(SpringRunner.class)

@SpringBootTest

@ComponentScan(basePackageClasses = MktCampaignCustGroupControllerTest.class)

@WebAppConfiguration

public class MktCampaignCustGroupControllerTest {

   @Autowired

    MktCampaignCustGroupController mktCampaignCustGroupController;

    @Autowired

    private WebApplicationContext wac;

 @Test

    public void testImportCustGroupTest() throws Exception {

       InputStream   inStream = MktCampaignCustGroupControllerTest.class.getResourceAsStream("index.txt");

    byte[] contentInvalid = new byte[inStream.available()];

    while(inStream.read(contentInvalid) != -1) {

    }

    MockMultipartHttpServletRequest request1 = new MockMultipartHttpServletRequest(this.wac.getServletContext());

    request1.setParameter("custGroupId", custGroupId);

    request1.setParameter("companyId", COMPANY.DM);

    request1.setMethod("POST");

    request1.setContentType("multipart/form-data");

    request1.addFile(new MockMultipartFile("custName", "\\index.txt", "text/plain", contentInvalid) );

    result = mktCampaignCustGroupController.importCustGroup(request1, response);

    Assert.assertNotNull(result);

    Assert.assertEquals(IResultCode.ILLEGAL_PARAMS, result.getResult().getResultCode()); 

    Assert.assertEquals("不支持导入非Excel文件", result.getResult().getResultMessage()); 

    System.out.println(result);

    }

}
