使用Spring MVC Test对多部分POST请求进行单元测试
使用Spring MVC Test对多部分POST请求进行单元测试
提问于 2014-02-16 00:58:59
我有以下保存汽车的请求处理程序。我已经验证了，当我使用cURL时，这是可行的。现在我想用Spring MVC Test对这个方法进行单元测试。我试过使用fileUploader，但我没办法让它工作。我也没有设法添加JSON部件。
如何使用Spring MVC Test对此方法进行单元测试？我找不到任何关于这方面的例子。
@RequestMapping(value = "autos", method = RequestMethod.POST)
public ResponseEntity saveAuto(
@RequestPart(value = "data") autoResource,
@RequestParam(value = "files[]", required = false) List<MultipartFile> files) {
// ...
}我想为我的auto +一个或多个文件上传一个JSON表示。
我会在正确答案的基础上加上100！

由于MockMvcRequestBuilders#fileUpload已被弃用，因此您需要使用返回MockMultipartHttpServletRequestBuilder的MockMvcRequestBuilders#multipart(String, Object...)。然后链接一堆file(MockMultipartFile)调用。
下面是一个有效的示例。给定一个@Controller
@Controller
public class NewController {
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
public String saveAuto(
@RequestPart(value = "json") JsonPojo pojo,
@RequestParam(value = "some-random") String random,
@RequestParam(value = "data", required = false) List<MultipartFile> files) {
System.out.println(random);
System.out.println(pojo.getJson());
for (MultipartFile file : files) {
System.out.println(file.getOriginalFilename());
}
return "success";
}
static class JsonPojo {
private String json;
public String getJson() {
return json;
}
public void setJson(String json) {
this.json = json;
}
}
}和单元测试
@WebAppConfiguration
@ContextConfiguration(classes = WebConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class Example {
@Autowired
private WebApplicationContext webApplicationContext;
@Test
public void test() throws Exception {
MockMultipartFile firstFile = new MockMultipartFile("data", "filename.txt", "text/plain", "some xml".getBytes());
MockMultipartFile secondFile = new MockMultipartFile("data", "other-file-name.data", "text/plain", "some other type".getBytes());
MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json", "{\"json\": \"someValue\"}".getBytes());
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
mockMvc.perform(MockMvcRequestBuilders.multipart("/upload")
.file(firstFile)
.file(secondFile)
.file(jsonFile)
.param("some-random", "4"))
.andExpect(status().is(200))
.andExpect(content().string("success"));
}
}和@Configuration类
@Configuration
@ComponentScan({ "test.controllers" })
@EnableWebMvc
public class WebConfig extends WebMvcConfigurationSupport {
@Bean
public MultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
return multipartResolver;
}
}测试应该会通过，并给出以下输出
4 // from param
someValue // from json file
filename.txt // from first file
other-file-name.data // from second file需要注意的是，除了使用不同的内容类型外，您发送的JSON与任何其他多部分文件一样。

方法MockMvcRequestBuilders.fileUpload已弃用，请改用MockMvcRequestBuilders.multipart。
这是一个示例：
import static org.hamcrest.CoreMatchers.containsString;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.mock.web.MockMultipartFile;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.multipart.MultipartFile;
/**
* Unit test New Controller.
*
*/
@RunWith(SpringRunner.class)
@WebMvcTest(NewController.class)
public class NewControllerTest {
private MockMvc mockMvc;
@Autowired
WebApplicationContext wContext;
@MockBean
private NewController newController;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(wContext)
.alwaysDo(MockMvcResultHandlers.print())
.build();
}
@Test
public void test() throws Exception {
// Mock Request
MockMultipartFile jsonFile = new MockMultipartFile("test.json", "", "application/json", "{\"key1\": \"value1\"}".getBytes());
// Mock Response
NewControllerResponseDto response = new NewControllerDto();
Mockito.when(newController.postV1(Mockito.any(Integer.class), Mockito.any(MultipartFile.class))).thenReturn(response);
mockMvc.perform(MockMvcRequestBuilders.multipart("/fileUpload")
.file("file", jsonFile.getBytes())
.characterEncoding("UTF-8"))
.andExpect(status().isOk());
}

看看这个取自spring MVC展示案例的例子，这是到source code的链接。
@RunWith(SpringJUnit4ClassRunner.class)
public class FileUploadControllerTests extends AbstractContextControllerTests {
@Test
public void readString() throws Exception {
MockMultipartFile file = new MockMultipartFile("file", "orig", null, "bar".getBytes());
webAppContextSetup(this.wac).build()
.perform(fileUpload("/fileupload").file(file))
.andExpect(model().attribute("message", "File 'orig' uploaded successfully"));
}
