MockMvc测试发布请求
MockMvc测试发布请求
提问于 2017-05-28 10:14:46
我的REST控制器中有以下post路由：
@RequestMapping(value = "", method = RequestMethod.POST, produces =
"application/json")
public ResponseEntity saveMovie(@RequestBody Movie movie){
movieService.saveMovie(movie);
return new ResponseEntity<Movie>(movie, HttpStatus.OK);
}该路由使用一个服务将传入请求body的电影添加到数据存储中。服务方法的签名如下：
Movie saveMovie(Movie movie);我已经为它编写了以下测试和一个辅助方法：
@Test
public void saveMovie() throws Exception {
Movie movie1 = new Movie();
movie1.setImdbID("imdb1");
movie1.setTitle("Meter");
movie1.setYear("2015");
movie1.setPoster("meter.jpg");
when(movieService.saveMovie(movie1)).thenReturn(movie1);
mockMvc.perform(post("/v1/api/movie")
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(asJsonString(movie1))
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().contentType
(MediaType.APPLICATION_JSON_UTF8_VALUE));
verify(movieService, times(1)).saveMovie(movie1);
verifyNoMoreInteractions(movieService);
}
public static String asJsonString(final Object obj) {
try {
final ObjectMapper mapper = new ObjectMapper();
final String jsonContent = mapper.writeValueAsString(obj);
System.out.println(jsonContent);
return jsonContent;
} catch (Exception e) {
throw new RuntimeException(e);
}
}我得到以下错误：
Argument(s) are different! Wanted:
com.stackroute.ng2boot.service.MovieService#0 bean.saveMovie(
com.stackroute.ng2boot.domain.Movie@ae372b9
);
-> at
com.stackroute.ng2boot.controllers.MovieRestControllerTest.
saveMovie(MovieRestControllerTest.java:129)
Actual invocation has different arguments:
com.stackroute.ng2boot.service.MovieService#0 bean.saveMovie(
com.stackroute.ng2boot.domain.Movie@2098d37d
);
-> at
com.stackroute.ng2boot.controllers.MovieRestController.
saveMovie(MovieRestController.java:60)除了保存和更新之外，我需要传递一个Movie JSON作为请求主体，其他路由都通过了测试。请分享您的宝贵意见。
提前谢谢。

假设这是MovieService类：
@Component
public class MovieService {
private static List<Movie> movieList = new ArrayList<>();
static {
Movie m1 = new Movie("id1", "title1","2000", "poster1.jpg");
Movie m2 = new Movie("id2", "title2","2001", "poster2.jpg");
Movie m3 = new Movie("id3", "title3","2002", "poster3.jpg");
Movie m4 = new Movie("id4", "title4","2003", "poster4.jpg");
Movie m5 = new Movie("id5", "title5","2004", "poster5.jpg");
movieList.add(m1);
movieList.add(m2);
movieList.add(m3);
movieList.add(m4);
movieList.add(m5);
}
public Movie saveMovie(Movie movie){
movieList.add(movie);
return movie;
}
}假设这是MovieController类：
@RestController
public class MovieController {
private final MovieService movieService;
public MovieController(MovieService movieService) {
this.movieService = movieService;
}
@PostMapping(value = "", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity saveMovie(@RequestBody Movie movie){
movieService.saveMovie(movie);
return new ResponseEntity<>(movie, HttpStatus.OK);
}
}您可以使用MockMvc编写如下测试。该测试检查响应中的HttpStatus是否为预期的HttpStatus.OK，并检查saveMovie.saveMovie是否为movie6调用过一次。
@RunWith(SpringRunner.class)
@WebMvcTest(MovieController.class)
public class MovieControllerTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private MovieService movieService;
@Test
public void saveMovie() throws Exception {
Movie movie6 = new Movie("id6", "title6", "2006", "poster6.jpg");
String movie6AsJson = new ObjectMapper().writeValueAsString(movie6);
String url = "/";
when(movieService.saveMovie(any(Movie.class))).thenReturn(movie6);
RequestBuilder requestBuilder = MockMvcRequestBuilders.post(url)
.accept(MediaType.APPLICATION_JSON)
.contentType(MediaType.APPLICATION_JSON)
.content(movie6AsJson);
MvcResult mvcResult = mockMvc.perform(requestBuilder).andReturn();
int actualResult = mvcResult.getResponse().getStatus();
int expectedResult = HttpStatus.OK.value();
assertEquals("Result not as expected!",expectedResult,actualResult);
verify(movieService, times(1)).saveMovie(refEq(movie6));
}

你能不能试试：
import static org.mockito.Matchers.refEq;
----
verify(movieService, times(1)).saveMovie(refEq(movie1));Stack Overflow用户

您应该尝试使用：
verify(movieService).saveMovie(ArgumentMatchers.eq(movie1));确保在Movie类中实现了equals和hashCode方法也很好。
我注意到的另一件小事(然而，与您的问题无关)是您不需要同时使用times(1)和verifyNoMoreInteractions(movieService)。默认情况下，Mockito.verify应该被调用一次。看看它的源代码：
public static <T> T verify(T mock) {
return MOCKITO_CORE.verify(mock, times(1));
