Spring mockMvc doesn't consider validation in my test

I am trying to set up an integration testing with mockMvc, and i have a problem with it. Indeed, spring doesn't integrate any validation annotation. For more precision, i put the code of the Controller class which could be tested : ``` @Controller public class UserRegisterController { private final Log log = LogFactory.getLog(UserRegisterController.class); private UserManager userManager; @Autowired public UserRegisterController(UserManager userManager){ this.userManager = userManager; } /** * Register a new user. * */ @RequestMapping(value = "/User/Register", method = RequestMethod.GET ) public @ResponseBody SimpleMessage submitForm( @Valid UserInfoNew userInfo, BindingResult result ){ if(log.isInfoEnabled()) log.info("Execute UserRegister action"); SimpleMessage message; try { if(result.hasErrors()){ if(log.isFatalEnabled()) log.fatal("Parameters sent by user for registering aren't conform. Errors are : " + result.getFieldErrors().toString()); throw new Exception(result.getFieldErrors().toString()); } User user = new User(); user.setLogin(userInfo.getLogin()); user.setFamilyName(userInfo.getFamilyName()); user.setFirstName(userInfo.getFirstName()); user.setPassword(userInfo.getPassword()); user.setDateBirthday(userInfo.getDateBirthday()); user.setEmail(userInfo.getEmail()); user.setMobile(userInfo.getMobile()); user.setAddress(userInfo.getAddress()); userManager.createUser(user); User newUser = userManager.findLastUserCreated(); //Change to null some sensitive or useless return parameters newUser.setPassword(null); // message = new SimpleMessage(null, newUser); } catch (Exception e) { if(log.isErrorEnabled()) log.error("A problem of type : " + e.getClass() + " has occured, with message : " + e.getMessage()); message = new SimpleMessage( new SimpleException(e.getClass(), e.getMessage()), null); } return message; } } ``` Then, the object with contain both hibernate and javax annotation for validation : ``` public abstract class UserParameters { @Min(1) protected Long id; @Length(min=4, max=20) protected String login; @Length(min=4, max=20) protected String familyName; @Length(min=4, max=20) protected String firstName; @Pattern(regexp="^.*(?=.{8,20})(?=.*[a-z]+)(?=.*[a-z]+)(?=.*[A-Z]+)(?=.*[A-Z]+)" + "(?=.*[0-9]+)(?=.*[0-9]+)(?=.*[@$%*#]+).*$") protected String password; @Past protected Calendar dateBirthday; @Email @Length(max=255) protected String email; @Pattern(regexp="^[0]{1}[67]{1}[ .-]{1}[0-9]{2}[ .-]{1}" + "[0-9]{2}[ .-]{1}[0-9]{2}[ .-]{1}[0-9]{2}$") protected String mobile; @Length(max=255) protected String address; protected Calendar dateCreation; protected Calendar dateLastAccess; } public class UserInfoNew extends UserParameters implements Serializable{ private static final long serialVersionUID = 4427131414801253777L; @NotBlank public String getLogin() { return login; } public void setLogin(String Login) { this.login = Login; } public String getFamilyName() { return familyName; } public void setFamilyName(String Name) { this.familyName = Name; } public String getFirstName() { return firstName; } public void setFirstName(String FirstName) { this.firstName = FirstName; } @NotBlank public String getPassword() { return password; } public void setPassword(String Password){ this.password = Password; } public Calendar getDateBirthday() { return dateBirthday; } public void setDateBirthday(Calendar strBirthDay) { this.dateBirthday = strBirthDay; } public String getEmail() { return email; } public void setEmail(String Mail) { this.email = Mail; } @NotBlank public String getMobile() { return mobile; } public void setMobile(String Mobile) { this.mobile = Mobile; } public String getAddress() { return address; } public void setAddress(String Address) { this.address = Address; } } ``` and the class which realizes the test: ``` @RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @ContextConfiguration(classes = { WebInit_Test.class, AppConfig_Test.class, WebConfig_1.class, WebConfig_2.class, WebSocketConfig.class }) public class UserControllersTest { @Autowired private WebApplicationContext wac; private MockMvc mockMvc; @Before public void setUp() throws Exception { this.mockMvc = MockMvcBuilders.webAppContextSetup(wac) .alwaysExpect(status().isOk()) .alwaysExpect(content().contentType("application/json;charset=UTF-8")) .build(); } @Test public void userRegister() throws Exception { //doesn't consider @Valid during test mockMvc.perform(get("/User/Register?Login=A&Password=aaAA&Mobile=0134320285") .contentType(MediaType.ALL) ) .andExpect(jsonPath("error").exists()); } } ``` When i launch the test, the error item doesn't exist, whereas login, password and mobile can't be validate by javax and hibernate annotation. Moreover, when i try to send an URL to localhost, validation worked and new user is not saved in database. As you can see, i use a java code configuration for my web layer, i suppose the problem come from it. Moreover i download a project from the spring team in github (link : github.com/spring-projects/spring-mvc-showcase) which details all kind of test we can do with mockmvc. The validation one (in "org.springframework.samples.mvc.validation" package) doesn't work with my project configuration but very well with in it's original config. To finish, i send you all my configuration classes ``` @Configuration public class WebInit_Test extends AbstractAnnotationConfigDispatcherServletInitializer { @Override protected Class<?>[] getRootConfigClasses() { return new Class<?>[] { AppConfig_Test.class }; } @Override protected Class<?>[] getServletConfigClasses() { return new Class<?>[] { WebConfig_1.class, WebConfig_2.class, WebSocketConfig.class }; } @Override protected String[] getServletMappings() { return new String[] { "/" }; } @Override protected void customizeRegistration(Dynamic registration) { registration.setInitParameter("dispatchOptionsRequest", "true"); registration.setLoadOnStartup(1); } } @Configuration @ImportResource({ "classpath:/applicationContext-dao.xml", "classpath:/applicationContext-datasource-test.xml", "classpath:/applicationContext-service.xml" }) public class AppConfig_Test { } @Configuration @EnableWebMvc @ComponentScan( basePackages = "project.web", excludeFilters = @ComponentScan.Filter(type= FilterType.ANNOTATION, value = Configuration.class) ) public class WebConfig_1 extends WebMvcConfigurationSupport { @Autowired private FormattingConversionServiceFactoryBean conversionService; @Bean @Override public FormattingConversionService mvcConversionService() { FormattingConversionService conversionService = this.conversionService.getObject(); addFormatters(conversionService); return conversionService; } } @Configuration public class WebConfig_2 extends WebMvcConfigurerAdapter{ @Override public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { configurer.enable(); } /** * Configure output mapping, see * {@link http://stackoverflow.com/questions/4823358/spring-configure-responsebody-json-format} * for more information * * @param converters * a list of {@link HttpMessageConverter<?>} */ @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { final MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter(); final ObjectMapper objectMapper = new ObjectMapper(); objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL); converter.setObjectMapper(objectMapper); converters.add(converter); super.configureMessageConverters(converters); } } @Configuration //@EnableScheduling @ComponentScan( basePackages="project.web", excludeFilters = @ComponentScan.Filter(type= FilterType.ANNOTATION, value = Configuration.class) ) @EnableWebSocketMessageBroker public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @Override public void configureMessageBroker(MessageBrokerRegistry config) { config.enableSimpleBroker("/friendship", "/message", "/journey", "/information"); config.setApplicationDestinationPrefixes("/app"); } @Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry.addEndpoint("/client").withSockJS(); } } ``` Thanks for your help.
