我试图把一些单元/集成测试我的代码,测试休息控制器在春季启动使用独立MockMvc
我一个典型的REST应用建立与春天开机,我想测试AdminController save
方法:
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<Void> save(@RequestBody @Valid User user) {
user.setRole(Role.ROLE_ADMIN);
user.setPassword(passwordEncoder.encode(user.getPassword()));
return super.save(user);
}
的方法是直线前进,并通过数据库查询重复的,因为我使用户对象的属性username
独特:
@NotNull
@Column(updatable = false, unique = true)
private String username;
当我尝试两个用户节省使用相同的用户名,服务器拒绝与此out-of-the-box
JSON输出:(HTTP代码:500)
{
"timestamp": 1473942296273,
"status": 500,
"error": "Internal Server Error",
"exception": "org.springframework.dao.DataIntegrityViolationException",
"message": "could not execute statement; SQL [n/a]; constraint [uk_sb8bbouer5wak8vyiiy4pf2bx]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement",
"path": "/api/admins"
}
我确定这一点,因为它似乎春天开机默认行为是发送该处理异常错误/error
(由BasicErrorController
处理),并返回这个漂亮的JSON输出:
[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [uk_sb8bbouer5wak8vyiiy4pf2bx]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement] with root cause
DispatcherServlet : DispatcherServlet with name 'dispatcherServlet' processing POST request for [/error]
RequestMappingHandlerMapping : Looking up handler method for path /error
RequestMappingHandlerMapping : Returning handler method [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)]
DefaultListableBeanFactory : Returning cached instance of singleton bean 'basicErrorController'
OpenEntityManagerInViewInterceptor : Opening JPA EntityManager in OpenEntityManagerInViewInterceptor
HttpEntityMethodProcessor : Written [{timestamp=Thu Sep 15 16:09:07 AST 2016, status=500, error=Internal Server Error, exception=org.springframework.dao.DataIntegrityViolationException, message=could not execute statement; SQL [n/a]; constraint [uk_sb8bbouer5wak8vyiiy4pf2bx]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement, path=/api/admins}] as "application/json" using [org.springfr[email protected]1482cc8]
但是,当我试图测试这个使用的Mockito(see full test class):
@Transactional
@Test
public void testSaveDupValidUser() throws Exception {
User user = new User();
user.setUsername("admin");
this.mockMvc.perform(post("/api/admins")
.contentType(TestUtil.APPLICATION_JSON_UTF8)
.content(TestUtil.convertObjectToJsonBytes(user)))
.andDo(print())
.andExpect(status().isOk());
this.mockMvc.perform(post("/api/admins")
.contentType(TestUtil.APPLICATION_JSON_UTF8)
.content(TestUtil.convertObjectToJsonBytes(user)))
.andDo(print())
.andExpect(status().isInternalServerError());
}
而不是让500
内部服务器错误,我从JUnit的以下异常:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint ["UK_SB8BBOUER5WAK8VYIIY4PF2BX_INDEX_3 ON PUBLIC.""user""(USERNAME) VALUES ('admin', 1)"; SQL statement:
insert into "user" (id, created_by, created_date, modified_by, modified_date, enabled, password, role, username) values (null, ?, ?, ?, ?, ?, ?, ?, ?) [23505-192]]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:872)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:648)
所以,我的问题是:
如何启用使调度servlet来转发到/错误并返回相同的错误,如果应用程序正在运行(不在测试中)?
同时保持使用MockMvc standealone,而不用在其余方法中编写代码来处理异常并返回代码500
。
(我认为这可能是不可能的,所以我应该断言异常上,而不是或者我应该使用webAppContextSetup
什么是这里的最佳实践 - ???jHipster
例如使用独立MockMvc在所有的测试)

好的,你的观点是400不是500是100%正确,我同意你(谢谢)。但是让我困惑的是,在Spring的情况下,使用'@ Valid'注释来执行Bean验证,如果bean无效,则发送到'/ error',由'BasicErrorController'处理并导致'400'不仅在我使用Postman调用服务时,而且在我的集成测试中!请参阅https://github.com/MuhammadHewedy/match/blob/master/match-api/src/test/java/match/controllers/AdminControllerIntTest.java#L55,此测试用例尝试发送无效的用户对象,该对象由弹簧 –
我已经注意到,如果'@ Valid'弹簧在测试的情况下返回400个没有正文的错误请求。 –
@MuhammadHewedy:你有解决方案来获取测试例外吗? – gsmachado
