我正在使用
Spring MVC编写休息服务.这是课程的大纲：
@Controller
public class MyController{
@RequestMapping(..)
public void myMethod(...) throws NotAuthorizedException{...}
@ExceptionHandler(NotAuthorizedException.class)
@ResponseStatus(value=HttpStatus.UNAUTHORIZED,reason="blah")
public void handler(...){...}
}
我写了我的单元测试使用设计发布了here.测试基本如下：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(....)
public class mytest{
MockHttpServletRequest requestMock;
MockHttpServletResponse responseMock;
AnnotationMethodHandlerAdapter handlerAdapter;
@Before
public void setUp() {
requestMock = new MockHttpServletRequest();
requestMock.setContentType(MediaType.APPLICATION_JSON_VALUE);
requestMock.addHeader(HttpHeaders.ACCEPT,MediaType.APPLICATION_JSON_VALUE);
responseMock = new MockHttpServletResponse();
handlerAdapter = new AnnotationMethodHandlerAdapter();
}
@Test
public void testExceptionHandler(){
// setup ....
handlerAdapter.handle(...);
// verify
// I would like to do the following
assertThat(responseMock.getStatus(),is(HttpStatus.UNAUTHORIZED.value()));
}
}
但是,对handle的调用是抛出NotAuthorizedException.我已经读过这个设计是为了能够单元测试该方法抛出适当的异常,但是我想编写一个自动测试,该框架正确地处理这个异常,并且被测试类正确地实现了处理程序.有没有办法做到这一点？
请注意,我无法访问我可以发布的地方的实际代码.
此外,我对Spring 3.0.5或3.1.2有限(不幸的是).
解决方法
考虑使用Spring 3.2及其
mvc-test-framework
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("file:src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml")
public class WebMvcTest {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void getFoo() throws Exception {
this.mockMvc.perform(
get("/testx")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
)
.andExpect(status().isUnauthorized());
}
}
控制器代码
@Controller
public class MyController {
public class MyException extends RuntimeException {
};
@RequestMapping("/testx")
public void myMethod() {
throw new MyException();
}
@ExceptionHandler(MyException.class)
@ResponseStatus(value = HttpStatus.UNAUTHORIZED,reason = "blah")
public void handler() {
System.out.println("handler processed");
}
}
这个“测试”很顺利.
免责声明：目前我是Spring MVC测试中的noob,实际上是我的第一个测试.
upd：感谢Drake for the correction.
