我有一个方法方法位于标记为@Controller 的类中

@RequestMapping(value = "/addEvent", method = RequestMethod.POST)
    public String addEvent(Model model,
            @Valid @ModelAttribute("myEvent") Event event,
            BindingResult result, RedirectAttributes redirectAttributes,
            @RequestParam(required = true) Integer selectedEventTypeId,
            @RequestParam(required = true) Integer selectedEventStatusId) {

        if (result.getErrorCount() > 1 ){
            return "eventDetailsAdd";
        }
        eventService.addEvent(event, selectedEventTypeId, selectedEventStatusId);
        redirectAttributes.addAttribute("idEvent", event.getId());
        redirectAttributes.addAttribute("message", "added correctly at " + new Date() );
        return "redirect:eventDetails";
    }

使用 MockMvc 我可以检查什么？

更新

如果我编写以下代码： 

MockHttpServletRequestBuilder request = MockMvcRequestBuilders
                .get("/addEvent");
        ResultActions result = mockMvc.perform(request);

        result.andExpect(MockMvcResultMatchers.status().isOk());

我懂了：

java.lang.AssertionError: Status expected:<200> but was:<405>
    at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60)
    at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89)
    at org.springframework.test.web.servlet.result.StatusResultMatchers$5.match(StatusResultMatchers.java:549)
    ...

更新

我复制你的例子：

public class ModelAssertionTests {

        private MockMvc mockMvc;

        @Before
        public void setup() {

                SampleController controller = new SampleController("a string value", 3, new Person("a name"));

                this.mockMvc = standaloneSetup(controller)
                                .defaultRequest(get("/"))
                                .alwaysExpect(status().isOk())
                                .build();
        }


        @Test
        public void testHasErrors() throws Exception {
                mockMvc.perform(post("/persons")).andExpect(model().attributeHasErrors("person"));
        }




        @Controller
        private static class SampleController {

                private final Object[] values;

                public SampleController(Object... values) {
                        this.values = values;
                }

                @RequestMapping("/")
                public String handle(Model model) {
                        for (Object value : this.values) {
                                model.addAttribute(value);
                        }
                        return "view";
                }

                @RequestMapping(value="/persons", method=RequestMethod.POST)
                public String create(@Valid Person person, BindingResult result, Model model) {
                        return "view";
                }
        }

}
class Person{
    public Person(){}
    public Person(String name) {
        super();
        this.name = name;
    }

    String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

执行此代码后，我看到下一个跟踪：

我感到很困惑

MockMvc 将让您检查有关收到的响应的各种条件。您可以在http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/testing.html#spring-mvc-test-framework找到一些信息

特别是您可能对以下课程感兴趣： http: //docs.spring.io/spring/docs/3.2.x/javadoc-api/org/springframework/test/web/servlet/result/MockMvcResultMatchers.html

此类允许您访问其他结果匹配器，您可以使用这些结果匹配器来断言状态、内容、标题、模型、视图等的条件。

在您的情况下，您可以检查是否：

  • 状态为 200 OK 或者如果它是与重定向 url 一起进行的重定向
  • 已呈现正确的视图（如果错误计数高于 1）
  • 事件有错误
