unit test HttpSessionRequiredException：预期的会话属性

Question

这是控制器：

@Controller("person")
@SessionAttributes("name")
public class SomeController {
    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public String save(@Valid Person person, Model model, @ModelAttribute("name") String name, BindingResult result) {}
}

这是测试：

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class PersonTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    @WithMockUser(username = "ram", authorities={"TEACHER"})
    public void checkPersonInfoWhenNameMissingNameThenFailure() throws Exception {
        MockHttpServletRequestBuilder createPerson = post("/person/add")
                .param("aa", "bb");

        mockMvc.perform(createPerson)
                .andExpect(model().hasErrors());
    }
}

因为控制器需要会话属性＆＃34; name＆＃34;，所以上面的测试抛出：

org.springframework.web.HttpSessionRequiredException: Expected session attribute 'name'

如何测试需要会话属性的控制器方法？ 感谢。

Answer 1

MockMvc有一种设置会话属性的方法。

Session attributes
