Question

我有一个基本的SpringBoot应用程序。使用Spring Initializer，嵌入式Tomcat，Thymeleaf模板引擎和包作为可执行的JAR文件。

我有这个控制器：

@Controller
@RequestMapping("/deviceevent")
public class DeviceEventController {

    @RequestMapping(value={ "/list"}, method = { RequestMethod.GET})
    public String deviceeventList()  {

        return "tdk/deviceEvent/DeviceEventList";
    }
}

和另一个测试类。使用Spring的MockMVC框架进行测试。这会在测试中驱动MVC应用程序，就像它在容器中运行一样，

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class MockMvcTests {

    // Pull in the application context created by @ContextConfiguration
    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        // Setup MockMVC to use our Spring Configuration
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }


    @Test
    public void getDeviceEventsTest() throws Exception {
        this.mockMvc
                .perform(get("/deviceevent/list") //
                        .accept(MediaType.parseMediaType("text/html;charset=UTF-8")))
                .andExpect(status().isOk()) //
                .andExpect(model().size(1)) //
    }

但我收到了这个错误：

请尝试这样：

@RunWith(SpringRunner.class)
@WebMvcTest(WarehouseController.class)
public class WarehosueControllerTest {

    @Autowired
    private MockMvc mvc;


    @MockBean
    WarehouseService warehouseService;//the business service



    @Test
    public void testGetWarehouses() throws Exception{
        List<Long> list = new ArrayList<>();
        list.add(1L);

        WarehouseDTO warehouseDTO = new WarehouseDTO();
        List<WarehouseDTO> warehouseDTOs = new ArrayList<>();
        warehouseDTO.setId(1L);
        warehouseDTO.setCode("test_code");
        warehouseDTO.setName("test_name");
        warehouseDTO.setAddress("adress value");
        warehouseDTOs.add(warehouseDTO);
        given(this.warehouseService.getWarehouses(0, list))
                .willReturn(warehouseDTOs);

        this.mvc.perform(get("/api/warehouses?filterType=0&ids=1")
                .header("Accept-Language", "en-US,en;q=0.8,zh-CN;q=0.6,zh;q=0.4")
                .accept(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk())
                .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8))

                //check if the jason node exsits
                .andExpect(jsonPath("$.errorCode").exists())
                .andExpect(jsonPath("$.payload[0].name").exists())
                .andExpect(jsonPath("$.payload[0].code").exists())
                .andExpect(jsonPath("$.payload[0].id").exists())

                //check the type of json node
                .andExpect(jsonPath("$.errorCode").isString())
                .andExpect(jsonPath("$.payload[0].name").isString())
                .andExpect(jsonPath("$.payload[0].code").isString())
                .andExpect(jsonPath("$.payload[0].id").isNumber())

                //check the return value
                .andExpect(jsonPath("$.errorCode").value(""))
                .andExpect(jsonPath("$.payload[0].name").value("test_name"))
                .andExpect(jsonPath("$.payload[0].code").value("test_code"))
                .andExpect(jsonPath("$.payload[0].address").value("adress value"))
                .andExpect(jsonPath("$.payload[0].id").value(1));
    }
}

Spring Boot - MockMVC测试不起作用
