Spring Boot - MockMVC測試不起作用

Question

我有一個基本的SpringBoot應用程序。使用Spring初始化程序，嵌入式Tomcat，Thymeleaf模板引擎和包作爲可執行JAR文件。

我有這樣的控制器：

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

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

     return "tdk/deviceEvent/DeviceEventList"; 
    } 
} 

和這個其他測試類。使用Spring的MockMVC框架進行測試。該驅動在測試的MVC應用程序，就好像是在一個容器中運行，

@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)) // 
    } 

但我得到這個錯誤：

Answer 1

請嘗試這樣的：

@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)); 
    } 
}
