Mockito方法存根中的對象參數

我試圖在Spring-Boot應用程序中對restController進行測試。Mockito方法存根中的對象參數

我想測試的方法是依賴於依賴於MongoRepository的服務的crud方法（插入）。

我已經做了如下，但我不明白爲什麼測試不工作，經過許多網絡研究。

@RunWith(SpringRunner.class) 
@WebMvcTest(value = ConfigTagController.class, secure = false) 
public class ConfigTagControllerTest { 

@Autowired 
MockMvc mvc; 

@MockBean 
ConfigTagService service; 


//dati mockati 
private ConfigTagEntity mockTag = new ConfigTagEntity("test",new ArrayList<>()); 
private ConfigTagEntity mockTag1 = new ConfigTagEntity("test1",new ArrayList<>()); 
private Collection<ConfigTagEntity> mockTagCollection = Arrays.asList(mockTag,mockTag1); 

//baseurl del controller 
private String baseUrl = "/v1/configtag"; 

@Test 
public void insertTest() throws Exception { 

    //Jackson library 
    ObjectMapper mapper = new ObjectMapper(); 

    //Object to JSON in String 
    String jsonInString = mapper.writeValueAsString(mockTag); 

    //stub del metodo 
    Mockito.when(service.insert(anyObject())).thenReturn(true); 

    MockHttpServletRequestBuilder request = MockMvcRequestBuilders.post(baseUrl); 
    request.param(jsonInString); 

    System.out.println(request); 


    this.mvc.perform(request) 
      .andExpect(status().isOk()) 
      .andExpect(content().contentTypeCompatibleWith(MediaType.APPLICATION_JSON)); 
}

當我嘗試運行測試，我得到這個錯誤

java.lang.IllegalArgumentException: 'values' must not be empty 

at org.springframework.util.Assert.notEmpty(Assert.java:228).......stacktrace

這是服務方法：

public boolean insert(ConfigTagEntity entity) { 
    if (configTagRepository.findByTagName(entity.getTagName()) == null) { 
     /* ... */ 
     return true; 
    } else { 
     return false; 
    } 
}

這是控制器方法

@Override 
@RequestMapping(value = "/configtag",method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE) 
public ResponseEntity<Void> insert(@RequestBody ConfigTagEntity entity) { 
    return checkCall(configTagService.insert(entity)); 
}

編輯堆棧跟蹤

凡'service'哪裏來的？你可以添加堆棧跟蹤？ –

是在測試課內，對不起，請繼續關注編輯 - >編輯完成 – Tommolo

我認爲stacktrace是需要找到您的問題。 –

你是通過你的JSON有效載荷的查詢參數。

所以不是

request.param(jsonInString);

你應該嘗試

request.content(jsonInString);

你也需要添加內容類型標題

request.contentType(MediaType.APPLICATION_JSON);

現在看到編輯後，我忘了把整個測試類 – Tommolo
