junit测试中的MockMVC - 检查List <object>和Map <enum，object =“”>的结果

标签： java spring testing junit mockmvc

我遇到了用mockMVC和用它编写的测试的问题。我的测试失败了。 我有两种测试方法：

 @RequestMapping(value = "/{consumerId}/persons")
    public List<PersonDto> getPersonsForApiConsumer(@PathVariable("consumerId") Integer consumerId) throws IOException {
        return apiConsumerService.getPersonsListForApiConsumer(consumerId);
    }

    @RequestMapping(value = "/{consumerId}/persons/map")
    public Map<ApiConsumerPersonRole, List<Person>> getPersonsForApiConsumerMap(@PathVariable("consumerId") Integer consumerId) throws IOException {
        return apiConsumerService.getPersonsMapForApiConsumer(consumerId);
    }

使用映射的休息方法：

[
    {
        "id": 1,
        "firstName": "Ligza",
        "lastName": "Zetasor",
        "role": "REPRESENTATIVE",
        "phone": "123123123",
        "email": "ligza.zetasor@gmail.com"
    },
    {
        "id": 4,
        "firstName": "Vekrir",
        "lastName": "Omegaram",
        "role": "SECURITY_OFFICER",
        "phone": "354654545",
        "email": "vekrir.omegaram@gmail.com"
    }
]

通过Postman我可以获得这样的数据：

列表：

{
    "SECURITY_OFFICER": [
        {
            "id": 4,
            "firstName": "Vekrir",
            "lastName": "Omegaram",
            "telephone": "354654545",
            "email": "vekrir.omegaram@gmail.com"
        }
    ],
    "REPRESENTATIVE": [
        {
            "id": 1,
            "firstName": "Ligza",
            "lastName": "Zetasor",
            "telephone": "123123123",
            "email": "ligza.zetasor@gmail.com"
        }
    ],
    "COMPLAINT_OFFICER": [],
    "LOCAL_REPRESENTATIVE": []
}

for map：

我没有任何线索如何正确地写它。我想检查一下这个列表和地图中的数据。

是否可以将其流式传输到该集合中，或者以已经完成的方式轻松检查它？

答案 0 :(得分：9)

jsonPath帮助程序非常有用，可以从API用户的角度断言您的回复是否有效;这些消费者会收到JSON repsonse，因此在JSON上执行断言是有意义的。

以下断言适用于/consumers/1/persons

的有效负载 
.andExpect(jsonPath("$[0].firstName", is("Ligza")))
.andExpect(jsonPath("$[1].firstName", is("Vekrir")))

因此，该数组是基于0的，您可以通过（区分大小写）名称访问每个元素中的条目。

但是，如果你真的想要对原始类型（例如PersonDto）断言，那么你可以读取整个JSON字符串并使用JSON映射器（例如Jackson或Gson ）将其反序列化为其原始类表示。例如：

MvcResult result = mockMvc.perform(get(getUri("/consumers/1/persons")))
        .andExpect(status().isOk())
        .andReturn();

ObjectMapper mapper = new ObjectMapper();

// this uses a TypeReference to inform Jackson about the Lists's generic type
List<PersonDto> actual = mapper.readValue(result.getResponse().getContentAsString(), new TypeReference<List<PersonDto>>() {});

// now just assert equality (or whatever) against the actual PersonDto
