junit测试中的MockMVC - 检查List <Object>和Map <Enum,Object>的结果

Question

我有mockMVC的问题和用它编写的测试.我的测试失败了.我有两种测试方法:

@Test
public void getPersonsForApiConsumerTest() throws Exception {
    mockMvc.perform(get(getUri("/consumers/1/persons")))
            .andExpect(status().isOk())
            .andExpect(jsonPath("$", hasSize(2)))
            .andExpect(jsonPath("$[1].name", is("Ligza")))
            .andExpect(jsonPath("$[2].name", is("Vekrir")));

}

@Test
public void getPersonsForApiConsumerMapTest() throws Exception {
    mockMvc.perform(get(getUri("/consumers/1/persons/map")))
            .andExpect(status().isOk())
            .andExpect(jsonPath("$[1].name", is("Verkir")))
            .andExpect(jsonPath("$[2].name", is("Ligza")));
}

具有映射的Rest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);
    }

通过Postman我可以获得这样的数据:

列表:

[
    {
        "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"
    }
]

对于地图:

{
    "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": []
}

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,或者以它已经可以的方式轻松检查它？

Answer 1

该jsonPath助手是断言你的反应是从消费者的API的角度有效非常有用的; 这些消费者会收到JSON repsonse,因此在JSON上执行断言是有意义的.

以下断言将适用于来自的有效负载 /consumers/1/persons

.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,如果你真的想主张反对原来的类型(例如PersonDto),那么你可以阅读整个JSON字符串,并使用JSON映射器(如杰克逊或GSON)反序列化它放回原班表示.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
