junit 测试中的 MockMVC - 检查 List<Object> 和 Map<Enum, Object> 的结果
MockMVC in junit tests - checking result for List<Object> and Map<Enum, Object>
我对 mockMVC 和用它编写的测试有问题。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")));
}
带映射的休息方法：
@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"
}
]
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": []
}
我不知道如何正确地写它。我想检查此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以已经编写的方式轻松检查它？

jsonPath 助手对于从 API 的消费者的角度断言您的响应是有效的非常有用；这些消费者收到 JSON 回复，因此对 JSON.
执行断言是有意义的
以下断言适用于来自 /consumers/1/persons
的有效载荷
.andExpect(jsonPath("$[0].firstName", is("Ligza")))
.andExpect(jsonPath("$[1].firstName", is("Vekrir")))
因此，该数组是从 0 开始的，您可以通过（区分大小写的）名称访问每个元素中的条目。
但是，如果您真的想针对原始类型进行断言（例如 PersonDto），那么您可以读取整个 JSON 字符串并使用 JSON 映射器（例如 Jackson or Gson) 将其反序列化回其原始 class 表示形式。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
我对 mockMVC 和用它编写的测试有问题。我的测试失败了。 我有两种测试方法：

.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")));
}
带映射的休息方法：
@RequestMapping(value = "/{consumerId}/persons")
public List<PersonDto> getPersonsForApiConsumer(@PathVariable("consumerId") Integer consumerId) throws IOException {

public Map<ApiConsumerPersonRole, List<Person>> getPersonsForApiConsumerMap(@PathVariable("consumerId") Integer consumerId) throws IOException {
