springboot junit 测试controller 总结的相关知识点

测试所需的pom文件：

 自行查找

构建一个BaseTest类

类的的注解 

@RunWith(SpringJUnit4ClassRunner.class) 将SpringJUnit4ClassRunner.class 注入到本测试例中
@SpringBootTest(classes = {DlxRrsApplication.class, BaseTest.class}) 启动最基本的测试类

@AutoConfigureMockMvc 在springboot环境下，自动的将@springboot和@mockmvc创建mockmvc实例

 

在@Test之前 首选构建MockMvcBuilders工厂

测试controller 分为四步：构建请求对象，发送请求，获取服务器响应数据，判断执行结果

//构建对象

MockHttpServletRequestBuilder requestBuilder = null;
requestBuilder = MockMvcRequestBuilders.post(url);
requestBuilder.content(fileJsonStr);
requestBuilder.header("token", token);
requestBuilder.accept(MediaType.APPLICATION_JSON);
requestBuilder.contentType(MediaType.APPLICATION_JSON_UTF8);

//发送请求

ResultActions resultActions = mockMvc.perform(requestBuilder);
resultActions.andDo(MockMvcResultHandlers.print());
resultActions.andExpect(MockMvcResultMatchers.status().isOk());

//获取响应结果

MvcResult mvcResult = resultActions.andReturn();
MockHttpServletResponse mockHttpServletResponse = mvcResult.getResponse();
String contentAsString = mockHttpServletResponse.getContentAsString();

//执行判断结果

return JSONObject.parseObject(contentAsString, Jresult.class);

json文件解析为String对象
