SpringBoot MockMvc的单元测试

对于类的测试，可以有很多的方式进行实现，比如可以使用PostMan，使用HttpClient请求等，这里主要讲的是MockMcv的测试

一：引入依赖

     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
      </dependency>

　　

二：Demo如下：

package cn.wangtao.controller;

import cn.wangtao.HTTPEntity.RequestEntity.TestRequest;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import java.util.HashMap;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = cn.wangtao.run.Application.class)//注意这里的类要引入的是Main入口类
public class TestControllerTest {
    @Autowired
    private WebApplicationContext context;
    private MockMvc mockMvc;
    private ObjectMapper objectMapper=new ObjectMapper();

    @Before
    public void setUp() {
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();  //构造MockMvc
    }

    @Test
    public void testModelParam() throws Exception {
        TestRequest request = new TestRequest();
        request.setAge(18);
        request.setName("桃子");
        request.setAddress("上海");
        request.setServerType("ctr1");
        Map<String, String> map = new HashMap<String, String>();
        map.put("request",objectMapper.writeValueAsString(request));
        modelParam("/test",objectMapper.writeValueAsString(request));
    }

    @Test
    public void testMoreParam() throws Exception {
        Map<String, String> map = new HashMap<String, String>();
        map.put("name","wangtao");
        map.put("age","18");
        map.put("address","上海");
        map.put("serverType","ctr2");
        moreParam("/test2",map);
    }

    public void modelParam(String requestPath, String param ) throws Exception {
        MockHttpServletRequestBuilder mockHttpServletRequestBuilder
                = MockMvcRequestBuilders.get(requestPath)//自己选择方式
                                        .content(param)
                                        .contentType(MediaType.APPLICATION_JSON_UTF8);
        MvcResult result=mockMvc.perform(mockHttpServletRequestBuilder)
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andReturn();

        System.out.println("statusCode: "+statusCode);
        System.out.println("返回结果 content: "+content);
        Assert.assertEquals(statusCode, 200);
    }

    public void moreParam(String requestPath, Map<String,String> map ) throws Exception {
        MockHttpServletRequestBuilder mockHttpServletRequestBuilder = MockMvcRequestBuilders.get(requestPath);//请求方式自己定
        //参数封装
        for (Map.Entry<String,String> entry:map.entrySet() ){
            mockHttpServletRequestBuilder.param(entry.getKey(),entry.getValue());
        }
        mockHttpServletRequestBuilder.contentType(MediaType.APPLICATION_JSON_UTF8);
        MvcResult result=mockMvc.perform(mockHttpServletRequestBuilder)

        System.out.println("返回结果 content: "+content);

    }
