使用JUnit 和Jacoco进行单元测试

1、接口层测试

package com.pld.order.controller;


import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.pld.common.enums.ResultCodeEnum;
import com.pld.common.util.MsgResult;
import com.pld.order.PldOrderApplication;
import com.pld.order.dto.ContractMessageDTO;
import com.pld.order.dto.UpdateSignRequestDTO;
import com.pld.order.service.LaonContractService;
import lombok.extern.slf4j.Slf4j;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
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.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
@Slf4j
@SpringBootTest(classes = PldOrderApplication.class)
//@Transactional(transactionManager = "transactionManager")
public class DataProcessingControllerTest {

    @Autowired
    private WebApplicationContext context;

    @Autowired
    private MockMvc mockMvc;


    @MockBean
    private LaonContractService laonContractService;


    @Before
    public void before() throws Exception {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build();   //构造MockMvc
    }
    @Test
    @PrepareForTest(DataProcessingController.class)
    public void updateSignContractYsContractMsg() throws Exception {

        ContractMessageDTO contractMessageDTO = new ContractMessageDTO();
        contractMessageDTO.setYszyxyContractNo("77777777");

        //当调用第三方服务时，模拟数据返回
        Mockito.when(laonContractService.getContractMessageByOrderId(Mockito.anyString())).thenReturn(contractMessageDTO);

        log.info("更新签约表中应收账款转让协议编号");
        //String requestJson = JSON.toJSONString("");
        String responseString = mockMvc.perform(MockMvcRequestBuilders.get(Routes.UPDATE_YSCONTRACT_NO_IN_SIGN_CONTRACT).contentType(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andReturn()
                .getResponse()
                .getContentAsString();
        log.info("更新签约表中应收账款转让协议编号 responseString ={}", responseString);

        JSONObject jsonObject = JSONObject.parseObject(responseString);
        String resultCode  = jsonObject.getString ("code");
        String resultMsg  = jsonObject.getString ("msg");
        Assert.assertTrue(resultCode.equals(ResultCodeEnum.SUCCESS.getCode()) == true);
        log.info("更新签约表中应收账款转让协议编号 resultCode ={}, resultMsg={}", resultCode, resultMsg);
    }
}

2、方法层测试

package com.pld.order.service.impl;

import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)

@Slf4j
@SpringBootTest(classes = PldOrderApplication.class)
@Transactional(transactionManager = "transactionManager")
public class IDataProcessingServiceImplTest {

    @Autowired
    private WebApplicationContext context;

    @Autowired
    private MockMvc mockMvc;


    @MockBean
    private LaonContractService laonContractService;

    @Autowired
    private IDataProcessingServiceImpl dataProcessingService;


    @Before
    public void before() throws Exception {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build();   //构造MockMvc
    }

    /**
     * 测试批量更改数据
     *
     * @throws Exception
     */
    @Test
    @PrepareForTest(DataProcessingController.class)
    public void updateSignContractYsContractMsgTest() throws Exception {
        ContractMessageDTO contractMessageDTO = new ContractMessageDTO();
        contractMessageDTO.setYszyxyContractNo("77777777");

        //当调用第三方服务时，模拟数据返回
        Mockito.when(laonContractService.getContractMessageByOrderId(Mockito.anyString())).thenReturn(contractMessageDTO);
        Boolean actionResult = dataProcessingService.updateSignContractYsContractMsg();
        log.info("updateSignContractYsContractMsgTest actionResult ={}", actionResult);
        Assert.assertTrue(actionResult);
    }

    /**
     * 测试更改单比签约单数据
     *
     * @throws Exception
     */
    @Test
    @PrepareForTest(DataProcessingController.class)
    public void updateSignContractYsContractMsgOnRecordTest01() throws Exception {
        ContractMessageDTO contractMessageDTO = new ContractMessageDTO();
        contractMessageDTO.setYszyxyContractNo("77777777");

        //当调用第三方服务时，模拟数据返回
        Mockito.when(laonContractService.getContractMessageByOrderId(Mockito.anyString())).thenReturn(contractMessageDTO);

        Boolean actionResult = dataProcessingService.updateSignContractYsContractMsgOnRecord("525003373410254848", "9999999");
        log.info("updateSignContractYsContractMsgOnRecordTest actionResult ={}", actionResult);
        Assert.assertTrue(actionResult);
    }

    /**

        Boolean actionResult = dataProcessingService.updateSignContractYsContractMsgOnRecord("666666", "9999999");
        log.info("updateSignContractYsContractMsgOnRecordTest actionResult ={}", actionResult);
        Assert.assertTrue(actionResult == false);
    }
}

3、Jacoco配置

3.1 pom文件中引入jacoco依赖

 
            org.jacoco
            jacoco-maven-plugin
            0.8.0

3.2 配置插件

 
        org.jacoco
        jacoco-maven-plugin
        0.7.8
　　　　
        
            
                prepare-agent
                 
                     prepare-agent
                 
            
　　　　　　　　
             
                 check
                  
                      check
                   
            
　　　　　　　　
            
                 report
                 prepare-package
                 
                     report

3.3 配置规则


        org.jacoco
        jacoco-maven-plugin
        0.7.8
　　　　
        
            
                prepare-agent
                 
                     prepare-agent
                 
            
　　　　　　　　
             
                 check
                  
                      check
                   
            
　　　　　　　　
            
                 report
                 prepare-package

                            prepare-agent
                        
                    
                    
                        check
                        
                            check
                        
                    
                    
                        report
                        prepare-package
                        
                            report
