现在基本大公司都要求单元测试了，保证我们代码得质量，而我司更是要求覆盖率要达到60%以上，所以搞一下。

## 1.maven集成 ##

<dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-test</artifactId>
     	 <version>2.7.2</version>
     </dependency>
    
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>5.8.2</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.platform</groupId>
        <artifactId>junit-platform-runner</artifactId>
        <version>1.7.0</version>
        <scope>test</scope>
    </dependency>

## 2.maven单元测试覆盖率集成组件 ##

<build>
    <plugins>
    <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <version>2.22.2</version>
       <configuration>
           
           <skipTests>false</skipTests>
           <includes>
               <include>**/Test*.java</include>
               <include>**/*Test.java</include>
               <include>**/*Tests.java</include>
               <include>**/*TestCase.java</include>
               <include>**/*Spec.class</include>
           </includes>
       </configuration>
    </plugin>
     <plugin>
          <groupId>org.jacoco</groupId>
               <artifactId>jacoco-maven-plugin</artifactId>
               <version>0.8.7</version>
               <executions>
                   <execution>
                       <id>prepare-agent</id>
                       <goals>
                           <goal>prepare-agent</goal>
                       </goals>
                   </execution>
                   <execution>
                       <id>report</id>
                       <phase>test</phase>
                       <goals>
                           <goal>report</goal>
                       </goals>
                   </execution>
               </executions>
    </plugin> 
    
    </plugins>
    </build>

## 3.编写单元测试 ##

### **创建单测启动基类** ###

import org.springframework.boot.test.context.SpringBootTest;
    
    /**
     * @author cf
     * @date 2022/12/26下午 2:52
     */
    @SpringBootTest(classes = BasicPatternApplication.class)
    public class BaseTest {
        
    }

### resources里面得配置文件要迁移到test文件夹下，如下图： ###

### 编写单测类： ###

import com.qax.needle.framework.boot.model.PageResult;
    import org.junit.jupiter.api.Test;
    import org.junit.Assert;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mock.web.MockHttpServletResponse;
    
    /**
     * @author cf
     * @date 2022/12/26下午 2:51
     */
    public class AreasAccessInfoServiceImplTest extends BaseTest {
        
    
        @Autowired
        IAreasAccessInfoService iAreasAccessInfoService;
        private MockHttpServletResponse response;
    
        @Test
        public void page() {
        
            AreasAccessInfoPageReq areasAccessInfo = new AreasAccessInfoPageReq();
            Integer offset = 0;
            Integer limit = 10;
            areasAccessInfo.setCheckpointArea("110101");
            areasAccessInfo.setCheckpointName("检");
            areasAccessInfo.setLineType("1");
            areasAccessInfo.setCheckTimeEnd(1671465600000L);
            areasAccessInfo.setCheckTimeStart(1669824000000L);
            PageResult<AreasAccessInfoPageResp> page = iAreasAccessInfoService.page(areasAccessInfo, offset, limit);
            Assert.assertNotNull(page);
        }
    
        @Test
        public void statistics() {
        
            AreasAccessInfoPageReq areasAccessInfo = new AreasAccessInfoPageReq();
            areasAccessInfo.setCheckpointArea("110101");
            areasAccessInfo.setCheckpointName("");
            areasAccessInfo.setLineType("1");
            areasAccessInfo.setCheckTimeEnd(1671465600000L);
            areasAccessInfo.setCheckTimeStart(1669824000000L);
            AreasAccessInfoStatisticsResp statistics = iAreasAccessInfoService.statistics(areasAccessInfo);
            Assert.assertNotNull(statistics);
        }
    
        @Test
        public void export() {
        
            AreasAccessInfoPageReq areasAccessInfo = new AreasAccessInfoPageReq();
            areasAccessInfo.setCheckpointArea("110101");
            areasAccessInfo.setCheckpointName("检");
            areasAccessInfo.setLineType("1");
            areasAccessInfo.setCheckTimeEnd(1671465600000L);
            areasAccessInfo.setCheckTimeStart(1669824000000L);
            response = new MockHttpServletResponse();
            iAreasAccessInfoService.export(areasAccessInfo, response);
            Assert.assertNotNull("1");
        }
    }

## 4.执行单元测试覆盖率 ##

**这里有两个方法：  
1.使用maven自带得test，idea右侧maven模块执行项目下得test  
2.使用cmd命令，在你的项目pom文件所在目录 ，打开cmd，执行如下：**

mvn clean test org.jacoco:jacoco-maven-plugin:0.8.7:prepare-agent install -Dmaven.test.failure.ignore=true

**结果如下：打开site文件夹下得 index.html**

**出来了：**

## 5.有个坑 ##

**在编写单测得时候注意不要引入@Test得包为org.junit.Test，因为**

*  spring boot 2.2之前使用的是 Junit4
 *  spring boot 2.2之后使用的是 Junit5
