Jacoco收集单元测试、集成测试和系统功能测试覆盖率
2020-02-27
安装版本
2 被测系统代码示例
3 收集单元测试覆盖率
4 收集集成和功能测试覆盖率
代码覆盖率可在单元测试、系统测试和系统功能测试中使用
- 单元测试：测试左移，在代码提交前，可制定覆盖率要求，若不满足，不能提交
- 集成测试：接口测试
- 系统功能测试：通过用户界面操作
返回
- jacoco-0.8.2.zip 解压到：D:\software\jacoco
- apache-ant-1.10.6-bin.zip 解压到：D:\software\ant
返回
源代码：jacocodemo.zip
该示例示基于springboot框架的后端系统，主要是两个数字的加减乘除，提供restful接口给外部调用

执行maven命令
mvn test
命令执行日志如下：

生成exec文件和report文件如下图2所示
图2 单元测试单面覆盖率文件
由于类MathService方法add被调用，jacoco收集到此信息，如下图3所示
图3 覆盖率详情
返回
1 把被测被测系统打包并改名成 jacocodemo.jar
mvn package
2 启动被测系统，并通过javaagentJavaAgent会监听服务器端设置的TCP port，然后把收集到的信息（jacoco.exec）写入TCP connection
java -javaagent:D:/software/jacoco/lib/jacocoagent.jar=includes=*,output=tcpserver,port=6300,address=10.8.116.81,append=true -jar D:/Code/jacocodemo/target/jacocodemo.jar
3 配置ant的build.xml文件，并把它放到被测系统代码根目录
build.xml
<?xml version="1.0" encoding="UTF-8"?> <project name="JacocoDmo" xmlns:jacoco="antlib:org.jacoco.ant" default="jacoco"> <property name="jacocoantPath" value="D:\software\jacoco\lib\jacocoant.jar"/> <property name="jacocoexecPath" value="D:\Code\jacocodemo\target\coverage\jacoco-integation.exec"/> <property name="reportfolderPath" value="D:\Code\jacocodemo\target\coverage\jacoco-report"/> <property name="server_ip" value="10.8.116.81"/> <property name="server_port" value="6300"/> <property name="checkOrderSrcPath" value="D:\Code\jacocodemo\src\main\java" /> <property name="checkOrderClasspath" value="D:\Code\jacocodemo\target\classes" /> <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml"> <classpath path="${jacocoantPath}" /> taskdef> <target name="dump"> <jacoco:dump address="${server_ip}" reset="false" destfile="${jacocoexecPath}" port="${server_port}" append="true"/> target> <target name="report"> <delete dir="${reportfolderPath}" /> <mkdir dir="${reportfolderPath}" /> <jacoco:report> <executiondata> <file file="${jacocoexecPath}" /> executiondata> <structure name="JaCoCo Report"> <group name="Check Order related"> <classfiles> <fileset dir="${checkOrderClasspath}"> <exclude name="**/R.class"/> <exclude name="**/R$*.class"/> <exclude name="**/*$ViewInjector*.*"/> <exclude name="**/BuildConfig.*"/> <exclude name="**/Manifest*.*"/> fileset> classfiles> <sourcefiles encoding="UTF-8"> <fileset dir="${checkOrderSrcPath}" /> sourcefiles> group> structure> <html destdir="${reportfolderPath}" encoding="UTF-8" /> <csv destfile="${reportfolderPath}/coverage-report.csv" encoding="UTF-8"/> <xml destfile="${reportfolderPath}/coverage-report.xml" encoding="UTF-8"/> jacoco:report> target> project>
4 用postman调用被测系统接口，如下图4所示
图4 postman调用被测系统接口
5 执行ant dump拉取jacoco.exec覆盖率信息，执行ant report生成覆盖率报告
D:\Code\jacocodemo>ant dump Buildfile: D:\Code\jacocodemo\build.xml dump: [jacoco:dump] Connecting to /10.8.116.81:6300 [jacoco:dump] Dumping execution data to D:\Code\jacocodemo\target\coverage\jacoco-integation.exec BUILD SUCCESSFUL Total time: 0 seconds D:\Code\jacocodemo>ant report Buildfile: D:\Code\jacocodemo\build.xml report: [mkdir] Created dir: D:\Code\jacocodemo\target\coverage\jacoco-report [jacoco:report] Loading execution data file D:\Code\jacocodemo\target\coverage\jacoco-integation.exec [jacoco:report] Writing bundle 'Check Order related' with 6 classes BUILD SUCCESSFUL Total time: 0 seconds
从覆盖率报告可以看到subtract方法被覆盖，如图5所示
