Coverage_Using_Jacoco_CN.md

使用Auto-unit-test-case-generator生成测试用例后，可通过jacoco来采集覆盖率结果。目前Auto-unit-test-case-generator自动生成的测试用例仅支持通过jacoco离线模式统计覆盖率。

配置Jacoco为离线模式

在被测系统的主pom中引入jacoco的离线模式配置：

1）新增plugin

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.22.2</version>
      <configuration>
        <systemPropertyVariables>
          <jacoco-agent.destfile>${project.build.directory}/coverage-reports/jacoco-ut.exec</jacoco-agent.destfile>
        </systemPropertyVariables>
      </configuration>
    </plugin>
    <plugin>
      <groupId>org.jacoco</groupId>
      <artifactId>jacoco-maven-plugin</artifactId>
      <version>0.8.6</version>
      <configuration>
        <dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
        <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
        <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
      </configuration>
      <executions>
        <execution>
          <id>default-instrument</id>
          <goals>
            <goal>instrument</goal>
          </goals>
        </execution>
        <execution>
          <id>default-restore-instrumented-classes</id>
          <goals>
            <goal>restore-instrumented-classes</goal>
          </goals>
        </execution>
        <execution>
          <id>default-report</id>
          <goals>
            <goal>report</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

2. 修改dependencies

<dependency>
  <groupId>org.jacoco</groupId>
  <artifactId>org.jacoco.agent</artifactId>
  <classifier>runtime</classifier>
  <scope>test</scope>
  <version>0.8.6</version>
</dependency>
