JaCoCo

一般我們會寫測試程式，但是測一個Function是測試，測試十個Function也是測試，所以我們需要一個方式來評斷測試的涵蓋率。 一般的設定如下:

<build>
  <plugins>
    <plugin>
      <groupId>za.co.absa.jacoco</groupId>
      <artifactId>jacoco-maven-plugin</artifactId>
      <version>0.8.11</version>
      <executions>
        <execution>
          <id>pre-test</id>
          <goals><goal>prepare-agent</goal></goals>
        <execution>
        <execution>
          <id>post-test</id>
          <goals><goal>report</goal></goals>
          <configuration>
            <outputDirectory>${project.build.directory}/site/jacoco-ut</outputDirectory>
          </configuration>
        <execution>
        <!--如果有整合測試，也就是有定義 maven-failsafe-plugin ，再加下面兩個<execution> -->
        <execution>
          <id>pre-integration-test</id>
          <goals><goal>prepare-agent-integration</goal></goals>
        <execution>
        <execution>
          <id>report-integration</id>
          <goals><goal>report-integration</goal></goals>
          <configuration>
            <outputDirectory>${project.build.directory}/site/jacoco-it</outputDirectory>
          </configuration>
        <execution>
      </executions>
    </plugin>
  </plugins>
</build>

同樣，報表也需整合進Site Report裡

<pom>
  <reporting>
    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.11</version>
        <configuration>
          <reportSet>
            <id>jacoco-report</id>
            <reports><report>report</report></reports>
          </reportSet>
        </configuration>
      </plugin>
    </plugins>
  </reporting>
</pom>
