未生成jacoco-ut.exec覆盖报告

Question

Java 1.8。 Maven 3.8。我想生成Junit测试的覆盖报告。因此，我在POM.xml

                    <plugin>
                        <groupId>org.jacoco</groupId>
                        <artifactId>jacoco-maven-plugin</artifactId>
                        <version>0.7.4.201502262128</version>
                        <executions>
                            <execution>
                                <id>prepare-ut-agent</id>
                                <phase>process-test-classes</phase>
                                <goals>
                                    <goal>prepare-agent</goal>
                                </goals>
                                <configuration>
                                    <destFile>${project.build.directory}/jacoco-ut.exec</destFile>
                                    <propertyName>jacoco.agent.ut.arg</propertyName>
                                    <append>true</append>
                                </configuration>
                            </execution>
                            <execution>
                                <id>prepare-it-agent</id>
                                <phase>pre-integration-test</phase>
                                <goals>
                                    <goal>prepare-agent</goal>
                                </goals>
                                <configuration>
                                    <destFile>${project.build.directory}/jacoco-it.exec</destFile>
                                    <propertyName>jacoco.agent.it.arg</propertyName>
                                    <append>true</append>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>

开放终端中使用此操作，并以此方式运行测试：

mvn test -Dtest=com.my_company.myproject.ComponentServiceTest

测试成功完成。但是要生成的报道报告。文件jacoco-it.exec在目标文件夹中不存在

Answer 1

pom.xml缺少报告目标，如@rajani-b 。

这是报告目标的配置。

<execution>
  <id>report</id>
  <goals>
    <!--
      Generate coverage reports in xml,csv,html formats
      in folder ${project.build.directory}/site/jacoco
    -->
    <goal>report</goal>
  </goals>
</execution>

以下是jacoco-maven-plugin的完整＆lt; plugin＆gt;供参考。

<plugin>
   <groupId>org.jacoco</groupId>
   <artifactId>jacoco-maven-plugin</artifactId>
   <version>0.7.4.201502262128</version>
   <executions>
      <execution>
         <id>prepare-ut-agent</id>
         <phase>process-test-classes</phase>
         <goals>
            <goal>prepare-agent</goal>
         </goals>
         <configuration>
            <propertyName>jacoco.agent.ut.arg</propertyName>
            <append>true</append>
         </configuration>
      </execution>
      <execution>
         <id>prepare-it-agent</id>
         <phase>pre-integration-test</phase>
         <goals>
            <goal>prepare-agent</goal>
         </goals>
         <configuration>
            <propertyName>jacoco.agent.it.arg</propertyName>
            <append>true</append>
         </configuration>
      </execution>
      <execution>
         <id>prepare-agent</id>
         <goals>
            <goal>prepare-agent</goal>
         </goals>
      </execution>
      <execution>
         <id>report</id>
         <goals>
            <!--
              Generate coverage reports in xml,csv,html formats
              in folder ${project.build.directory}/site/jacoco
            -->
            <goal>report</goal>
         </goals>
      </execution>
   </executions>
</plugin>
