Using quarkus-jacoco for test that aren't annotated with @QuarkusTest

Question

According to Quarkus Documentation, to have JaCoCo considering test classes that aren't annotated with @QuarkusTest, the only thing we need to do is to configure the jacoco plugin to execute the goal prepare-agent.

I've added that, the same as the documentation suggests:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco.version}</version>
    <executions>
      <execution>
        <id>prepare-agent</id>
        <goals>
          <goal>prepare-agent</goal>
        </goals>
        <configuration>
          <exclClassLoaders>*QuarkusClassLoader</exclClassLoaders>
          <destFile>${project.build.directory}/jacoco-quarkus.exec</destFile>
          <append>true</append>
        </configuration>
      </execution>
    </executions>
  </plugin>

Although, my unit tests haven't been taken into count.

My quarkus version is 2.10.3.Final and the jacoco plugin is set for 0.8.8.

I'm using jupiter 5.8.2 for the unit tests.

Thanks

As the documentation says, this setup only works if at least one @QuarkusTest is run. the jacoco standard setup might solve your problem. in the maven build log you can read two line like this:

[INFO] --- jacoco-maven-plugin:0.8.8:report (jacoco-report) @ project-name ---
[INFO] Skipping JaCoCo execution due to missing execution data file.

The standard jacoco configuration:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco.version}</version>
    <executions>
      <execution>
        <id>prepare-agent</id>
        <goals>
          <goal>prepare-agent</goal>
        </goals>
        <configuration>
          <destFile>${project.build.directory}/jacoco-quarkus.exec</destFile>
          <append>true</append>
        </configuration>
      </execution>
    </executions>
  </plugin>

NOTE: With the standard configuration tests annotated with @QuarkusTest are not managed by the jacoco plugin
