Analyzing code coverage with the Maven JaCoCo plugin


JaCoCo is a free Java code coverage tool. This is essentially the successor to Emma, and it has been developed by the EclEmma team as an Eclipse project.

JaCoCo offers line and branch coverage.

Getting ready

Maven is set up on your system and is verified to work. To do this, refer to the first three recipes of Chapter1, Getting Started.

How to do it...

Use the following steps to analyze the code coverage with the Maven JaCoCo plugin:

  1. Open the pom file of a project that has unit tests (for instance, project-with-tests).

  2. Add the following code:

    <plugin>
      <groupId>org.jacoco</groupId>
      <artifactId>jacoco-maven-plugin</artifactId>
      <version>0.7.2.201409121644</version>
      <executions>
         <execution>
           <id>default-prepare-agent</id>
           <goals>
             <goal>prepare-agent</goal>
           </goals>
         </execution>
         <execution>
         ...
