Running code coverage with Cobertura and Jacoco

问题


I have a bit of a problem getting code coverage reports for both Integration Tests and Unit Tests in Sonar for a Maven Plugin project (which uses invoker plugin for the integration tests).

I can't use the default Jacoco coverage tool for the unit tests, as these use Powermock, which results in 0% coverage for classes using that. On the other hand, I can't find a reliable way to get results for the Groovy-based integration tests without using Jacoco.

So what I need is for Cobertura to produce a Unit Test report, Jacoco to produce an Integration Test report, and for Sonar to be able to read the lot.

I tried using the example here https://github.com/Godin/sonar-experiments/tree/master/jacoco-examples/maven-invoker-plugin-example but eliminating the executions bound to the test phase, but I then get a unit test coverage of '-' in Sonar. I think the reason for this is that to get this method to work, I need to speicify Jacoco as the core coverage tool for Sonar.

Any ideas on a way round this? My pom.xml follows:

Since you've configure the sonar as

 <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
 <sonar.jacoco.itReportPath>
     ${project.basedir}/target/jacoco-t.exec
 </sonar.jacoco.itReportPath>

This means you are telling sonar to reuse the existing report from sonar.jacoco.itReportPath. If there is no existing report, there is no any coverage.

In may case, I use the cobertura and reuse its report from maven site generation. as the following configuration properties: -

<sonar.java.coveragePlugin>cobertura</sonar.java.coveragePlugin>
<sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
<sonar.surefire.reportsPath>
    ${project.build.directory}/surefire-reports
</sonar.surefire.reportsPath>
<sonar.cobertura.reportPath>
    ${project.build.directory}/site/cobertura/coverage.xml
</sonar.cobertura.reportPath>

I can get the reuse by using the following command :-

mvn clean install site sonar:sonar

I can reproduce your issue by using the following command :-

mvn clean install sonar:sonar

The coverage is 0%. Since there is no existing report at the report path.

Then please make sure that there is a report named "jacoco-t.exec" as specified before executing the sonar.

Since I'm not familiar with the JaCoCo and do not know which maven phase that produces thae report file. I would suggest to execute the command like the following:-

mvn clean test sonar:sonar

or

mvn clean install sonar:sonar

or the same as mine

mvn clean install site sonar:sonar

I hope this may help.
