We need to prove we can measure coverage for a given project by combining coverage db from various test projects.
Our structure goes as follows:
None of this projects share a parent pom, nor can they.
This is what I've tried:
//instrument project-src-x binaries $ project-src-x: mvn clean clover:setup install //run project-it-y tests $ project-it-y: mvn clean clover:setup -Dmaven.clover.cloverDatabase=/tmp/clover-y.db //run project-ut-z tests $ project-ut-z: mvn clean clover:setup -Dmaven.clover.cloverDatabase=/tmp/clover-z.db //merge clover dbs and generate report $ project-src-x : mvn clean clover:merge -Dmaven.clover.merge.basedir=/tmp/ clover:clover
The resulting report has no information about project-src-x at all.
I know both test projects are using the instrumented code of project-src-x because I needed to include clover's jar in order to execute them.
What can be the problem here?
Thanks in advance,
$ project-src-x: mvn clean clover:setup install
Where do you write clover.db file for this project? As you run clover:merge with -Dmaven.clover.merge.basedir=/tmp, then I assume that for project-src-x you should write clover.db to /tmp as well. And the most probably you write it to standard location (<project-src-x dir>/target/clover).
Please try to run:
mvn clean clover:setup install -Dmaven.clover.cloverDatabase=/tmp/clover.db
