Play test coverage & sonar

[Aurélien Allienne]

Hi,

Is it possible to see code coverage with sonar?

Regards

[Marcos Pereira]

Yes.

Using Jacoco4sbt[1] you can measure code coverage in a format compatible with Emma and then integrate it with Sonar.

Wow, I would be very interesting in getting test coverage reports also in Play 2.x. Is this plugin supposed to work with 2.0.1 (yes, we are stuck on an old version for now) ?

I get this error when I tried following the instructions,

Hi, try to use an older version of jacoco4sbt. I think that 1.2.2 is compatible with sbt 0.11.2 and scala 2.9.1

Hi,

I have the same problem.

I was able to run some test coverage with the jacoco-plugin. It seems pretty straightforward.

But I had the problem that the sonar runner didn't pick up the coverage.

I also created a small mixed scala/java sbt project. The java files get picked up. But if I switch the sonar runner to scala, there is nothing to see.

I may put an example on github if anyone is interested.

Greetings,

Martin

Hi Martin,

I am interested, I have the same issue with Sonar not picking up the coverage.

Best,

Roch

I also have issues with Sonar and would love to see a working example.

I've posted this issue here already:

https://groups.google.com/forum/?fromgroups=#!searchin/play-framework/sonar/play-framework/cgs_d6e8T3I/1Sj9JwEJDiAJ

I believe the issue is with the generated jacoco.exec file.

Thanks

Peter

After some time, I start to test jacoco4sbt.

I use http://ics-software-engineering.github.io/play-example-quality-assurance/ as reference. But now, I have this error

 $ jacoco:test
[error] (jacoco:full-classpath) java.lang.IncompatibleClassChangeError: class org.jacoco.core.internal.flow.ClassProbesVisitor has interface org.objectweb.asm.ClassVisitor as super class

The link above mentionned this.

Note: Due to ASM library incompatibilities (?), you cannot install both Jacoco and PMD.  If you do, then Jacoco
will report the following error:

But I don't add pmd module.

Do you have any idea of the problem ?
