Test coverage missing in Netbeans 8.1?

I downloaded recently Netbeans 8.1 here

I chose second option: "Java EE".

But I can't find how to run test coverage for my unit tests. I have this menu:

It's a Maven Web Application.

When I go to Tools -> Plugins and search for "coverage", I have this:

I installed it and restarted the IDE, I saw it was installing the plugin but there's no change in my menu. If I search "coverage" in the Installed plugins, nothing shows up else than the one I just installed... I thought Netbeans had it implemented? I also thought Netbeans has the Maven test coverage as well...

I read that the plugin I installed (TikiOne JaCoCoverage) is just an extension of the already existing Netbeans Test Coverage.. so that would explain why I can't see it.

How can I enable test coverage?

Thanks.
