I have refactored Core integration tests to separated source folder: src/test/integration.
By default, build does not run those tests,
you can run them using (the JBoss AS 7 (Mojarra) integration will be tested):
$ mvn verify -Dintegration=jbossas
Additionally, you can run following configuration to test integration with TomEE (MyFaces)
$ mvn verify -Dintegration=tomee
Note that TomEE 1.0.0 have to be started (managed container still does not exists: RF-12363).
To skip unit tests and run just integration tests, you can use -DskipTests=true
$ mvn verify -Dintegration=jbossas -DskipTests=true
