Like said in the epic, we do have some arquillian tests already in some modules.

This task is for porting over non-arquillian tests to run with Arquillian.

The service module is a good indicator.

All tests are inheriting from a base class, that is internally leveraging Apache OpenEJB:
https://github.com/aerogear/aerogear-unifiedpush-server/blob/master/service/src/test/java/org/jboss/aerogear/unifiedpush/service/AbstractBaseServiceTest.java

So, part of the task is to

• introduce arquillian dependency
• refactor the base class to make it arquillian enabled (not sure a base class is really needed, since Arquillian has some other way to provide the archives (the current arquillian tests are a good example))
• make sure all tests run fine w/ arquillian
