Deleted the AdvertisementHelperTest
Geen idee wat hier mis gaat -.-
Merge branch 'master' of https://github.com/Vipeax/Wetzelplaats.git
Removed all 'helper' classes. Removed then because they are not mandatory anymore. 

Thought that you had to mock all the interfaces. Instead, I added setters to the existing facade classes for EntityManager and just mocked all the entity managers. Works like a charm!
