Unit testing with karma

[AlexanderBielen]

Hello,

I need some help/advice since I am stuck on a problem with unit testing my AppComponent. This is the component containing the notification-bar. I cannot seem to get my unit tests for this component working because of something that has to do with this plugin.

If I import the NotificationBarModule in my tests I get this error : Cannot read property 'unsubscribe' of undefined.

If I import only the NotificationBarComponent i get this error : No provider for NotificationBarService.
And I can't seem to provide the NotificationBarService (I tried a lot of things).

I am not sure if the problem is on my end or not, but if you have some working unit tests could you perhaps help me out? I could provide more information if you need it.

Thanks,
Alexander
