So here's the thing. I've been investigating many threads but couldn't find anything related to my error. I'm trying to test my angular app, (I want to clarify first that I'm kinda newbie to unitTesting)
According to this tutorial I've set everything up and basic tests work fine. But when I include the NgMock module, my real angular app and write a simple test to test a method on one of my controllers I get the following stackTrace.

Warning: Task "karma:dev" failed. Use --force to continue.
Aborted due to warnings.
It seems like the "mock" scope that ngMock generates doesn't accept to have listeners or something like that.
Does anybody have a hint of could be wrong here?
I could paste all my configuration files but I think that's too much info and I dont want to flood the post. Let me know if any other info is needed and I'll add it.
Thanks in advanced!

It's hard to say without looking at your exact setup, but did you create a scope object to inject into your controller?
A lot of the time, you can fake it just by using the $rootScope object:
beforeEach(angular.mock.inject($injector => {
$controller = $injector.get('$controller');
rootScope = $injector.get('$rootScope');
}));
... test code ...
let controller = $controller('UserController', {$scope: rootScope});
... do stuff with controller ...
However, you can also use rootScope to create a new scope and feed that in.
