@climboid a few thoughts...

1. instead of injecting the $injector then manually looking up the service and rootscope you can inject those directly in the beforeEach beforeEach(inject(function($rootScope, $controller, genericService) {..

2. If there a service called genericService in your app called client what you have should work. Is it maybe called GenericService?

3. You don't need to inject genericService at all. Since you are passing what angular provides you directly into the controller just omit that line and angular will do the right thing.

   var createController = function() {
     return $controller('OffersCtrl', {
       $scope: $scope
     });
   };
   

4. Lastly you don't need to return anything in your createController function. The controller is created with the scope as a side-effect and you can now read and write on the scope to test the controller.
