Unit Testing dependency injection

Question

I am brand new to jasmine and karma. I believe I have the environment setup properly and I am able to run very basic unit tests, but as soon as I try to instantiate a controlle

As you are including the $state dependency in your controller - you need to provide the $state in the controller unit test.

    var $scope = $rootScope.$new(),
    ctrl = $controller('Home', {
               $scope: $scope,
               $state: {} //Or inject the state using the injector service and then you can use some jasmine spies to mock the function calls or just to spy on 'em.
          });
    expect(ctrl).not.toBe(null);

Your it block with the changes....

it('should create "phones" model with 3 phones', inject(function($controller, $rootScope, $state) {

    /*
     * 
     * COMMENTING OUT THESE LINES = PASS
     *
     */
        var scope = $rootScope.$new(),
            ctrl = $controller('Home', {$scope:scope, $state: $state});
        expect(ctrl).not.toBe(null);
    }));

However at the setup of my unit tests I like to create function for controller setup as I describe in this setup here.
