AngularJS error - entering $ location throws an error

So this is driving me crazy, when I try to type $location

into one of my tests, I get the following error:

TypeError: undefined is not a function

karma.conf.js:

module.exports = function (config) {
    config.set({

        // base path that will be used to resolve all patterns (eg. files, exclude)
        basePath: '../',

        // list of files / patterns to load in the browser

        ],


        // list of files to exclude
        exclude: [
            '**/*.swp'
        ],

        logLevel: config.LOG_INFO,

        autoWatch: false,

        browsers: ['PhantomJS'],


        // Continuous Integration mode
        // if true, Karma captures browsers, runs the tests and exits
        singleRun: true
    });
};

      

        
        
        
      

    

Controller:

angular.module('ecQDesktopApp')
    .controller('DashboardCtrl', function ($scope, $window) {

        $scope.goToURL = function (url) {
            $window.location = url;
        }

    }
);

      

        
        
        
      

    

Function File Spec:

describe('Unit: Testing Dashboard Controller', function() {
    'use strict';

    var scope, window;

    beforeEach(module('ecQDesktopApp'));

    beforeEach(inject(function($rootScope, _$window_, $controller) {
        scope = $rootScope.$new();
        window = {
            location: ""
        };
        $controller('DashboardCtrl', {$scope: scope, $window: window});
    }));

    it('goes to Url', function() {
        var url = "testUrl";
        scope.goToURL(url);
        expect(window.location).toBe("testUrl");
    });
}); 

      

        
        
        
      

    

But if I change beforeEach(inject(function($rootScope, _$window_, $controller)

to beforeEach(inject(function($rootScope, _$window_, $controller, $location)

, I get an error.

It's weird, it looks like I can inject any AngularJS services, but whenever I try to use $ location in any of my tests, I get this failure.

Thanks in advance.
