defining current state in unit tests - angularjs

Question

I've moved this 'reports' feature from a single module (called 'aam') into the core, so that other modules (such as 'bbc') can use it.
Now I'm rewriting the unit test(s).
The grunt error I'm getting is
should go state aam.reports with URL_NOT_SPECIFIED
reports-state spec
TypeError: 'null' is not an object
(evaluating 'BbpcConfiguration.getProperty(configProperty).then')
which indicates to me that $state is empty or not structured correctly.
Here is the report controller:
(function() {
'use strict';
angular.module('com.ct.bbpcCore')
.controller('reportController', ['$window', '$state', 'BbpcUserService', 'BbpcConfiguration', function ($window, $state, BbpcUserService,BbpcConfiguration) {
angular.element(document).ready(function () {
//Get url base on locale
var reportUrl = "URL_NOT_SPECIFIED";
var currentState = $state.current.name;
var configProperty = "";
var title = "";
if (currentState.indexOf('aam.reports')) {
configProperty = 'report.aam.link';
title = "AAM.REPORT";
};
if (currentState.indexOf('bbc.reports')) {
configProperty = 'report.bbc.link';
title = "BBC.REPORT";
};
BbpcConfiguration.getProperty(configProperty).then(function(response) {
if (response) {
var language = BbpcUserService.getLanguageCd() || "en_CA";
reportUrl = response[language] || reportUrl;
}
var spec = "width=" + $window.outerWidth + ", height=" + $window.outerHeight;
$window.open(reportUrl, title, spec);
});
});
}]);
}());
And here is report-controller.spec:
describe('reports-state spec', function() {
'use strict';
var $injector, $window, $rootScope,
$state, BbpcConfiguration, reportController, $controller, BbpcUserService;
beforeEach(function() {
module('com.ct.bbpcCore', function($provide) {
$provide.value('BbpcConfiguration', BbpcConfiguration = {
getProperty: function(key){
if('report.aam.link' === key){
return {
"fr_CA": "https://eng-link",
"en_CA": "https://fre-link"
};
}
return null;
}
});
});
inject(function(_$injector_) {
$injector = _$injector_;
$window = $injector.get('$window');
$state = $injector.get('$state');
$rootScope = $injector.get('$rootScope');
$controller =$injector.get('$controller');
BbpcUserService =$injector.get('BbpcUserService');
});
});
it('should go state aam.reports with URL_NOT_SPECIFIED', function() {
$state.current = {'name': 'aam.reports' };
spyOn($window, 'open').andCallFake(function(){});
reportController = $controller('reportController', {'$window':$window, '$state':$state, 'BbpcUserService':BbpcUserService, 'reportLink':undefined});
$state.go('aam.reports');
$rootScope.$apply();
expect($state.current.name).toEqual('aam.reports');
expect($window.open).toHaveBeenCalledWith('URL_NOT_SPECIFIED', 'AAM.REPORT', 'width=0, height=0');
});
});
I tried simply adding the line $state.current = {'name': 'aam.reports' }; in the 'it' block, but that's not what it's looking for.
Not sure how to debug unit tests. :P I can't use a console.log($state) to peek into it.
