testing ui-router stateprovider 'resolve:' values - angular-ui-router

Question

I'm using jasmine+karma to run the following code...
and get the following error:
Expected { then : Function, catch : Function, finally : Function } to equal 123.
Can someone help me understand why I don't get a resolved value for my promise. thanks
'use strict';
angular
.module('example', ['ui.router'])
.config(function($stateProvider) {
$stateProvider
.state('stateOne', {
url: '/stateOne',
resolve: {cb: function($q) {
var deferred = $q.defer();
deferred.resolve(123);
return deferred.promise;
}},
controller: function($scope, cb) {console.log(' * in controller', cb);},
templateUrl: 'stateOne.html'
});
})
.run(function($templateCache) {
$templateCache.put('stateOne.html', 'This is the content of the template');
});
describe('main tests', function() {
beforeEach(function() {module('example');});
describe('basic test', function($rootScope) {
it('stateOne', inject(function($rootScope, $state, $injector, $compile) {
var config = $state.get('stateOne');
expect(config.url).toEqual('/stateOne');
$compile('<div ui-view/>')($rootScope);
$rootScope.$digest();
expect($injector.invoke(config.resolve.cb)).toEqual(123);
}));
});
});

Ok, Figured it out with some help (via email) from Nikas, whose blog I found at:
http://nikas.praninskas.com/angular/2014/09/27/unit-testing-ui-router-configuration/.
Here is a succinct example that demonstrates how to test the resolve values in ui.router, where the values involve $http.
angular
.module('example', ['ui.router'])
.factory('Clipboard', function($http) {
return {
get: function(args) {
return $http.get('/db/clipboard');
}
};
})
.config(function($stateProvider) {
$stateProvider
.state('stateOne', {
resolve: {cb: function(Clipboard) {
return Clipboard.get();
}}
});
});
describe('main tests', function() {
beforeEach(function() {module('example');});
it('stateOne', inject(function($state, $injector, $httpBackend) {
$httpBackend.whenGET('/db/clipboard').respond({a:1});
$injector.invoke($state.get('stateOne').resolve['cb'])
.then(function(res) {console.log(' *res ', res.data);})
.catch(function(err) {console.log(' *err ', err);});
$httpBackend.flush();
}));
afterEach(inject(function($httpBackend) {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
}));
});
