为什么$ injector：modulerr错误，当我运行我的testing与业力？

什么会导致这个错误？

Error: [$injector:modulerr] Failed to instantiate module fooApp due to: TypeError: 'undefined' is not a function (evaluating '$stateProvider .state') 

编辑post+++

 inject(function ($injector) { MyService= $injector.get('MyService'); }); 

MyService = undefined为什么？

编辑post—

我的服务（提供商）：

 'use strict'; angular.module('fooApp') .factory('MyService', function () { var function1 = function function1(value) { return value; }; return { function1: function1 }; }); 

我的testing：

 'use strict'; describe('Service: MyService', function () { beforeEach(module('fooApp')); var MyService; beforeEach(function(){ inject(function ($injector) { MyService= $injector.get('MyService'); }); }); it('should ....', function(){ expect(MyService.function1('....')).toEqual(...); ..... }); ...... }); 

foo.js：

 'use strict'; angular.module('fooApp') .config(function ($stateProvider) { $stateProvider .state('foo', { url: '/foo', views: { 'content': { templateUrl: 'app/foo/foo.html', controller: 'FooCtrl' }, 'footer': { templateUrl: 'components/footer/footer.html', line 15: controller: 'FooterCtrl' } } }); });
