测试服务时无法在服务中注入$ q

Question

(function (angular) {
    'use strict';
    var testingModule= angular.module('testingModule', []); 
testingModule.factory('testService', [ '$q',
        function ($q) {
            var service = {
                    get: null
                },
                tokenDeferred = $q.defer(),

            service.getDataWithPromise = function () {

                        tokenDeferred.resolve({token: this.token, isAuthenticated: true});
                    } 
                });

                return tokenDeferred.promise;
            };
})(angular)

当我尝试为这种情况编写单元测试时，它总是给我$ $ undefined，Any idea什么可能出错？

Ius注入的方式如下：

   beforeEach(inject(function ($q_, _testService_) {
    q = $q
        fmOauthAccessTokenService = _testService_;

        scope = $rootScope.$new();

    }));

Answer 1

应该是这样的（请注意$q周围的双下划线）：

beforeEach(inject(function (_$q_, _testService_) {
    q = _$q_;
        fmOauthAccessTokenService = _testService_;

        scope = $rootScope.$new();

    }));
