javascript - Angular 服务 Jasmine 测试找不到 $http

Question

按照这里的教程:http://www.benlesh.com/2013/06/angular-js-unit-testing-services.html 下面的 jasmine 测试应该有效——但没有。我已将测试简化为最简单的测试。与我链接的示例测试不同，我无法让它通过。知道我做错了什么吗？

被测服务:

var appServices = angular.module('MyApp.services', ['$http', '$rootScope']);
  appServices.factory('Auth', ['$http', '$rootScope', function ($http, $rootScope) {

    var accessLevels = routingConfig.accessLevels,
        userRoles = routingConfig.userRoles,
        currentUser = { username: '', role: userRoles.public };

    function changeUser(user) {
        angular.extend(currentUser, user);
    }

    return {
        authorize: function (accessLevel, role) {
            if (role === undefined) {
                role = currentUser.role;
            }
            return accessLevel.bitMask & role.bitMask;
        },
        isLoggedIn: function (user) {
            if (user === undefined) {
                user = currentUser;
            }
            return user.role.title === userRoles.user.title;
        },
        login: function (user, success, error) { //ignore jslint
            user.role = userRoles.user;
            changeUser(user);
            $rootScope.$broadcast('login');
            success(user);
        },
        logout: function (success, error) { //ignore jslint
            changeUser({
                username: '',
                password: '',
                role: userRoles.public
            });
            success();
        },
        accessLevels: accessLevels,
        userRoles: userRoles,
        user: currentUser
    };
}]);

测试:

describe('services tests', function () {

    beforeEach(function () {
        module('MyApp.services');

        // get your service, also get $httpBackend
        // $httpBackend will be a mock, thanks to angular-mocks.js
        inject(function (_Auth_, $httpBackend) {
            Auth = _Auth_;
            httpBackend = $httpBackend;
        });
    });
    it('should have an authorize function', function () {
        expect(angular.isFunction(Auth.authorize)).toBe(true);
    });

});

Answer 1

var appServices = angular.module('MyApp.services', ['$http', '$rootScope']);

应该是

var appServices = angular.module('MyApp.services', []);

$http 和 $rootScope 不是模块，所以错误是 appServices 找不到 $http 模块.
