Angularjs “错误”;“预期功能”;模拟localStorage.getItem时
我试图模拟对localStorage.getItem的调用,但得到错误“预期函数”。以下是我的测试代码:Angularjs “错误”;“预期功能”;模拟localStorage.getItem时,angularjs,unit-testing,mocking,jasmine,Angularjs,Unit Testing,Mocking,Jasmine,我试图模拟对localStorage.getItem的调用,但得到错误“预期函数”。以下是我的测试代码: describe("AuthService Tests", function() { var authSvc, httpBackend, scope; var fakeItem = "{\"access_token\":\"giant_access_token\",\"token_type\":\"bearer\",\"expires_in\":1209599,\".issued\":
describe("AuthService Tests", function() {

beforeEach(inject(function (_AuthService_, $q, $rootScope, $httpBackend, $state, _config_, _messages_) {

httpBackend = $httpBackend;
}));
describe('Test suite 1', function () {
it('should return true if user is Administrator', function () {
var result = authSvc.isAdministrator(); // error here
expect(result).toBe(true);
});
});
});
测试中的服务:
(function () {
'use strict';
angular
.module('app.services')
.factory('AuthService', AuthService);
AuthService.$inject = ['$q', '$rootScope', '$http', '$state', 'config', 'messages'];
function AuthService($q, $rootScope, $http, $state, config, messages) {
var userIdKey = 'userId';
var tokenKey = 'tokenKey';
var userAuthKey = 'userAuth';
var svc = {
isAdministrator: isAdministrator
};
return svc;
function isAdministrator() {
var item = localStorage.getItem(tokenKey); // eror here
var jsonparse = JSON.parse(item);
return jsonparse.accountType == 'Administrator';
}
})();
当我运行测试时,我的模拟函数returnFakeToken甚至没有被调用,我得到了错误(发生错误的代码行用注释标记):
TypeError:需要函数
我做错了什么
谢谢 您不需要监视
localStorage
。它是作为HTML5标准的一部分内置到浏览器中的一个功能。您应该测试的是您的服务是否返回预期值。此外,如果您在PhantomJS中进行测试,您可能需要模拟localStorage
。实际上,我不是在浏览器中运行测试,而是在cordva应用程序中运行测试,但是,是的,您是对的,没有必要模拟localStorage。非常感谢。科尔多瓦正在为你模拟一个浏览器。很酷,它能做到,嗯?
