【问题描述】:
我有一个角度服务类:-
angular.module('triggerTips')
.service('userData', function ($rootScope, $http, $log, $firebase) {
this._log = {
service : 'userData'
};
// Synchronized objects storing the user data
var config;
var userState;
// Loads the user data from firebase
this.init = function(readyCallback) {
var log = angular.extend({}, this._log);
log.funct = 'init';
var fireRef = new Firebase('https://XYZfirebaseio.com/' + $rootScope.clientName);
config = $firebase(fireRef.child('config')).$asObject();
userState = $firebase(fireRef.child('userState').child($rootScope.userName)).$asObject();
Promise.all([config.$loaded(), userState.$loaded()]).
then(
function() {
if(config == null || Object.keys(config).length < 4) {
log.message = 'Invalid config';
$log.error(log);
return;
}
if(!userState.userProperties) {
userState.userProperties = {};
}
if(!userState.contentProperties) {
userState.contentProperties = {};
}
log.message = 'User Properties: ' + JSON.stringify(userState.userProperties);
$log.debug(log);
log.message = 'Content Properties: ' + JSON.stringify(userState.contentProperties);
$log.debug(log);
log.message = 'Loaded user data from firebase';
$log.debug(log);
readyCallback();
},
function() {
log.message = 'Unable to load user data from firebase';
$log.error(log);
}
);
};
// Returns the initial tip configuration
this.getConfig = function() {
return config;
};
// Set the value of a user property
// A user property is something about the user himself
this.setUserProperty = function(property, value) {
if(!userState.userProperties) {
userState.userProperties = {};
}
userState.userProperties[property] = value;
userState.$save();
$rootScope.$broadcast('user-property-change', property);
};
// Get the value of a user property
this.getUserProperty = function(property) {
if(userState.userProperties) {
return userState.userProperties[property];
}
};
// Set the value of a user content property
// A content property is something about a particular peice of content for a particular user
this.setContentProperty = function(contentName, property, value) {
if(!userState.contentProperties[contentName]) {
userState.contentProperties[contentName] = {};
}
userState.contentProperties[contentName][property] = value;
userState.$save();
$rootScope.$broadcast('content-property-change', contentName, property);
};
// Increment a count property on the user state for a given tip
this.incrementContentProperty = function(contentName, property) {
if(!userState.contentProperties[contentName]) {
userState.contentProperties[contentName] = {};
}
if(!userState.contentProperties[contentName][property]) {
userState.contentProperties[contentName][property] = 0;
}
userState.contentProperties[contentName][property]++;
userState.$save();
$rootScope.$broadcast('content-property-change', contentName, property);
};
// Returns the user state for a given tip and property
this.getContentProperty = function(contentName, property) {
if(userState.contentProperties) {
var t = userState.contentProperties[contentName];
if(t) {
return t[property];
}
}
};
});
我正在尝试使用 jasmine 对该服务进行单元测试:-
我的单元测试是:-
'use strict';
describe('Service: userData', function () {
// load the service's module
beforeEach(function() {
module('triggerTips');
});
// instantiate service
var userData;
beforeEach(inject(function (_userData_) {
userData = _userData_;
}));
it('should load correctly', function () {
expect(!!userData).toBe(true);
});
describe('after being initialized', function () {
beforeEach(function(done) {
// Unable to get this working because the callback is never called
userData.init(function() {
done();
});
jasmine.DEFAULT_TIMEOUT_INTERVAL = 2000;
});
it('should have a valid config', function (done) {
setTimeout(function() {
expect(Object.keys(userData.getConfig()).length == 0);
done();
}, 1500);}); }); });
我阅读了有关 Jasmine 中的异步支持的信息,但由于我对使用 JavaScript 进行单元测试比较陌生,因此无法使其工作。
我收到一个错误:
在指定的超时时间内未调用异步回调 jasmine.DEFAULT_TIMEOUT_INTERVAL
有人可以帮我提供我的代码的工作示例和一些解释吗?
【问题讨论】:
-
readyCallback 在 promise 被解决时被调用。您需要解决承诺并触发摘要,请参阅docs.angularjs.org/api/ng/service/…
-
感谢您的回复,我如何在不更改服务的情况下进行更正,请帮我解决这个问题
-
您不需要更改源代码。您应该对 config 和 userState 使用模拟,并在其 $loaded 函数上返回已解决的承诺,然后在您的测试中调用 $scope.$apply。如果你用你的代码设置一个小提琴,我可以在那里展示它。
-
littel 明白你的意思,你能帮我做一个测试用例吗?这对我很有帮助
-
尝试删除'done'参数。受 [this question][1] 启发的答案。 [1]:stackoverflow.com/questions/22604644/…
