您好，我正在尝试为名为 daterangecontroller 的 Controller 编写一些代码，该 Controller 调用服务为其提供一些开始日期和结束日期的值(这些是日历小部件的一部分)。
日期范围服务提供开始和结束日期的默认值。然后 Controller 监视开始和结束日期模型的更改。当发生更改时，它会调用该服务来更新日期范围间隔，最终由另一个服务调用。
如果错误显示以下内容，我很难理解为什么此条件会失败:
Chrome 35.0.1916 (Mac OS X 10.9.2) Controller: dateRangeCtrl default start date loads as 8 days ago FAILED
Expected Date(Wed Jun 11 2014 11:04:11 GMT-0700 (PDT)) to be Date(Wed Jun 11 2014 11:04:11 GMT-0700 (PDT)).
Error: Expected Date(Wed Jun 11 2014 11:04:11 GMT-0700 (PDT)) to be Date(Wed Jun 11 2014 11:04:11 GMT-0700 (PDT)).
at null.<anonymous> (/Users/test/client/spec/controllers/dateRangeTest.js:32:28)
这是我的代码的相关部分。
Controller :
angular.module("vizApp").controller("DaterangeCtrl", function ($rootScope, $scope, DateRangeService) {
"use strict";
// Dates to fill in the calendar widget
var dates_current_interval = DateRangeService.giveCurrentInterval();
var dates_array = dates_current_interval.split("/");
$scope.startDate = new Date(dates_array[0]);
$scope.endDate = new Date (dates_array[1]);
var dateRange = {};
// this model watches for changes in the "from" calendar section
$scope.$watch("startDate", function (newVal, oldVal, scope) {
if (newVal !== oldVal && newVal !== null && $scope.startDate) {
dateRange.start = new Date($scope.startDate);
dateRange.end = new Date($scope.endDate);
return DateRangeService.updateDateInterval(dateRange);
}
});
// this model watches for changes in the "to" calendar section
$scope.$watch("endDate", function (newVal, oldVal, scope) {
if (newVal !== oldVal && newVal !== null && $scope.startDate) {
dateRange.start = new Date($scope.startDate);
dateRange.end = new Date($scope.endDate);
return DateRangeService.updateDateInterval(dateRange);
}
});
});
还有服务
angular.module("vizApp").factory("DateRangeService", [ "$rootScope", function () {
"use strict";
return{
dateInterval: null,
/**
*
* @param : none
* returns either a default to fill in the input boxes or the updated dateInterval
*
*/
giveCurrentInterval: function giveCurrentInterval(){
if (this.dateInterval === null){
var startDate = new Date();
startDate.setDate(startDate.getDate() - 8);
var endDate = new Date();
var dateFill = startDate.toISOString() + "/" + endDate.toISOString();
return dateFill;
}
else{
return this.dateInterval;
}
},
/**
*
* @param dateRange : the date range passed in from the model being watched
* returns the new dateInterval
*
*
*/
updateDateInterval: function updateDateInterval(dateRange){
this.dateInterval = dateRange.start.toISOString() + "/" + dateRange.end.toISOString();
return this.dateInterval;
}
};
}]);
更新:这是 Jasmine 代码
"use strict";
describe("Controller: dateRangeCtrl", function () {
var scope, DateRangeController, httpBackend;
//load the controller's module
beforeEach(module('vizApp'));
beforeEach(function () {
angular.mock.inject(function ($injector) {
httpBackend = $injector.get("$httpBackend");
});
});
//initialize the controller and a mock scope
beforeEach(inject(function($controller, $rootScope) {
// create a new child scope
scope = $rootScope.$new();
//create a new instance of date range controller
DateRangeController = $controller('DaterangeCtrl', { $scope : scope });
}));
it('default start date loads as 8 days ago', function(){
var mockStartDate = new Date();
mockStartDate.setDate(mockStartDate.getDate() - 8);
httpBackend.expectGET('partials/landing.html');
httpBackend.whenGET('partials/landing.html').respond(200);
expect(scope.startDate).toBe(mockStartDate);
});
it('changes date range when start date is changed', function(){
var mockStartDate2 = new Date();
mockStartDate2.setDate(mockStartDate2.getDate() - 10);
httpBackend.expectGET('partials/landing.html');
httpBackend.whenGET('partials/landing.html').respond(200);
scope.$apply(function () {
scope.startDate = mockStartDate2;
});
expect(scope.startDate).toBe(mockStartDate2);
});
});
最佳答案
使用 toEqual()，而不是 toBe()，toEqual 检查等价性，toBe 检查它们是否是完全相同的对象。
如果您有大量测试，这可能会非常慢，我建议将其分开。
