我有以下 Controller ViewMeetingCtrl.js
(function () {
'use strict';
angular.module('MyApp').controller('ViewMeetingCtrl', ViewMeetingCtrl);
ViewMeetingCtrl.$inject = ['$scope', '$state', '$http', '$translate', 'notificationService', 'meetingService', '$modal', 'meeting', 'attachmentService'];
function ViewMeetingCtrl($scope, $state, $http, $translate, notificationService, meetingService, $modal, meeting, attachmentService) {
$scope.meeting = meeting;
$scope.cancelMeeting = cancelMeeting;
function cancelMeeting(meetingId, companyId) {
meetingService.sendCancelNotices(companyId, meetingId)
.success(function () {
$state.go('company.view');
});
}
}
})();
我能够成功调用 的 spyOn取消 session ()但不是通过 的召唤发送取消通知 方法。我想做的是,我想在任何时候测试 取消 session ()被调用,它调用 发送取消通知() 方法 。我知道我应该使用 createSpy 方法来执行此操作。但我不知道该怎么做。
下面是测试用例 ViewMeetingCtrlSpec.js
describe('ViewMeetingCtrl CreateSpy --> Spying --> cancelMeeting', function () {
var $rootScope, scope, $controller , $q ;
var sendCancelNoticesSpy = jasmine.createSpy('sendCancelNoticesSpy');
beforeEach(angular.mock.module('MyApp'));
beforeEach(inject(function ($rootScope, $controller ) {
scope = $rootScope.$new();
createController = function() {
return $controller('ViewMeetingCtrl', {
$scope: scope,
meeting : {}
});
};
var controller = new createController();
}));
it("tracks that the cancelMeeting spy was called", function() {
//some assertion
});
});
最佳答案
describe('ViewMeetingCtrl', function () {
var scope, meetingService;
beforeEach(angular.mock.module('MyApp'));
beforeEach(inject(function ($rootScope, $controller, _meetingService_) {
scope = $rootScope.$new();
meetingService = _meetingService_;
$controller('ViewMeetingCtrl', {
$scope: scope,
meeting : {}
});
}));
it('should send cancel notices whan cancelMeeting is called', function() {
var fakeHttpPromise = {
success: function() {}
};
spyOn(meetingService, 'sendCancelNotices').andReturn(fakeHttpPromise);
scope.cancelMeeting('foo', 'bar');
expect(meetingService.sendCancelNotices).toHaveBeenCalledWith('bar', 'foo');
});
});
我鼓励您停止依赖从服务返回的 HTTP promise 。相反,只需考虑服务返回一个 promise 。这些更容易模拟,并且当您不再返回 HTTP promise 时,不会强制您重写 Controller 代码。
在您的 Controller 中:
function cancelMeeting(meetingId, companyId) {
meetingService.sendCancelNotices(companyId, meetingId)
.then(function () {
$state.go('company.view');
});
}
在您的测试中:
var fakePromise = $q.when();
spyOn(meetingService, 'sendCancelNotices')and.returnValue(fakePromise);
scope.cancelMeeting('foo', 'bar');
expect(meetingService.sendCancelNotices).toHaveBeenCalledWith('bar', 'foo');
