我有以下控制器的 ViewMeetingCtrl.js

（函数（）{    使用严格的;    angular.module（'MyApp的'）控制器（'ViewMeetingCtrl'，ViewMeetingCtrl）。    。ViewMeetingCtrl $注='$范围，$状态，$ HTTP，$翻译'，'notificationService'，'meetingService'，'$模式，会议，attachmentService'];    功能ViewMeetingCtrl（$范围，$状态，$ HTTP，$翻译，notificationService，meetingService，$莫代尔，会议attachmentService）{        $ scope.meeting =会议;        $ scope.cancelMeeting = cancelMeeting;        功能cancelMeeting（meetingId，companyId）{            meetingService.sendCancelNotices（companyId，meetingId）                .success（函数（）{                    $ state.go（'company.view'）;                }）;        }    }}）（）;

我能够succussfully调用spyOn对于 cancelMeeting（）而与 sendCancelNotices 方法的调用。我想要做的是，我想测试，只要 cancelMeeting（）被调用时，它调用的 sendCancelNotices（）方式。我知道我应该createSpy方法去做到这一点。但我不知道该怎么做。

下面是测试案例ViewMeetingCtrlSpec.js

描述（'ViewMeetingCtrl CreateSpy - ＆GT;刺探 - ＆GT; cancelMeeting'，函数（）{        变量$ rootScope，范围，$控制器，$ Q;        变种sendCancelNoticesSpy = jasmine.createSpy（'sendCancelNoticesSpy'）;        beforeEach（angular.mock.module（'的MyApp'））;        beforeEach（注（函数（$ rootScope，$控制器）{            范围= $ rootScope $新的（）。            createController =功能（）{                返回$控制器（'ViewMeetingCtrl'，{                $适用范围：适用范围，                会议：{}                }）;            };            VAR控制器=新createController（）;        }））;        它（跟踪该cancelMeeting间谍被称为功能（）{            //一些断言        }）;}）;

解决方案

描述（'ViewMeetingCtrl'，函数（）{    VAR范围，meetingService;    beforeEach（angular.mock.module（'的MyApp'））;    beforeEach（注（函数（$ rootScope，$控制器，_meetingService_）{        范围= $ rootScope $新的（）。        meetingService = _meetingService_;        $控制器（'ViewMeetingCtrl'，{            $适用范围：适用范围，            会议：{}        }）;    }））;    它（'应该发送取消通知焕cancelMeeting被称为'，函数（）{        VAR fakeHttpPromise = {            成功：函数（）{}        };        spyOn（meetingService，'sendCancelNotices'）andReturn（fakeHttpPromise）。        scope.cancelMeeting（'富'，'棒'）;        期待（meetingService.sendCancelNotices）.toHaveBeenCalledWith（'巴'，'富'）;    }）;}）;

我会鼓励你停止HTTP承诺依靠从服务返回。相反，只考虑服务返回的承诺。这些都是易于模拟，并不会强迫你重写你的控制器code，当你不返回HTTP的诺言了。

在你的控制器：

函数cancelMeeting（meetingId，companyId）{        meetingService.sendCancelNotices（companyId，meetingId）            。然后（函数（）{                $ state.go（'company.view'）;            }）;    }

在您的测试：

VAR fakePromise = $ q.when（）;        spyOn（meetingService，'sendCancelNotices'）and.returnValue（fakePromise）;        scope.cancelMeeting（'富'，'棒'）;        期待（meetingService.sendCancelNotices）.toHaveBeenCalledWith（'巴'，'富'）;

I have the following 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'); }); } } })();

I was able to succussfully invoke the spyOn for cancelMeeting() but not with the calling of sendCancelNotices method. What i want to do is , i want to test that whenever cancelMeeting() gets called , it calls sendCancelNotices() method . I know that i should go with createSpy method to do this . But i am not sure how to do it .

Below is the test case 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 }); });

解决方案

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'); }); });

I would encourage you to stop relying of HTTP promises being returned from services. Instead, just consider the service returns a promise. Those are easier to mock, and won't force you to rewrite your controller code when you don't return HTTP promises anymore.

In your controller:

function cancelMeeting(meetingId, companyId) { meetingService.sendCancelNotices(companyId, meetingId) .then(function () { $state.go('company.view'); }); }

In your test:

var fakePromise = $q.when(); spyOn(meetingService, 'sendCancelNotices')and.returnValue(fakePromise); scope.cancelMeeting('foo', 'bar'); expect(meetingService.sendCancelNotices).toHaveBeenCalledWith('bar', 'foo');
