需要另一双眼睛来调试 angular 单元测试

Question

我在单元测试中收到了一系列错误消息，并且已经有几个小时没有取得任何进展。如果有人有时间看一下，将不胜感激。这是一个更大的控制器的一部分，所以如果有人想查看更多代码，请告诉我，但我认为这应该涵盖它。

我得到的错误是：

1)

Test 'CampaginLinksController getCampaignLinks():is loading' failed
        Expected undefined to be true.

2)

Test 'CampaginLinksController getCampaignLinks():has a webSiteId that is not 0 and a buyRequestId that is not "" ' failed
    Expected spy mockCampaginLinkSrv.getWebSiteBuyRequestLinks to have been called with [ 54, 8, 432, 200, { nextRowKey : 'fdsf2', nextPartitionKey : '5432gee' } ] but it was never called.

CampaginLinksCtrlSpec.js

describe('CampaignLinksController', function () {

//make module avalible to tests
beforeEach(module('pb.campaignLinks.controllers'));
beforeEach(module('ui.router'));
beforeEach(module('ui.bootstrap'));

var $controller;
var mockPromiseObj;
var length = 200;
var continuationToken = {
    nextRowKey: 'fdsf2',
    nextPartitionKey: '5432gee'
};

var mockCampaignLinkService = {
    //all but delete must return a promiseObj
    getCampaignLinks: jasmine.createSpy('mockCampaignLinkService.getCampaignLinks').and.returnValue(mockPromiseObj),
    getCampaignBuyRequestLinks: jasmine.createSpy('mockCampaignLinkService.getCampaignBuyRequestLinks').and.returnValue(mockPromiseObj),
    getWebSiteBuyRequestLinks: jasmine.createSpy('mockCampaignLinkService.getWebSiteBuyRequestLinks').and.returnValue(mockPromiseObj),

};

        then: function (orgId, entityId) {

            defer.resolve(this.account);
            return defer.promise;

    }

                    if ($scope.campaignLinks) {
                        $scope.campaignLinks.continuationToken = data.continuationToken;
                        $scope.campaignLinks.total += data.total;
                        $.each(data.items, function (index) {
                            $scope.campaignLinks.items.push(data.items[index]);
                        });
                    } else {
                        // Otherwise add loaded list to scope
                        $scope.campaignLinks = data;

Answer 1

第一次测试：当你初始化mockCampaignLinks时，你应该给它一个对象，而不是true。另外，你可能应该在 beforeEach 中初始化它，因为你在测试中改变了它。

第二个测试：getCampaignBuyRequestLinks 是被调用的方法。
