我正在尝试通过使用 karma-jasmine 和 httpBackend 模拟服务层来编写我的第一个控制器测试。但我收到了这个错误。

错误：意外请求：GET./webresources/campaign/getCampaignDetails/undefined 预期 GET ./webresources/campaign/getCampaignDetails/CMP1000004568

在此先感谢您的帮助:)

服务：

    (function() {
    'use strict';

    angular.module('tbApp').factory('Campaign', CampaignFactory);

    CampaignFactory.inject = ['$http'];


    function CampaignFactory($http) {

        //base url for all rest service calls
        var baseUrl = WS_PATH + '/webresources/campaign';

        var Campaign = {

            getCampaignDetails: getCampaignDetails,

        };

        return Campaign;

        function getCampaignDetails(campaignId) {
            return $http.get(baseUrl + '/getCampaignDetails/' + campaignId).then(getCampaignDetailsComplete);

            function getCampaignDetailsComplete(response) {
                return response.data;
            }
        }

         }
})();

控制器：

(function () {
'use strict';

angular.module('tbApp').controller('campaignEditCtrl', campaignEditCtrl);


campaignEditCtrl.inject = ['$routeParams', 'Campaign', 'User', '$location', 'Asset', '$window', '$scope', '$compile', 'ImageLibrary', 'Lists'];

function campaignEditCtrl($routeParams, Campaign, User, $location, Asset, $window, $scope, $compile, ImageLibrary, Lists) {


    var vm = this;

    vm.campaignData = [];
    vm.getCampaignDetails = getCampaignDetails;


    initialise();

    /**
     * Initialises the campaign properties page         
     */
    function initialise() {
        // Registes a click listener to hide action menu
        $window.addEventListener('click', function (event) {
            if (event.which !== 3) {
                $scope.$apply(function () {
                    vm.selectedActionItem = '';
                });
            }
        });
         fromPage=true;
         fromPage1=true;

        vm.user = User.info;
        vm.campaignId = $routeParams.campId;
        //set default value to prevent filter error
        vm.campaignData.imageName = '///////';
        getCampaignDetails();
        getAllImageData();
    }

    /**
     * Load the campaign details         
     */
    function getCampaignDetails() {
        vm.loadingCampaignDetails = true;
        Campaign.getCampaignDetails(vm.campaignId).then(getCampaignDetailsComplete);

        function getCampaignDetailsComplete(data) {

            vm.campaignData = data;                

        }
    }

     }})();

控制器规格：

    describe('campaignEditCtrl as vm', function() {
    var scope, httpBackend,  controller,  vm, createController, campaignId;

    var baseUrl = './webresources/campaign';

     beforeEach(module("tbApp"));
    beforeEach(inject(function($rootScope, $httpBackend, $controller) {
        httpBackend = $httpBackend;

        scope = $rootScope.$new();
        controller = $controller;
        campaignId= "CMP1000004568";
        //service = Campaign;
        createController = function() {
            return $controller('campaignEditCtrl', {
                '$scope': scope
            });
        };

        httpBackend.when("GET", baseUrl+"/getCampaignDetails/"+campaignId).respond([{}, {}, {}]);


    }));

  /*afterEach(function() {
        httpBackend.verifyNoOutstandingExpectation();
        httpBackend.verifyNoOutstandingRequest();
    });*/


    it('should run the Test to get the campaign data from the backend', function() {
        console.log("here"+campaignId);
        vm=createController();
        httpBackend.expectGET(baseUrl+"/getCampaignDetails/"+campaignId);

        scope.$apply(function() {
            scope.runTest();
        });

        //expect(vm.campaignData.imageName).toEqual('///////');

        httpBackend.flush();

        expect(vm.campaignData.length).toBe(3);


    });
});

我们可以在 karma 输出中看到测试失败，因为 URL 错误。而不是广告系列 ID，您将获得未定义。

Chrome 41.0.2272 (Windows 7) campaignEditCtrl as vm should run the Test to get the campaign data from the backend FAILED
        Error: Unexpected request: GET ./webresources/campaign/getCampaignDetails/undefined
        Expected GET ./webresources/campaign/getCampaignDetails/CMP1000004568

看起来您正在尝试测试您的getCampaignDetails()函数，该函数vm.campaignId作为参数传递给您的服务调用。vm.campaignId但是，在您的测试中，您在调用函数之前没有设置任何内容。

在您的测试设置中，我会尝试将您的代码更改为：

    scope = $rootScope.$new();
    controller = $controller;
    campaignId= "CMP1000004568";
    //service = Campaign;
    createController = function() {
        var controller = $controller('campaignEditCtrl', {
            '$scope': scope
        });
        scope.vm.campaignId = campaignId;
        return controller;
    };

...看看是否可以解决它。

这里发生的是你的getCampaignDetails()函数的行为取决于你的控制器的状态。您的控制器具有initialize()使您的控制器进入getCampaignDetails()可以成功的状态的功能。但是，在您的测试中，您不会执行类似的初始化。
