Angular 单元测试 Jasmine Spy 错误

Question

以下控制器收到 TypeError：“未定义”不是函数（正在评估 sessionService.getCurrentPlace()）。我有一个模拟服务，该方法被监视。模拟服务上的另一种方法工作正常。我在间谍上尝试过.AndReturns({..}) 以及.AndCallThrough()，但没有运气。知道我错过了什么，还是我要解决这个问题？非常感谢！

控制器：

    'use strict';

angular.module('wallyApp')
    .controller('addGatewayCtrl', function ($scope, $location, $filter, sessionService) {
        /*
            private members
        */
        //set scope from session data
        $scope.processSession = function (places) {
            $scope.currentPlaceId = sessionService.getCurrentPlace();
            if (!$scope.currentPlaceId) {
                $scope.currentPlaceId = places[0].id;
            }
            $scope.place = $filter("getById")(places, $scope.currentPlaceId);
            $scope.ready = true;
        };

        /* 
            setup our scope
        */
        $scope.currentPlaceId = null;
        $scope.place = {};
        $scope.videoSrc = "/videos/gateway-poster.gif";
        $scope.loaded = true;

        /*
            setup controller behaivors
        */

        //set video or gif to show or hide video
        $scope.setVideo = function () {
            $scope.videoSrc = "/videos/gateway.gif";
        };
        $scope.setPoster = function () {
            $scope.videoSrc = "/videos/gateway-poster.gif";
        };
        //initialize scope
        $scope.setVideo();

        //submit form
        $scope.continue = function () {
            $location.path("/setup/pair-gateway");
            return false;
        };
        //cancel
        $scope.back = function () {
            $location.path("/setup/plan-locations");
            return false;
        };
        //wifi
        $scope.gotoWifi = function () {
            $location.path("/setup/wifi");
            return false;
        };


        /*
            setup our services, etc
        */
        //get our places from the cache
        sessionService.get("places").then(function (places) {
            if (!places || places.length < 1) {
                sessionService.refreshPlaces(); //Note we don't care about the promise as our broadcast watch will pick up when ready
            } else {
                $scope.processSession(places);
            }
        }).catch(function (error) {
            //TODO:SSW Call Alert Service??
        });

        //Watch broadcast for changes
        $scope.$on("draco.placesRefreshed", function (event, data) {
            sessionService.get("places").then(function (places) {
                $scope.processSession(places);
            });
        });
    });

所以我想通了。使用嵌套延迟，您必须在两者之间调用 $scope.$apply()。以下修复了它（以及对模拟数据响应的一些小的更改，但这些都是微不足道的）：

        //resolve promises
        activityMessagesDeferred.resolve(mockActivityMessages);
        $rootScope.$apply();
        $rootScope.$broadcast("draco.sessionRefreshed");
        activityCountDeferred.resolve(mockActivityCount);
        $rootScope.$apply();

        placesDeferred.resolve(mockPlaces);
        activityListDeferred.resolve(mockActivities);
        $rootScope.$apply();
