javascript - 不确定 AngularJS 单元测试中的错误

Question

我正在尝试在 AngularJs 中对 Controller 进行单元测试，并且遵循 AngularJs 文档作为指南。 https://docs.angularjs.org/guide/controller

在指南中(在上面的链接中)，他们在 Controller 中有此代码

$scope.spice = "habanero";

以及测试中的这段代码

it('should set the default value of spice', function() {
      expect($scope.spice).toBe('habanero');
    });

在我正在测试的 Controller 中，有一些如下代码:

$scope.sessionViewModel = session;

在我的测试中我写了这个:

it('should set the default value of sessionViewModel', function(){
            expect($scope.sessionViewModel).toBe(session);
        });

但我收到一条错误消息 TypeError 无法读取未定义的属性“sessionViewModel”

不太确定我做错了什么

整个测试文件:

describe('forgotPasswordCtrl function', function() {

    describe('forgotPasswordCtrl', function(){
    var $scope;
    var returnMsg = 'Forgot password response message';
    var returnMsgTwo = '/web/tfgm_customer';

    beforeEach(module('forgotPasswordApp'));


    beforeEach(inject(function($rootScope, $controller){
        $scope = $rootScope.$new();
        $controller = ('ForgotPasswordCtrl', {$scope: $scope});
            }));


        it('returns a -forgot password response- message', function(){
            expect($scope.globalError).toEqual(returnMsg);
        });

        it('assigns a url depending on a customer match happens', function(){
            expect(window.location.assign).toEqual(returnMsgTwo);
            });

        it('should set the default value of sessionViewModel', function(){
            expect($scope.sessionViewModel).toBe(session);
        });
      });
    });

尝试改变

    $controller = ('ForgotPasswordCtrl', {$scope: $scope});

至

    controller = $controller('ForgotPasswordCtrl', {$scope: $scope});
