javascript - 尝试将页面对象与 Protractor 一起使用时出现“对象不是函数”错误

Question

每次尝试运行测试时，我都会遇到TypeError: object is not a function。在我开始使用 PageObject 之前一切正常。

这是我的spec.js

'use strict';

var todoAppPage = require('../pages/angular.page');

describe('angularjs todo list', function () {

    var page;

    beforeEach(function () {
        page = new todoAppPage();
        page.get();
    });

    it('should add a todo task', function () {
        page.addNewTask('my first task');

        expect(page.todoList.count()).toEqual(1);
        expect(page.todoList.get(0).getText()).toEqual('my first task'); 
    });
});

这是页面对象文件

'use strict';

var todoAppPage = function() {

    this.newTodo = element(by.model('newTodo'));
    this.todoList = element.all(by.repeater('todo in todos'));

    this.get = function() {
        browser.get('/');
    };

    this.addNewTask = function (taskName) {
        this.newTodo.sendKeys(taskName);
        this.newTodo.sendKeys(protractor.Key.ENTER);
    };
};

module.exports = new todoAppPage();

“导出”页面对象的方式有问题，应该是:

module.exports = todoAppPage;
