量角器-cucumberjs：browser.get（）不工作

Question

当我用量角器运行cucumber时，我收到错误信息，任何人都可以帮助我提出原因：

'use strict';

( function () {

var navigate = function () {
    browser.get( 'http://store.demoqa.com/products-page/your-account/' );
};

var login = function ( username, password ) {
    this.username.sendKeys( username );
    this.password.sendKeys( password );
    this.loginButton.click();
};

var LoginPage = function () {
    this.username     = dv.findElement( by.id( 'log' ) );
    this.password     = dv.findElement( by.id( 'pwd' ) );
    this.loginButton  = dv.findElement( by.id( 'login' ) );
};

LoginPage.prototype.navigate = navigate;
LoginPage.prototype.login    = login;

module.exports = LoginPage;

} )();

'use strict';

var LoginPage      = require( '../login/loginpage.js' );

var HomePage       = require( '../../features/homepage/homepage.js' );

var chai           = require( '../../chai' );

var chaiAsPromised = require( '../../chai-as-promised' );

chai.use( chaiAsPromised );

var expect = chai.expect;

module.exports = function () {

var loginPage;
var homePage;

this.Before( function ( callback ) {
    loginPage = new LoginPage();
    homePage  = new HomePage();
    isAngularSite(false);
    loginPage.navigate();
    callback();

} );

this.After( function ( callback ) {
    //logout
    callback();
} );

// First Scenario
//this.When('I am in login page')

this.Given(/^I login using valid creadentials$/, function ( callback ) {

    loginPage.login( 'username', 'password' ); //valid creadential
    callback();
} );

this.Then(/^I should be logged in$/, function ( callback ) {
    expect(homePage.homeIndicator).toEqual('http://someUrl.com/#home');
    callback();
} );

};

-----------------config.js---------------

'use strict';

var config = {

seleniumAddress : 'http://localhost:4444/wd/hub',
specs           : [ 'features/login/login.feature' ],
baseUrl         : 'http://store.demoqa.com/',
capabilities    : {
browserName : 'firefox'
},

onPrepare   : function () {
var width  = 1024;
var height = 600;

global.dv = browser.driver;

dv.manage().window().setSize( width, height );

// This will tell the Protractor not to wait for angular
global.isAngularSite = function(flag) {
    browser.ignoreSynchronization = !flag;
};
},

framework : 'cucumber',

cucumberOpts : {
// define your step definitions in this file
require : 'features/login/spec.js',
//format  : 'pretty'
}

};

exports.config = config;

----------login.feature------------

Feature: Login

As a user, I should be able to have login creadentials so that I can login to    the system

Scenario: Valid login creadentials

Given I login using valid creadentials

Then I should be logged in

Answer 1

原因是我忘记在loginpage.js的set函数中添加括号。替换

LoginPage.prototype.navigate = navigate;
LoginPage.prototype.login    = login;

由：

LoginPage.prototype.navigate = navigate();
LoginPage.prototype.login    = login();
