Chai expect - expect(browser.getTitle()) 错误 - browser.getTitle 不是函数

Question

我有以下使用 Chai 的代码，但是当执行失败并且控制台 returns "TypeError: browser.getTitle is not a function." 我通往 Globals.js 的路径是正确的，因为如果我这样做，它会起作用 - expect('Test abc').toContain('abc')。请帮忙。

const Globals = require('../utilities/Globals');
const browser = require('protractor');
const { Given } = require('cucumber');

// Chai
const globals = new Globals();
const expect = globals.expect;


Given('I am on google page with title {string}', function (title) {
    return expect(browser.getTitle()).to.eventually.equal(title);
});

这是Globals.js-

const chai = require('chai');
const chaiAsPromised = require('chai-as-promised');

class Globals {
    constructor() {
        this.expect = chai.expect;
        chai.use(chaiAsPromised);
    }
}

module.exports = Globals;

Answer 1

browser是全局变量，可以直接使用，不需要。因此下面一行是不必要的：

const browser = require('protractor');

Chai expect - expect(browser.getTitle()) 错误 - browser.getTitle 不是函数

Chai expect - expect(browser.getTitle()) errors with - browser.getTitle is not a function

javascript

protractor

chai

cucumberjs
