语法错误:意外的令牌 { - 运行量角器黄瓜测试时出错

Question

我只是想从量角器开始 - 黄瓜测试设置，以下是我按照在线一些教程进行的基本设置。感谢分享这一点的撒玛利亚人。

问题是当我尝试运行它时，我收到错误 - 导入的意外令牌。我不知道为什么它会给出这个。任何帮助都非常感谢。

以下是我正在使用的节点等版本 -

C:UsersA>npm --version
6.4.1
C:UsersA>node --version
v10.15.1
C:UsersA>protractor --version
Version 5.4.2

以下是我的功能文件 -

Feature: Go to the home
Display the title
Scenario: Home Page
Given I am on the home page
When I do nothing
Then I should see the title

以下是我的步骤定义文件 -

import { AppPage } from '../pages/app.po';
import { Before, Given, When, Then } from 'cucumber';
import { expect } from 'chai';
let page: AppPage;
Before(() => {
page = new AppPage();
});
Given(/^I am on the home page$/, async () => {
await page.navigateTo();
});
When(/^I do nothing$/, () => {});
Then(/^I should see the title$/, async () => {
expect(await page.getTitleText()).to.equal('Welcome to angular-cli-cucumber-demo!');
});

以下是我的页面对象文件 -

import { browser, by, element } from 'protractor';
export class AppPage {
navigateTo() {
return browser.get('/');
}
getTitleText() {
return element(by.css('app-root h1')).getText();
}
}

当我尝试使用命令ng e2e运行测试时，我得到以下错误 -

Answer 1

将以下部分添加到您的protractor.conf.js

onPrepare() {
require('ts-node').register({
project: require('path').join(__dirname, './tsconfig.json')
});
}

Answer 2

尝试删除

步骤定义

import { Before, Given, When, Then } from 'cucumber';
import { expect } from 'chai';

和页面对象

import { browser, by, element } from 'protractor';

这些导入应由量角器在初始化时自动完成。
