Question

我只是尝试从Protractor- Cucumber测试设置开始，以下是我的基本设置，我在网上跟随一些教程就做了。感谢撒玛利亚人分享了这一点。

问题是当我尝试运行它时，出现错误-导入的意外令牌。我不知道为什么会这样。非常感谢您的帮助。

以下是我正在使用的node等版本-

C:\Users\A>npm --version
6.4.1

C:\Users\A>node --version
v10.15.1

C:\Users\A>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，我遇到了以下错误-

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';

这些导入应在量角器初始化时自动完成。
