SyntaxError:尝试在 e2e 测试中导入量角器时出现意外的令牌导入

问题描述

我已经编写了一个 Angular 4 应用程序，现在我正在尝试使用 Protractor 运行一些基于 e2e 的测试.

I've written an angular 4 app and now I'm trying to run some e2e based tests using Protractor.

我错过了什么吗?

尝试运行测试脚本时出错:

Error when trying to run test script:

[rob@work repo]$ npm run e2e

> [email protected] e2e /home/rob/git/repo
> protractor protractor.config.js

量角器.config.js

protractor.config.js

exports.config = {
  framework: 'jasmine',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  multiCapabilities: [{
    'browserName': 'chrome'
  }],
  specs: ['test/e2e/**/*.ts'],
  mochaOpts: {
    reporter: 'spec',
    slow: 5000,
    timeout: 5000
  }
};

e2e 测试文件(app.ui.test.ts):

e2e test file (app.ui.test.ts):

'use strict';
import { browser } from 'protractor';
const HOST_URL = 'http://localhost:1344';

describe('hello world', function() {

  describe('hello world app', function() {
    const FULL_URL = HOST_URL + '/';
    it('should greet', function() {
      browser.get(FULL_URL);
    });
  });
});

目录结构:

├── protractor.config.js
├── test
│   └── e2e
│       └── app.ui.test.ts

推荐答案

您首先需要在运行之前转译您的 *.ts-文件，就像您处理应用源文件一样.

You first need to transpile your *.ts-files before running, just like you do with your app source files.
