protractor.config.js file:

const path = require('path');

exports.config = {
  directConnect: true,
  baseUrl: 'https://www.google.com',

  capabilities: {
    browserName:'chrome'
  },

  framework: 'custom',

  frameworkPath: require.resolve('protractor-cucumber-framework'),
  // frameworkPath: require.resolve('serenity-js'),

  specs: [
    './e2e/features/*.feature'
  ],

  cucumberOpts: {

    compiler: 'ts:ts-node/register',
    require: [
      "./e2e/features/step_definitions/*_step.ts",
      // path.resolve(process.cwd(), './e2e/step_definitions/Test_step.ts')
    ],
    tags: '@Test',
    strict: false,
    format: ["pretty", "json:report/json/cucumber_report.json"],
    dryRun: false,
  },

  onPrepare: function () {
    project: "./e2e/tsconfig.e2e.json";
    browser.driver.manage().window().maximize();
  }
};

I've tried the suggestion in stackoverflow but it didn't worked for me.

• Cucumber version: 3.0.6
• Node version: 8.2.1
• Protractor version: 5.2.0

ts-node将需要安装，因为黄瓜require要这样做。

npm install ts-node
