Question

我正在尝试使用Chrome的新无头浏览器模式在Travis ci上运行角度测试，但在使用npm run e2e（ng e2e）运行我的量角器e2e测试时遇到错误。使用npm test（ng test --watch=false）运行我的单元测试工作正常。

Travis Config：

sudo: false
dist: trusty

language: node_js
node_js:
  - '6.11'

addons:
  chrome: stable

install:
  - npm install -g @angular/cli
  - npm install

script:
  - npm test
  - npm run e2e

notifications:
  webhooks:
    on_success: change
    on_failure: always
    on_start: false

量角器配置：

const { SpecReporter } = require('jasmine-spec-reporter');

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  capabilities: {
    browserName: 'chrome',
    chromeOptions: {
      args: ['--headless', '--disable-gpu', '--window-size=800x600']
    }
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};

Travis错误

谷歌浏览器的沙盒模式是一个问题，阻止了Chrome创建会话。

你需要禁用它。

示例量角器配置：

const { SpecReporter } = require('jasmine-spec-reporter');

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  capabilities: {
    'browserName': 'chrome',
    chromeOptions: {
      args: ['--headless', '--disable-gpu', '--window-size=800,600', '--no-sandbox']
    }
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};
