导读：我正在尝试使用以下配置在bitbucket平台上运行测试： image: node:6.8.0pipelines: default: - step: script: - echo 'deb http://dl.google.com/linux/chrome/deb/ stable main' /etc/apt/sources.list.d/chrome.list - wget -q -O - https://dl-ssl.google

我正在尝试使用以下配置在bitbucket平台上运行测试：

image: node:6.8.0

pipelines:
  default:
    - step:
        script:
          - echo 'deb http://dl.google.com/linux/chrome/deb/ stable main' > /etc/apt/sources.list.d/chrome.list
          - wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
          - set -x && apt-get update && apt-get install -y xvfb google-chrome-stable
          - ln -sf /usr/bin/xvfb-chrome /usr/bin/google-chrome
          - npm --version
          - npm install
          - npm test

那是输出：

> ng test

问题是业力无法启动Chrome浏览器.我认为任何码头环境都会出现问题.
如何在bitbucket管道中运行测试？

解决方法

尝试将测试切换到PhantomJS.

安装PhantomJS Runner https://github.com/karma-runner/karma-phantomjs-launcher

$npm install –save-dev karma-phantomjs-launcher

编辑你的karma.conf.js以使用PhantomJS

// /karma.conf.js
module.exports = function (config) {
  config.set({
    // ...
    plugins: [
      // ...
      require('karma-phantomjs-launcher'),// ...  
    ],// ...  
    // browsers: ['Chrome'],browsers: ['PhantomJS'],phantomjsLauncher: {
      // Have phantomjs exit if a ResourceError is encountered 
      // (useful if karma exits without killing phantom)
      exitOnResourceError: true // Could require proxy if tests access images without /base path
    },//...
  });
};

现在应该在PhantomJS而不是Chrome中运行测试.

默认测试脚本也运行watch,因此您可能希望将package.json测试脚本修改为“test”：“ng test –watch = false”.如果你想让本地开发运行,只需使用ng test而不是npm test启动.
