Karma - Chrome失败2次(无法启动).放弃

Question

我一直在尝试使用karma-chrome-launcher运行我的测试,但每次运行我的测试时都会抛出此错误:

INFO [启动器]:启动浏览器Chrome错误[启动器]:无法启动Chrome

INFO [launcher]: Trying to start Chrome again (1/2).
ERROR [launcher]: Cannot start Chrome

INFO [launcher]: Trying to start Chrome again (2/2).
ERROR [launcher]: Cannot start Chrome

ERROR [launcher]: Chrome failed 2 times (cannot start). Giving up.

这是我的karma.conf.js代码:

// Karma configuration

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: 'www',

    ],

    exclude: [

    ],

    // enable / disable colors in the output (reporters and logs)
    colors: true,


    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,


    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,


    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['PhantomJS'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false
  });
};

我在这里安装模块:https://www.npmjs.com/package/karma-chrome-launcher

谢谢!

Answer 1

我遇到了同样的问题并尝试了很多我发现的建议解决方案,但最终解决它的是删除node_modules文件夹并通过npm install获取所有新内容

Answer 2

我的构建环境也有同样的问题。

我所做的是按照 Rafael Cichocki 的建议启用调试：

logLevel: config.LOG_DEBUG

然后尝试使用与调试输出中可见的完全相同的行启动 chrome 浏览器。

原来 chrome 浏览器由于缺少 ttf 字体而崩溃。所以运行：

apt-get install ttf-freefont

为我解决了这个问题，karma 开始推出 chrome。

Answer 3

在 中Karma.conf.js，将超时增加到 60000

captureTimeout: 60000,
browserDisconnectTimeout: 60000,
browserDisconnectTolerance: 3,
browserNoActivityTimeout: 60000,
