karma-xvfb-chrome-launcher

Launcher for Google Chrome, Google Chrome Canary and Google Chromium, using Xvfb. Blatantly copied from karma-xvfb-chrome-launcher.

Installation

The easiest way is to keep karma-xvfb-chrome-launcher as a devDependency in your package.json, by running

$ npm install karma-xvfb-chrome-launcher --save-dev

Configuration

// karma.conf.js
module.exports = function(config) {
  config.set({
    browsers: ['Chrome', 'Chrome_without_security'], // You may use 'ChromeCanary' or 'Chromium' as well

    // you can define custom flags
    customLaunchers: {
      Chrome_without_security: {
        base: 'Chrome',
        flags: ['--disable-web-security']
      }
    }
  })
}

The --user-data-dir is set to a temporary directory but can be overridden on a custom launcher as shown below. One reason to do this is to have a permanent Chrome user data directory inside the project directory to be able to install plugins there (e.g. JetBrains IDE Support plugin).

customLaunchers: {
  Chrome_with_debugging: {
    base: 'Chrome',
    chromeDataDir: path.resolve(__dirname, '.chrome')
  }
}

You can pass list of browsers as a CLI argument too:

$ karma start --browsers Chrome,Chrome_without_security
