Continuous integration with karma

[f-jost]

Hi,

What is the best practice to use karma for continuous integration?

Should we use xvfb, selenium?

I found this package npm:
https://www.npmjs.com/package/karma-selenium-webdriver-launcher

but doesn't seem to work :

karma.conf.js
'use strict';

var By = require('selenium-webdriver').By,
    until = require('selenium-webdriver').until,
    firefox = require('selenium-webdriver/firefox');

module.exports = function(config) {
    config.set({
    frameworks: ['jasmine'],

    // define browsers 
    customLaunchers: {
      swd_firefox: {
        base: 'SeleniumWebdriver',
        browserName: 'Firefox',
        getDriver: function(){
          // example from https://www.npmjs.com/package/selenium-webdriver#usage 
          var driver = new firefox.Driver();
          return driver;
        }
      },
    },

browsers: ['swd_firefox']
  });
};

Thanks

EDIT :
npm install xvfb resolved my problem. Then in my karma.conf.js:

module.exports = function(config) {

var Xvfb = require('xvfb');
var xvfb = new Xvfb();
xvfb.startSync();

See #1320 and karma-runner/karma-chrome-launcher#20 (comment).

In the current system you're expected to set up Xvfb before running Karma. E.g. ensure an xvfb deamon is running and run export DISPLAY=.. (with your display number) before invoking karma or npm test.
