This is the world.coffee file used at Axisto Media for an application in current development. It demonstrates how to boot a selenium server just once, make it available to your step definitions, and kill it once all of your cucumber.js feature have finished running.
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
