How to configure Protractor to use Cucumber

Question

As of 0.20.1 Cucumber is now fully supported in Protractor but I\'m battling to find any documentation on how to configure it properly. Any idea how you would setup world.js?

Answer 1

I've gotten good milage from this setup

  class ChtWorld
    chai = require('chai');
    chaiAsPromised = require('chai-as-promised');

    constructor:  ->
      @browser = @protractor = require('protractor').getInstance()
      @By = @protractor.By
      chai.use(chaiAsPromised)
      @expect= chai.expect


  module.exports= ->
    this.World= (callback) ->
      w = new ChtWorld()
      callback(w)

Since protractor is already setup, just getting a reference to it is sufficient (note that for Cucumber to correctly load up the new world, the modules.exports has to be just right).

As a side note, this is located in features/support/world.coffee, and not explicitly added to the 'requires' list (trying to do that got me into Gherkin Lexing error problems).
