Feature: step definition snippets custom syntax

  As a developer writing my step definitions in another JS dialect
  I want to be able to see step definition snippets in the language I perfer

  Background:
    Given a file named "features/undefined.feature" with:
      """
      Feature: a feature

      """
    And a file named "coffeescript_syntax.js" with:
