Intro

Problem: I learned how to run RSpec to test classes and modules in my gem. But, if I wanted to test my gem as if it were already included in a Rails app, I couldn't find much info about it online.

I usually do unit tests with RSpec, and I test the whole stack with Cucumber. So here we will just setup Cucumber to run the Rails app that you embed in your gem.

Before we begin:

• This tutorial is for people who already know how to make gems, and who have used RSpec and Cucumber before in a Rails app.
• MyGem and my_gem below refer to the name of the gem we are creating. Replace this with your own name.

//     Backbone.Rails.js
//
//     Makes Backbone.js play nicely with the default Rails setup, i.e.,
//     no need to set
//       ActiveRecord::Base.include_root_in_json = false
//     and build all of your models directly from `params` rather than
//     `params[:model]`.
//
//     Load this file after backbone.js and before your application JS.

PaginatedCollection = Backbone.Collection.extend({
  initialize: function() {
    _.bindAll(this, 'parse', 'url', 'pageInfo', 'nextPage', 'previousPage');
    this.page = 1;
  },
  fetch: function(options) {
    options || (options = {});
    this.trigger("fetching");

# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!

export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "

# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!

# Switched to branch "master"
# ~/code/web:master$ git checkout beta_directory
