Konacha, Mocha, BackboneJS and Ruby on Rails configuration - ruby-on-rails

Question

I am using Konacha to test a BackboneJS application in my Ruby on Rails application. I have read about every tutorial on the web and it shows how easy it is to set up and get working. Unfortunately, I am not having this level of success. Here is what I have:
app/assets/javascripts/app_specific/itapp/models/post.js
Itapp.Models.Post = Backbone.Model.extend({
isFirstPost: function() {
return (this.get('id') === Itapp.bootstrap.posts[0].get('id'));
},
});
spec/javascripts/app_specific/itapp/models/post_spec.js
//= require spec_helper
var expect = chai.expect;
describe("Posts", function() {
it("should have a first post", function() {
//just trying anything to get some kind of valid error/issue
//I could put anything here and it wouldn't matter, just FYI
expect(typeof this.isFirstPost).to.equal('function');
});
});
spec/javascripts/spec_helper.js file:
// Require the appropriate asset-pipeline files:
//= require application
//Any other testing specific code here...
//Custom matchers, etc....
Konacha.mochaOptions.ignoreLeaks = true
beforeEach(function() {
return window.page = $("#konacha");
});
// set the Mocha test interface
// see http://mochajs.org/#interfaces
mocha.ui('bdd');
//
// ignore the following globals during leak detection
mocha.globals(['YUI']);
//
// or, ignore all leaks
mocha.ignoreLeaks();
//
// set slow test timeout in ms
mocha.timeout(5);
//
// Show stack trace on failing assertion.
chai.config.includeStack = true;
I do have a config/initializers/konacha.rb file:
Konacha.configure do |config|
config.spec_dir = "spec/javascripts"
config.spec_matcher = /_spec\.|_test\./
config.stylesheets = %w(application)
config.driver = :selenium
end if defined?(Konacha)
The error I am getting:
Error: Failed to load app_specific/itapp/collections/posts_spec.js.
Perhaps it failed to compile? Check the rake output for errors.
Checking the rake output:
ActionView::Template::Error: couldn't find file 'application' which I am requiring in my spec_helper.js
So for some reason even though in my spec_helper I am trying to load the BackboneJS application for the testing environment it is not able to find it.
Any thoughts/ideas that I should try to get this communicating/working?

Answer 1

I figured this out. The problem was that it was not finding the file under app/assets/javascripts/ correctly. I needed to do this at the top of the spec/javascripts/app_specific/itapp/models/post_spec.js file:
//= require app_specific/itapp/models/post
Once I did that it was able to find the associated code that I am testing against. I will need to work a bit more to clean up the path in a spec_helper.js file, but I am no longer blocked on this.
