Ember Konacha generators for Rails

Generators to help setup an ember-rails app with konacha testing.

PS: Still young and under development... Please help improve it :)


This gem has the stated goal of making it easy to setup a good testing infrastructure for testing your Ember-Rails apps.

An install generator is included for initial infrastructure setup!

Configures your Ember app with Konacha using a Javascript driver (poltergeist for PhantomJS by default). Adds the basic Konacha infrastructure so you can start writing tests/specs.

Can generate Konacha spec-skeletons for:

  • models
  • controllers
  • views
  • helpers

Please help provide more skeleton generators or improve the existing ones!!! :)

More generators

You can find more generators/scaffolders as part of ember-tools

ember-i18n-rails or here. Includes generators to configure and manage i18n with Ember and Rails.

Other Ember-Rails tools


Add this line to your application's Gemfile:

gem 'ember-konacha-rails', github: 'kristianmandrup/ember-konacha-rails'

And then execute:

$ bundle

Or install it yourself (from rubygems) as:

$ gem install ember-konacha-rails

To see if the generators are installed:

$ rails g

Note: or use $ bundle exec rails g (to execute in context of current bundled environment)





Install basic Konacha infrastructure

$ rails g ember_konacha:install

Files that should be generated




Run examples

Clean run (default settings)

$ rails g ember_konacha:install gemfile konacha gemfile poltergeist create spec/javascripts/spec_helper.js.coffee create spec/javascripts/support/konacha_config.js.coffee create spec/javascripts/support/sinon_mvc_mocks.js Trying to download sinon.js (http://sinonjs.org/releases/sinon-1.6.js) ...
vendor assets/javascripts/sinon.js create spec/javascripts/app/store_spec.js.coffee create spec/javascripts/app/router_spec.js.coffee gsub app/assets/javascripts/application.js.coffee

append app/assets/javascripts/application.js.coffee

Note: poltergeist requires you have installed PhantomJS headless JS driver.

via Homebrew:

brew install phantomjs


sudo port install phantomjs

See https://github.com/jonleighton/poltergeist

Install generator was run previously

$ rails g ember_konacha:install
   identical  spec/javascripts/spec_helper.js.coffee
   identical  spec/javascripts/support/konacha_config.js.coffee
   identical  spec/javascripts/support/sinon_mvc_mocks.js
   identical  spec/javascripts/app/store_spec.js.coffee
   identical  spec/javascripts/app/router_spec.js.coffee
        gsub  app/assets/javascripts/application.js.coffee
      append  app/assets/javascripts/application.js.coffee

Now run Konacha!

$ bundle exec rake konacha:run

See more run options at https://github.com/jfirebaugh/konacha

Note: make sure that the following is at the end of your application.js.coffee file:

window.App = Ember.Application.create LOG_TRANSITIONS: true

# Defer App readiness until it should be advanced for either
# testing or production.

(or similar for pure javascript)

The basic test setup/configuration can be found in support/koncha_config.js.coffee and spec_helper.js.coffee files.

The spec_helper initializes the app explicitly using App.advanceReadiness() within Ember.run in the beforeEach closure. To run your app in the browser, while also allowing for testing, you need to explicitly call App.advanceReadiness() when your DOM is ready.

To see install options, run:

$ rails g ember_konacha:install --help

Note: To avoid having to bundle exec install the gem in your current system gem repository, using gem install ember_konacha (when this is an official gem!).

Guard Koncha config generator

To setup your project with Guard and execute koncha specs whenever your javascript assets change (default driver: poltergeist)

$ rails g ember_konacha:guard

To specify a specific js driver (selenium or webkit):

$ rails g ember_konacha:guard --driver wekbkit

Generate Controller spec

Use the --type or -t option to specify type of controller (will try to auto-determine otherwise)

$ rails g ember_konacha:controller_spec login -t base


$ rails g ember_konacha:controller User --type object


$ rails g ember_konacha:controller_spec Users -t array


$ rails g ember_konacha:controller_spec Users

Will autodetect that users is a plural form of user and assume you have an array (resource) controller.

$ rails g ember_konacha:helper_spec persons 

Will generate an object controller, since persons is not a valid plural form!

Generate Model spec

$ rails g ember_konacha:model_spec user


Generate View spec

$ bundle exec rails g ember_konacha:view_spec NewUser


Generate Helper spec

$ rails g ember_konacha:model_spec gravitation


Sinon notice

The install generator will attempt to download sinon.js, first via httparty and then try via curl. On any exception it will fall back to just copying sinon-1.6.0.js.
