Exhaust

Exhaust makes smoke testing a Ember/Rails stack easy.

Installation

Add this line to your application's Gemfile:

gem 'exhaust'

And then execute:

$ bundle

Or install it yourself as:

$ gem install exhaust

Usage

Exhaust sets an ENV variable. Tell Ember how to use it.

// config/environment.js
if (environment === 'development') {
  // Set the ENV.API_HOST to the environment varibale.
  // I like to set a default but it's all up to you.
  ENV.API_HOST = (process.env.API_HOST || 'http://localhost:3000')
}

If using Ember Data, set the host to whatever adapter

// app/adapters/application.js
import DS from 'ember-data';
import config from '../config/environment';

export default DS.RESTAdapter.extend({
  host: config.API_HOST
});

If using Ember.$ reference wherever needed.

import Ember from 'ember'
import config from '../config/environment';


Ember.$.getJSON(config.API_HOST + "/endpoint")

Create a .exhaust.yml

rails:
  path: "/path/to/rails"
  port: 3001
ember:
  path: "/path/to/ember"
  port: 4201

Start the servers

Exhaust.run!

Stop the servers

Exhaust.shutdown!

Using with Cucumber

When used inside a rails app.

# Add to features/support/env.rb
Exhaust.run!
at_exit { Exhaust.shutdown! }

Capybara.configure do |config|
  config.run_server = false
  # Use whatever driver you want
  config.default_driver = :webkit
  config.app_host = Exhaust.ember_host
end

When seperatly from rails.

Add your rails app Gemfile to your own

eval_gemfile File.join("/path/to/rails/Gemfile")

Do something like this in your features/support/env.rb

ENV['RAILS_ENV'] ||= 'test'
path_to_rails = "/path/to/rails"
require File.expand_path("#{path_to_rails}/config/environment")

require 'capybara/cucumber'
require 'database_cleaner'
require 'database_cleaner/cucumber'

DatabaseCleaner.strategy = :truncation

Exhaust.run!
at_exit { Exhaust.shutdown! }

Capybara.configure do |config|
  # Use whatever driver you want
  config.default_driver = :webkit
  config.app_host = Exhaust.ember_host
end

Using with Rspec

# Add to spec/spec_helper.rb
Exhaust.run!
at_exit { Exhaust.shutdown! }

Capybara.configure do |config|
  config.run_server = false
  config.app_host = Exhaust.ember_host
end

Of if you prefer

# Add to spec/spec_helper.rb
before(:all) { Exhaust.run! }
after(:all) { Exhaust.shutdown! }

Capybara.configure do |config|
  config.run_server = false
  config.app_host = Exhaust.ember_host
end

NOTE:

When using outside of the rails environment you will need to manually require the rails environment.

ENV['RAILS_ENV'] ||= 'test'
path_to_rails = "/your/rails/path"
require File.expand_path("#{path_to_rails}/config/environment")

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
