Utilizing Jasmine and taking full advantage of the Rails 3.1 asset pipeline. Jasminerice removes any excuse YOU have for not testing your out of control sprawl of CoffeeScript files. This project rocks and uses the MIT-LICENSE.
See guard-jasmine for details.
This is a gem specifically for Rails 3.1. Just include it in
your Gemfile
:
group :development, :test do
gem "jasminerice"
end
The engine is automatically mounted into your application in the development
and test environments. If you'd like to change that behavior, you can
override the array Jasminerice.environments
in an initializer.
Create a file spec/javascripts/spec.js.coffee
with the following content:
#=require_tree ./
This pulls in all your specs from the javascripts
directory into Jasmine:
spec/javascripts/*_spec.js.coffee
spec/javascripts/*_spec.js
spec/javascripts/*_spec.js.erb
The Rails 3.1 asset pipeline using Sprockets and Tilt ensure conversion.
As well you can use the #require
dependency mechanisms in your specs to
pull dependencies. Here's an example spec/javascripts/foo_spec.js.coffee
:
#= require foo
#= require bar
describe "Foo", ->
it "it is not bar", ->
v = new Foo()
expect(v.bar()).toEqual(false)
describe "Bar", ->
it "it is not foo", ->
v = new Bar()
expect(v.foo()).toEqual(false)
For including stylesheets in your specs, Jasminerice uses spec/javascripts/spec.css
.
Use Sprockets directives to include the right css files:
/*
*= require application
*/
Jasminerice makes files located in the spec/javascripts/fixtures
directory available
as fixture. For example, a file spec/javascripts/fixtures/baz.html.haml
with the
following content:
%h2 Test Fixture
%p Using fixtures
is made available under the URL /jasmine/fixtures/baz
. Since Jasminerice automatically
makes a patched version of jasmine-jquery
available in your specs, you can load the baz
fixture in your spec with:
loadFixtures 'baz'
You can declare Jasminerice::HelperMethods (perhaps put inside lib/) to make helpers available to jasminerice fixtures.
Now start your server
rails s
Goto
http://localhost:3000/jasmine
and there are your specs.
If you use Require.js in your project and need to load your
modules in your jasmine specs, there is an option to prevent jasminerice from automatically
executing the test runner before the modules are defined. This enables you to start the
execution manually whenever you want in your spec/javascripts/spec.js.coffee
file:
#= require your/specs/and/other/stuff
# at the end of this file add:
jasmine.rice.autoExecute = false
define 'jasmine.waitsfor.requirejs', ->
require ['jasmine.waitsfor.requirejs'], ->
jasmine.getEnv().execute()
The shown example defines a dummy module in require.js that is required immediately on the next line. This is a simple hack to wait until require.js has initialized all modules and start the jasmine runner after that.
Of course you can use jasmine.rice.autoExecute = false
also for all other cases where you need
to control when your specs should be executed!
