Using Jasmine with the asset pipeline
Jasmine does not currently support the asset pipeline, but there's a lovely gem called jasmine-rails that will give us this support. Used in conjunction with jasmine-headless-webkit, you can run your specs in Terminal, similar to
rspec rather than in the browser (and it's fast!).
Add to your Gemfile
First, lets add the necessary dependencies.
group :development, :test do gem 'jasmine-rails' gem 'jasmine-headless-webkit' end
Then remove the extra files it generates.
Because we're using the asset pipeline, we need to tell jasmine where our assets are.
Make a sanity test
At this point, jasmine should be working. Lets make a sanity test to check. Create a file in
describe "Sanity Check", -> it "demonstrates a successful test", -> expect(1).toEqual 1
jasmine-headless-webkit -c (that
-c is for color).
Running Jasmine specs... . PASS: 1 test, 0 failures, 0.007 secs.
A note on OSX Lion
If you're using Lion, you'll likely get a message like...
Can't load, the file may be broken.
...in which case you'll want to load the gem directly from Github.
gem 'jasmine-headless-webkit', :git => https://github.com/johnbintz/jasmine-headless-webkit.git
In some cases you may even need to install from source. Don't worry, it's not hard!
git clone https://github.com/johnbintz/jasmine-headless-webkit.git cd jasmine-headless-webkit gem build jasmine-headless-webkit.gemspec gem install jasmine-headless-webkit.gem
