Jasmine Phantom provides a rake task that runs your jasmine specs via phantomjs. It requires jasmine >= 1.2.0.
Add jasmine 1.2.0 and jasmine-phantom to your gemfile:
gem 'jasmine', '1.2.0'
gem 'jasmine-phantom'
and run bundle install.
Then run bundle exec rake jasmine and check http://localhost:8888/ to make sure your jasmine specs are passing.
This gem uses https://github.com/colszowka/phantomjs-gem to automatically download an appropriate PhantomJS instance to the machine.
Finally, run bundle exec rake jasmine:phantom:ci and you should see output similar to:
