Why isn't jasmine running any of my specs?

I added gem 'jasmine', '~> 2.0.0' in my Gemfile (group :development, :test) and ran the generator rails g jasmine:install.

I have one simple spec:

# spec/javascripts/truth_spec.js 
describe("Truth", function() {
  it("herps the derps", function() {
    expect(true).toEqual(true);
  });
});

When I run rake jasmine I get presumably normal output:

your server is running here: http://localhost:8888/
your tests are here:         /Users/jared/git/givegab/spec/javascripts
your source files are here:  /Users/jared/git/givegab

>> Thin web server (v1.5.1 codename Straight Razor)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:8888, CTRL+C to stop

I open http://localhost:8888/ in my browser and I get a blank grey screen. My JS console is empty, no errors, and when I trace execution using a debugger I can step through boot.js and jasmine.js. No errors are raised.

I can set a debugger breakpoint in truth_spec.js and it never gets hit.

This is my first time using jasmine, so please assume I am missing something obvious.

My colleague has found the root problem. To our great embarrassment, we were overwriting window.onload. I can't think of any way jasmine (or S.O.) could have identified such a foolish mistake. Thanks for taking the time to help us troubleshoot this.

The gem author ragaskar helped us troubleshoot this, and gave us some good tips.

Make sure you have a file in config/initializers/ called jasminerice.rb, with the following contents in it, if you want to use the interactive web version:

# Use this file to set configuration options for Jasminerice, all of these are initialized to their respective defaults,
# but you can change them here.
if defined?(Jasminerice) == 'constant'
  Jasminerice.setup do |config|
    # Tell Jasminerice to automatically mount itself in your application. If set to false, you must manually mount the
    # engine in order to use Jasminerice.
    #config.mount = true

    # If automatically mounting Jasminerice, specify the location that it should be mounted at.  Defaults to /jasmine, so
    # you could access your tests at http://YOUR_SERVER_URL/jasmine
    #config.mount_at = '/jasmine'

    # Specify a path where your fixutures can be found. Defaults to 'spec/javascripts/fixtures'
    #config.fixture_path = 'spec/javascripts/fixtures'
  end
end

Be sure to restart your rails server afterward. This initializer sets up the routes at runtime for the jasmine web view, so if you run rake routes | grep jasmine, you should see the following:

jasminerice /jasmine Jasminerice::Engine GET /spec/:spec_id/fixtures/*filename(.:format) jasminerice/spec#fixtures spec_index GET /spec(.:format) jasminerice/spec#index GET /fixtures/*filename(.:format) jasminerice/spec#fixtures GET /(:suite)(.:format) jasminerice/spec#index

If jasmine is setup correctly, then opening http://localhost:8888/jasmine in your browser should run all of your specs.

You can also run specific specs with:

http://localhost:8888/jasmine?spec=herps the derps
