Rspec :js => true issue (Rails 3)

Hey all,   I'm trying to get some Javascript test coverage in my app, so I decided to implement Rspec and Capybara with Selenium. I follow Ryan Bate's Railscast episode 257 to a tee, but I still can't get it to work. Problems arise when I add :js => true. Without it, the following DOES work. Here's the spec:

describe "Info Page" do   describe "GET /premium" do     it "shows the info page", :js => true do       visit '/premium'     end   end end

Which, when executed, outputs the following (with --trace):

Failures:   1) Info Page GET /premium shows the info page      Failure/Error: visit '/premium'      TypeError:        Zip is not a module      # ./spec/requests/info_spec.rb:6:in `block (3 levels) in <top (required)>'

Finished in 13.15 seconds 1 example, 1 failure

Failed examples:

I am having a really hard time trying to track down the cause of this... Heck, the only reason why I am using RSpec and Capybara is for Javascript support (other tests in the app use test unit).

Any and all help is appreciated!

UPDATE:

I got this working by using tips from the following blog: http://www.neotericdesign.com/blog/capybara-webkit-rspec-and-javascript

I changed my gemfile to use the following gems:

  # For Testing w/ Javascript support.   # Rspec needs to be in the development group to expose generators and rake tasks without   # having to type RAILS_ENV=test.   gem 'rspec-rails', '~> 2.7.0', group: :development   gem 'capybara-webkit', '~> 0.7.2'

  # Debugging Tests   gem 'launchy'

  # This allows for database transactions to refresh during testing with   # capybara and selenium.   gem 'database_cleaner', '~> 0.6.7'

As a dependency of capybara-webkit, I also installed the QT libraries.

I still don't know why I was getting the "Zip is not a module" error, but I hope this helps someone in the future.

Okay, maybe I spoke too soon. Can't help but be hopeful, lol.

I have a bunch of "fill_in" statements for the page I'm testing, such as:

fill_in "shopper_first_name", with: 'Jeffrey'

etc... however, although I'm not getting an error anymore, it DOES NOT fill in the text UNLESS I get rid of :js => true. I'm going to be testing ajax, so I need this functionality...

This headache is turning into a migraine...

Advice?

Thanks,   - Jeff

*headslam* I just needed to RTFM more closely. I assumed the fields weren't being populated because I was using launchy to save_and_open_page to see if it had done so. Capybara-webkit doesn't instantiate a browser though, it access the renderer (webkit) directly.

This is working now :stuck_out_tongue:
