Error with page.driver.debug

[gmile]

I have an issue using page.driver.debug in my tests.

I double-checked if I am providing an inspector: true key-value pair to the test. Here's what it looks like (though not sure how this might help):

scenario 'User removes product from favorites', js: true, inspector: true do
  favorite = Factory :favorite, user: user

  visit("/products/#{favorite.variant.permalink}/")

  click_link 'Remove from favorites'

  page.should     have_content('Add to favorites')
  page.should_not have_content('Remove from favorites')
end

And here's an error:

Failure/Error: page.driver.debug
     NoMethodError:
       private method `open' called for nil:NilClass
     # /home/gmile/.rvm/gems/ruby-1.9.3-p125@christ/gems/poltergeist-0.6.0/lib/capybara/poltergeist/driver.rb:107:in `debug'
     # ... the rest of stack trace is related to rspec and app specific files ...

I will be providing any additional info if needed.

P.S. just in case this might be a relevant info: I am using Ubuntu 11.10 and phantomjs 1.5

You need to setup Poltergeist with inspector: true, not provide it as metadata to your RSpec test. Example:

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, inspector: true)
end

However, probably we should raise an error if someone calls page.driver.debug if the driver wasn't started with inspector: true, so I'll leave this open to track that.
