This gems makes it possible to use Capybara for (partially) remote testing. It inherits most functionality from the RackTest driver and only uses Mechanize for remote requests.

It is currently in use to test the integration between a Rails application and Twitter authorization and sharing.

This gem is a Capybara extension. I have been inspired by the Capybara driver and some earlier efforts for a Mechanize driver.

Thanks to Pinkelstar for giving me the time and the need to develop this gem.


gem install capybara-mechanize

Usage without Cucumber

require 'capybara/mechanize'

Usage with Cucumber and tags

A @mechanize tag is added to your hooks when you add the following line to your env.rb

require 'capybara/mechanize/cucumber'

The following scenario will then be using the Mechanize driver

Scenario: do something remote
  When I click the remote link

Remote testing

When you want to use this driver to test a remote application. You have to set the app_host:

Capybara.app_host = "http://www.yourapp.com"

Note that I haven't tested this case for my self yet. The Capybara tests pass for this situation though so it should work! Please provide me with feedback if it doesn't.

Running tests

Until this library is merged with capybara there needs to be local app and you need to add the following to your host file: capybara-testapp.heroku.com 

Run bundler

bundle install

Run the app with the following line:

bundle exec ruby -rrubygems lib/capybara/spec/extended_test_app.rb

Then you are ready to run the test like so

rake spec


  • Make the last 12 failing remote session spec pass, see remote_mechanize_spec and uncomment one line there to see them fail
  • Test this driver with non-rack/non-ruby projects

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
