Building the User Interface
We can add a debugging hook to show us what’s going on in our failing scenario. Create a file features/support/debugging.rb:
| support_code/14/features/support/debugging.rb | |
| | After do |scenario| |
| | save_and_open_page if scenario.failed? |
| | end |
The method save_and_open_page is provided by Capybara, but it relies on the launchy gem that isn’t installed automatically. We’ll add it to our Gemfile:
| support_code/14/Gemfile | |
| | source :rubygems |
| | |
| | gem 'sinatra', '1.3.2' |
| | |
| | group :development do |
| | gem 'rspec', '2.11.0' |
| | gem 'cucumber', '1.2.1' |
| | gem 'capybara', '2.0.0.beta2' |
| | gem 'launchy', '2.1.0' |
| | end |
Now run bundle to install the new gem.
