Following links in emails with Capybara

Although this just got added to the Capybara README, I thought it worth a quick note here.

When using Rack::Test, beware if attempting to visit absolute URLs. For example, a session might not be shared between visits to posts_path and posts_url. If testing an absolute URL in an Action Mailer email, set default_url_options to match the Rails default of http://www.example.com.

So, for a Rails app, you’d add this to your config/environments/test.rb file:

config.action_mailer.default_url_options = {:host => 'www.example.com'}

Otherwise, you’ll find yourself losing your user session between requests (steps) in your test.
