Je n'understang pas ce qui est faux.

Answer 1

Si vous ne souhaitez pas utiliser Webrat, vous pouvez utiliser

response.body.should include 'Contact</h1>' 

Plutôt que

response.should have_selector("title", :content => "Contact") 

Ce qui est un peu moins propre, je suis d'accord.

Answer 2

Rééditer votre Gemfile et tapez

gem 'webrat' 

puis

Type

bundle install
