I\'m building a Rails 3 app using Devise, with Capybara for UI testing. The following test is failing:
class AuthenticationTest < ActionController::Integ
I had the same issue with a setup fairly similar to yours. In my case, switching to ActiveRecord sessions in the initializer solved the problem.
Additionally, make sure you call @user.skip_confirmation! if you are using the "confirmable" module in devise.
