Given /^I have one\s+user "([^\"]*)" with email "([^\"]*)" and password "([^\"]*)"$/ do |username,email,password|
  @user = User.new(:email => email,:username=>username,:password => password,:password_confirmation => password)

Given /^I am an authenticated user$/ do

  And %{I go to the user login page}
  And %{I fill in "user_username" with "#{name}"}
  And %{I fill in "user_password" with "#{password}"}
  And %{I press "Sign in"}
end
