authlogic flash[:notice]不会出现在webrat步骤中

 Scenario: log in
Given a registered user: "test@test.com" with password: "p@ssword" exists
And I am on the homepage
When I follow "Log in"
And I fill in "Username" with "test@test.com"
And I fill in "Password" with "p@ssword"
And I open the page
And I press "Login"
And I open the page
Then I should see "Login successful!"
And I should see "Logout"

这是我的场景,当我击中

Then I should see "Login successful!"

 def create
@user_session = UserSession.new(params[:user_session])
  if @user_session.save
    flash[:notice] = "Login successful!"
   redirect_to root_url
  else
    render :action => 'new'
  end

结束

是的,我看到了 http://github.com/binarylogic/authlogic/issuesearch?state=open&q=cucumber+flash#issue/142 而这也无济于事

Rails/Cucumber/Webrat: redirect_to, flash[:notice] not working
