Authlogic: connexion deux fois sur le même test

Question

Est-il possible de se déconnecter et de se connecter à un autre utilisateur lors d'un test avec Authlogic?

Le cas de test suivant ne vient

class MessagesControllerTest < ActionController::TestCase 
    setup :activate_authlogic 

    should "sender send a message and recipient delete it" do 
    @sender = Factory(:user, :login => 'sender') 
    @recipient = Factory(:user, :login => 'recipient') 

    UserSession.create(@sender) 
    post :create, :user_id => @recipient.id, :message => Factory.attributes_for(:message) 
    assert_equal @sender, assigns(:current_user) 

    UserSession.create(@recipient) 
    post :destroy, :user_id => @recipient.id, :message => @message 
    assert_equal @recipient, assigns(:current_user) 
    end 
end 

Ce qui est fou est que params session de demande ... ok regarder

# UserSession.create(@sender) 
"user_credentials"=> "605a73e0f1b4dcecf5495d549b9d33eb6d3197f3a1fdb033c86bca456a0a0c75a42b63c924edb5d071f6d748aea3870f312a908eb501e6814c69abdab9bbf387", 
"user_credentials_id"=>1 


# UserSession.create(@recipient) 
"user_credentials"=> "e14363b2065b7202e766205e807d6b531e230a136c70ea13c0853c7c0f275fb95f0185b9f17a934483cadda693e50956d1bfda8c820895f574a06861479af18c", 
"flash"=>{:notice=>"Message was successfully created."}, 
"user_credentials_id"=>2
