Hello everybody,

I had a following problem today. My test that I used to run successfully
with "ruby -Itest" is failing when it is run with "rake
test:integration".
I can't understand why.

Could you please check below the test class definition and output that
"ruby -Itest" and "rake test:integration" give me.

Thank you in advance,
Evgeny

class ActorChatSpacesTest < ActionController::IntegrationTest
  fixtures :actors, :spaces, :invitations, :roles

  def test_actor_chats
    actor = actors(:Christophe)
    chats = []
    chat_spaces = Space.get_chat_spaces()
    chat_spaces.each do |chat_space|
      if chat_space.actors.include?(actor)
        chats = chats << chat_space
      end
    end
    assert actor.chats.eql?(chats)
  end
end
