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
