Passes the test with a wrong behaviour

[abdellani]

Hello
I don't understand why my program passes this test ?
Instead of "a---a-", my method returns "------" as I checked with byebug. Also, my post /guess is still empty!

  post '/guess' do
    letter = params[:guess].to_s[0]
    ### YOUR CODE HERE ###
    flash[:message]="You have already used that letter." if not @game.word.include?(letter)
    redirect '/show'
  end

    Given I start a new game with word "animal"             # features/step_definitions/game_steps.rb:12

[47, 56] in /home/user/edx/agile_dev_basics/hw-sinatra-saas-hangperson/lib/hangperson_game.rb
 # def word_with_guesses
   47: 	dashed_word=@word.clone
   48: 	dashed_word.each_char do |l|
   49: 		dashed_word.gsub! l,"-" if not guesses.include?(l)
   50: 	end
   51:         byebug
=> 52: 	dashed_word
   53:   end
   54: 
   55:   def check_win_or_lose
   56: 	return :win if not word_with_guesses.include? ("-")
(byebug) "------"
(byebug)     When I guess "a"                                        # features/step_definitions/game_steps.rb:19
    Then I should see "a---a-" within "span.word"           # features/step_definitions/game_steps.rb:71

Kind regards.
