Question

Ok, rspec noob here…I’ve got a simple method and I want to test. I just want the test to say…when this method is called it returns a symbol…any pointers?

the method….

  def defend_corners(board)
    @board = board
    @corners = {
        :a1=>" ", :a3=>" ",
        :c1=>" ", :c3=>" "
    }
    available_moves = @corners.select{ |k, v| v == " " }.keys
    puts "random move - corners"
    @move = available_moves[rand(available_moves.length)]
    return @move
  end

current test….

  describe 'defend_corners' do
    it 'returns corner move' do
      myboard = Board.new

      @player_computer.defend_corners(myboard).should #return a symbol???
    end  
  end

Answer 1

@player_computer.defend_corners(myboard).should be_an_instance_of(Symbol)

or

@player_computer.defend_corners(myboard).should be_a_kind_of(Symbol)

or

@player_computer.defend_corners(myboard).should be_a(Symbol)
