#rspec test code
@room = FactoryGirl.build(:room)

#factory definition
factory :room do
  length {10}
  width {20}
end

#code implementation
class Room
  attr_accessor :length, :width

  def initialize(length,width)
     @length = length
     @width = width 
  end

end

尝试构建@room时,运行rspec会导致此错误

ArgumentError:参数数量错误(0表示2)
