当我在命令提示符下键入时

ruby bowling_spec.rb

我收到以下错误

测试

# bowling_spec.rb
require 'bowling'

describe Bowling,"#score" do
  it "returns 0 for all gutter game" do
    bowling = Bowling.new
    20.times { bowling.hit(0) }
    bowling.score.should == 0
  end
end

码

# bowling.rb
class Bowling
  def hit(pins)
  end

  def score
    0
  end
end
