Question

尝试在Rspec中测试我的循环，但是不确定尝试它的最佳方法。尝试了几种不同的选项，但是当我测试输出问题和答案时，似乎都失败了。输出给了我整个循环运行的结果，而答案给了我平局的回报，而不仅仅是gets.chomp答案。

我正在尝试设计一个Tic Tac Toe游戏，并使用循环方法在班上进行游戏。但是，当涉及到在TDD中进行测试时，它会不断显示错误消息。我的代码如下：


def initialize
   @player1 = []
   @player2 = []
end

 def play
   i = 0
   loop do
     i += 1
     print "Player 1 play: "
     answer = gets.chomp
     @player1.push(answer)
       if WINNING_RESULTS.include?(@player1[0..2].sort)
         return "Player 1 Wins"
         break
       end
     if i == 9
       return "It's a Draw"
     end
     i += 1
     print "Player 2 play: "
     answer1 = gets.chomp
     @player2.push(answer1)
       if WINNING_RESULTS.include?(@player2[0..2].sort)
         return "Player 2 Wins"
         break
       end
   end
 end

我希望结果如下：

it "asks player one to pick a move" do
    allow_any_instance_of(Game).to receive(:gets).and_return("TL")
    expect { subject.play }.to output("Player 1 play: ").to_stdout
  end

上面的那个打印出“ Player 1播放：”“ Player 2：播放”的整个循环，直到我达到9。

it "should receive an answer from the user" do
  allow_any_instance_of(Game).to receive(:gets).and_return("TL")
  expect(subject.play).to eq("TL")
end

上面的内容是：预期的“ TL”实际为“抽奖”

测试循环代码的输出和gets.chomp
