我有一个类和一个这样的方法......

class Player

  attr_reader :boardpiece # i exist so game can read me

  def initialize(letter)
    @boardpiece = letter
  end

  def move_human(game, board)
    @game_two = game

    puts "human move..."

    human_move = gets.chomp

    human_symbol = human_move.to_sym

    # look for move as key in board.grid
    if board.grid.has_key?(human_symbol)
      if board.grid[human_symbol] == " "
        #puts "bingo"  
        @move = human_symbol            
      else
        puts "spot taken...try again"
        move_human(@game_two, board)
      end
    else
      puts "invalid move...try again"
      move_human(@game_two, board)
    end 

  end
end

我正在尝试在 RSpec 中为它编写一个测试...

require 'game'
require 'board'

describe Player do
  describe 'move_human' do
    it 'receives cli input' do
      player_h = Player.new('X')
      player_c = Player.new('O')
      board = Board.new
      game = Game.new(player_h, player_c, board)          

      player_h.move_human('X', board).should_receive(:puts).with('human move...')

      game.play
    end
    xit 'and returns a move value'

  end
end

我收到此错误作为输出....我做错了什么？

@thefonso，不完全是。您想要存根发生在播放器对象上的“获取”调用，而不是 move_human 方法调用的结果。

所以，你会说 player_h.stub(:gets).and_return("some input from the user")。同样的事情也适用于你的 should_receive(:puts) 位。在调用这些方法的地方发生方法调用之前，您需要设置这些期望。因此，您的规范可能具有以下内容：

# These setup expectations for when "gets" and "puts" are called later...
player_h.stub(:gets).and_return("some input from the user")
player_h.should_receive(:puts).with("human move...")

# And then we run the method where those expectations above will get triggered:
player_h.move_human('X', board)

希望有帮助。

您可以为您的课程存根该方法。

player_h.stub(:gets).and_return("Some string")
