Question

我有一个班级和方法......

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

我将此错误视为输出....我做错了什么？

Board

Answer 1

@thefonso，不太完整。你想要存在播放器对象上发生的“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（“来自用户的一些输入”）。同样的事情也适用于你的should_receive（：puts）位。在调用这些方法的方法调用之前，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)

希望有所帮助。

Answer 2

你可以为你的班级存出方法。

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

这个RSpec错误告诉我什么？
