Question

好的，所以我是一个rspec noob，我正在尝试测试一个位于模块内部的方法。下面是我的测试文件，我正在测试的代码，以及我得到的错误。任何指导都将不胜感激。

提前致谢。

这是我的spec文件gamestat_spec.rb

require 'gamestate'
require 'board'


describe 'Gamestate module' do
  before (:each) do
    @player_human = Player.get_player('X')
    @player_computer = Player.get_player('O')    
  end
  describe 'is_a_human_win' do
    it 'receives current board' do
      class GamestateTester
        include ::GameState
      end
      human_win_test = GamestateTester.new
      myboard = Board.new
      myboard.grid[:a1] = "X"
      myboard.grid[:b2] = "X"
      myboard.grid[:c3] = "X"
      human_win_tester.is_a_human_win(@myboard).should_receive(:puts)
    end
    xit 'looks for human win'
    xit 'if win found returns...Human Wins'
  end
  describe 'is_a_computer_win' do
    xit 'receives current board'
    xit 'looks for computer win'
    xit 'if win found returns...Computer Wins'
  end
end

这是我正在测试的模块文件... gamestate.rb ....

module GameState

  def is_a_human_win(board)

  win_moves = {
    :wm01 => {:a1=>"X", :a2=>" ", :a3=>" ", :b1=>" ", :b2=>"X", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>"X"},
    :wm02 => {:a1=>" ", :a2=>"X", :a3=>" ", :b1=>" ", :b2=>"X", :b3=>" ", :c1=>" ", :c2=>"X", :c3=>" "},
    :wm03 => {:a1=>" ", :a2=>" ", :a3=>"X", :b1=>" ", :b2=>"X", :b3=>" ", :c1=>"X", :c2=>" ", :c3=>" "},

    :wm05 => {:a1=>"X", :a2=>"X", :a3=>"X", :b1=>" ", :b2=>" ", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "},
    :wm06 => {:a1=>" ", :a2=>" ", :a3=>" ", :b1=>" ", :b2=>" ", :b3=>" ", :c1=>"X", :c2=>"X", :c3=>"X"},
    :wm07 => {:a1=>"X", :a2=>" ", :a3=>" ", :b1=>"X", :b2=>" ", :b3=>" ", :c1=>"X", :c2=>" ", :c3=>" "},
    :wm08 => {:a1=>" ", :a2=>" ", :a3=>"X", :b1=>" ", :b2=>" ", :b3=>"X", :c1=>" ", :c2=>" ", :c3=>"X"}
  }

  x_on_the_gameboard = board.grid.select{ |k, v| v == "X" }.keys


    win_moves.each do |k,v|
      win_moves_keys = v.select{ |k, v| v == "X"}.keys

      matching_moves = win_moves_keys & x_on_the_gameboard

      if matching_moves.length >= 3 

        p 'key: '+k.to_s

        string_contains = k.to_s
        if string_contains =~ /wm/ 
          puts "Human Wins"
          # return 1
          exit
        else

        end
      end
    end
  end

  def is_a_computer_win(board)

  ai_winmoves = {
    :wm01 => {:a1=>"O", :a2=>" ", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>"O"},
    :wm02 => {:a1=>" ", :a2=>"O", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>"O", :c3=>" "},
    :wm03 => {:a1=>" ", :a2=>" ", :a3=>"O", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>"O", :c2=>" ", :c3=>" "},
    :wm04 => {:a1=>" ", :a2=>" ", :a3=>" ", :b1=>"O", :b2=>"O", :b3=>"O", :c1=>" ", :c2=>" ", :c3=>" "},
    :wm05 => {:a1=>"O", :a2=>"O", :a3=>"O", :b1=>" ", :b2=>" ", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "},
    :wm06 => {:a1=>" ", :a2=>" ", :a3=>" ", :b1=>" ", :b2=>" ", :b3=>" ", :c1=>"O", :c2=>"O", :c3=>"O"},
    :wm07 => {:a1=>"O", :a2=>" ", :a3=>" ", :b1=>"O", :b2=>" ", :b3=>" ", :c1=>"O", :c2=>" ", :c3=>" "},
    :wm08 => {:a1=>" ", :a2=>" ", :a3=>"O", :b1=>" ", :b2=>" ", :b3=>"O", :c1=>" ", :c2=>" ", :c3=>"O"}
  }

  o_on_the_gameboard = board.grid.select{ |k, v| v == "O" }.keys


    ai_winmoves.each do |k,v|
      ai_winmoves_keys = v.select{ |k, v| v == "O"}.keys

      matching_moves = ai_winmoves_keys & o_on_the_gameboard

      if matching_moves.length >= 3 

        p 'key: '+k.to_s

        test_string_contains = k.to_s
        if test_string_contains =~ /wm/ 
          puts "Computer Wins"
          # return -1
          exit
        else

        end
      end
    end
  end
end

这是我得到的错误......

Answer 1

看起来它甚至不是Rspec问题，只是ruby语法。：）

这部分：

 class GamestateTester
   include 'gamestate'
 end

应该是：

 class GamestateTester
   include ::GameState
 end

Answer 2

简单的旧错字。你的对象中有一个额外的呃;）

human_win_test = GamestateTester.new
...
human_win_tester.should ....
