ruby - rspec - 如何与哈希进行比较?语法错误,意外 =>

ruby - rspec - how to compare to a hash? Syntax error, unexpected =>

我的哈希似乎没问题,为什么我会收到语法错误?

得到

SyntaxError:
  .../x_and_o_spec.rb:14: syntax error, unexpected =>, expecting '}'
      expect(board).to eq {0 =>"-", 1 =>"-",  2 =>"-",  3 =>"
                               ^
  .../x_and_o_spec.rb:14: syntax error, unexpected ',', expecting keyword_end
   expect(board).to eq {0 =>"-", 1 =>"-",  2 =>"-",  3 =>"-", 
                                ^
  .../x_and_o_spec.rb:14: syntax error, unexpected ',', expecting end-of-input
  oard).to eq {0 =>"-", 1 =>"-",  2 =>"-",  3 =>"-",  4 =>"-",

如果我注释掉我的期望并打印我得到的哈希值:

{0=>"-", 1=>"-", 2=>"-", 3=>"-", 4=>"-", 5=>"-", 6=>"-", 7=>"-", 8=>"-", 9=>"-"}

那么为什么我的 expect 会给出这些错误消息?

代码

class Grid
  attr_accessor :board
  def initialize
    @board = {}
    (0..9).each do |key|
      @board[key] = "-" 
    end 
  end 
end

测试

it 'Grid has 9 elements, each element is a value of nil, o or X' do
  board = Grid.new.board
  expect(board).to eq {0 =>"-", 1 =>"-",  2 =>"-",  3 =>"-",  4 =>"-",  5 =>"-",  6 =>"-",  7 =>"-",  8 =>"-",  9 =>"-"}
end 

程序员(我)对解析器规则的无知,如果期望是一个散列。
并没有意识到使用 {}'s

的散列/块问题

用括号解决它!

 expect(board).to eq    ({0 =>"-", 1 =>"-",  ...  9 =>"-"})
 # added these parens: /\                                /\
