我正在运行这部分测试:

 describe Dictionary do
   before do
     @d = Dictionary.new
   end

    it 'can check whether a given keyword exists' do
        @d.include?('fish').should be_false
      end

使用此代码:

class Dictionary
  def initialize
    @hash = {}
  end 

  def add(new_entry)
    new_entry.class == String ? @hash[new_entry] = nil : new_entry.each { |noun, definition| @hash[noun] = definition}    
  end 

  def entries
    @hash 
  end 

  def keywords
    @hash.keys
  end

  def include?(word)
    if @hash.has_key?(word)
      true
    else 
      false
    end 
  end 
end 

我不知道我做错了什么,但我的测试仍然失败并说:

> 1) Dictionary can check whether a given keyword exists
>      Failure/Error: …
