Rspec錯誤：未讀取我在數組中的擴展方法

Question

我不斷收到Undefined method all_empty?錯誤。我是否錯誤地開課？

core_extensions.rb

class Array 
    def all_empty? 
     self.all? { |element| element.to_s.empty? } 
    end 
end 

core_extensions_spec.rb：

require "spec_helper" 

describe Array do 
    context "#all_empty?" do 
     it "returns true if all elements of the Array are empty" do 
      expect(["","",""].all_empty?).to be true 
     end 

     it "returns false if some of the Array elements are not empty" do 
      expect(["","1", Object.new, :a].all_empty?).to be false 
     end 

     it "returns true for an empty Array" do 
      expect([].all_empty?).to be true 
     end 
    end 
end

只是在你的core_extensions_spec.rb添加require_relative 'path/to/core_extensions.rb'。

如果您在其他測試中需要core_extensions.rb，您可以將此行添加到您的spec_helper.rb。
