NameError：未初始化的常量CreatesPointOfInterest Rspec

Question

我正在閱讀《 Rails 5測試處方》這本書，但在運行其中一個示例時遇到問題。 謝謝你的幫助。

我確實有一個名為point_of_interest.rb的模型app / models / point_of_interest.rb

我收到以下錯誤：

 NameError: uninitialized constant CreatesPointOfInterest

規范/工作流程/creates_point_of_interest.rb

class CreatesPointOfInterest
  attr_accessor :name, :point_of_interest

  def initialize(name: "")
   @name = name
  end

  def build
   self.point_of_interest = PointOfInterest.new(name: name)
  end
end

規范/工作流程/creates_point_of_interest_spec.rb

 require "rails_helper"
RSpec.describe CreatesPointOfInterest do
 describe "initialization" do
   it "creates a point of interest given a name" do
     creator = CreatesPointOfInterest.new(name: "Pyramids of Giza")
     creator.build
     expect(creator.point_of_interest.name).to eq("Pyramids of Giza")
   end
 end
end

終端輸出：

〜/桌面/冒險/冒險[開發|！SP] $ rspec

An error occurred while loading 
./spec/workflows/creates_point_of_interest_spec.rb.
Failure/Error:

            creator.build
            expect(creator.point_of_interest.name).to eq("Pyramids of 
           Giza")
         end
   end

Answer 1

您的應用使用的類應位於app/目錄中，而不是spec

因此，您應該具有：

app/workflows/creates_point_of_interest.rb

不

spec/workflows/creates_point_of_interest.rb

您的規范文件名應與類名匹配。 您確定這是正確的嗎？

spec/workflows/create_point_of_interest_spec.rb

但這應該是

spec/workflows/creates_point_of_interest_spec.rb
