Rspec错误未初始化的常数

Question

我有一家公司要做的招聘任务，涉及Rspec。 克隆了我必须处理的存储库后，我立即遇到了一些错误。 我实际上是Rspec或测试中的一个新手，我想改进，但是这个错误是我找不到的解决方案。

规格/验证/ title_brackets_validator_spec.rb

require "rails_helper"

describe TitleBracketsValidator do
  subject { Validatable.new(title: title) }

  shared_examples "has valid title" do
    it "should be valid" do
      expect(subject).to be_valid
    end
  end

  context "with curly brackets" do
    let(:title) { "The Fellowship of the Ring {Peter Jackson}" }
    it_behaves_like "has valid title"
  end

[ more not important 'contexts'...]
end

class Validatable
  include ActiveModel::Validations
  validates_with TitleBracketsValidator
  attr_accessor :title

  def initialize(title:)
    @title = title
  end
end

在运行bundle exec rspec出现错误：

An error occurred while loading ./spec/validators/title_brackets_validator_spec.rb.
Failure/Error:
  describe TitleBracketsValidator do
    subject { Validatable.new(title: title) }

    shared_examples "has valid title" do
      it "should be valid" do
        expect(subject).to be_valid
      end
    end

    shared_examples "has invalid title" do

仔细阅读作业-也许您的任务之一就是添加文件并实现TitleBracketsValidator类，使其通过所有提供的测试？

我会在您的资源中搜索该课程。 如果不存在-也许您应该创建一个。 如果在那里-那么就是加载问题。 在您的规格中require它，并通知招聘人员您已修复了可能的错误（可能需要加分）
