Rspec错误未初始化常量

Question

我有一个公司的招聘任务要做，涉及Rspec。在克隆了他们的repo(我必须在上面工作(之后，我立即遇到了一些错误。我对Rspec或测试是一个全新的东西，实际上，我想改进，但这个错误是我找不到解决方案的。

规范/验证器/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时，我得到一个错误：

An error occurred while loading ./spec/validators/title_brackets_validator_spec.rb.
Failure/Error:

仔细阅读您的作业-也许您的任务之一是添加文件并实现类TitleBracketsValidator，以便它通过所有提供的测试？

我会在你的资料中查找这门课。如果没有，也许你应该创建一个。如果它在那里，那就是装载问题。require在你的规格中，并通知招聘人员你修复了一个可能的错误(可能是为了获得额外的分数(
