即使 RSpec 在 Rails 控制台中加载，它也不会加载我的类 [英] RSpec doesn't load my class even though it loads in the Rails console

问题描述

我在 app/models/parser 中有一个名为 data.rb 的类，其中包含内容:

I've got a class inside app/models/parser called data.rb with contents :

class Parser::Data 
  def method1
  end
end

在这一点上没什么特别的.我试图在实现太多之前为它编写一个测试，只是为 Rails 安装了默认的 RSpec.

Nothing fancy at this point. I'm trying to write a test for it before implementing too much, just did default RSpec install for Rails.

我的 RSpec 文件在 spec/models/parser/data_spec.rb 中，到目前为止是非常基本的:

My RSpec file is in spec/models/parser/data_spec.rb and is very basic so far:

require 'spec_helper.rb'

describe Parser::Data do
  let(:parser) { Parser::Data.new }
end

当我运行测试时出现此错误:

When I run the test I get this error:

spec/models/parser/data_spec.rb:3:in `<top (required)>': uninitialized constant Parser (NameError)

我尝试将 module Parser 放在同一目录 app/models/parser 中的 Data 类周围，我也尝试移动它到 lib/parser 做相同的模块包装类，并将 lib/parser 添加到 application.rb 中自动加载，但到目前为止没有任何效果.

I tried placing module Parser around the Data class in the same directory app/models/parser, also I've tried moving it to lib/parser doing the same module wrapping class, and added lib/parser to autoload in the application.rb but nothing has worked so far.

我做错了什么?

推荐答案

require 'rails_helper' 而不是 spec_helper.只需要 spec_helper 为我重现了这个问题，并且需要 rails_helper 修复它.在此处详细了解 spec_helper 与 rails_helper(包括性能影响):spec/rails_helper.rb 与 spec/spec_helper.rb 有何不同?我需要吗?

require 'rails_helper' instead of spec_helper. Requiring only spec_helper reproduces the issue for me, and requiring rails_helper fixes it. More on spec_helper vs. rails_helper (including performance implications) here: How is spec/rails_helper.rb different from spec/spec_helper.rb? Do I need it?

我通过使用 bundle exec rspec 运行 RSpec 重现了这个问题.如果我使用 bin/rspec(这是由 spring-commands-rspec gem 生成的 binstub)运行 RSpec，它并不关心我需要哪个帮助文件.我猜弹簧会更急切地加载.

I reproduced the problem by running RSpec with bundle exec rspec. If I run RSpec with bin/rspec (that's a binstub generated by the spring-commands-rspec gem) it doesn't care which helper file I require. I guess spring loads more eagerly.
