ruby-on-rails - 为什么即使我从不使用 minitest，也会出现此 minitest 错误？

Question

当我运行我的规范时，我得到这个错误，即使我从来没有在我的代码中的任何地方包含 minitest:

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

这是与 rails 4 master 一起使用的。

这是我的 spec_helper.rb 的顶部:

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

这是堆栈跟踪:

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

最新版本的 Minitest(内置于 Ruby 中)与 RSpec 有一些重大变化。

这里有一个与此问题相关的github问题

https://github.com/rspec/rspec-rails/pull/772

将 minitest gem 添加到 Gemfile 是一种临时解决方法。

另一种选择是指向 rspec-rails 的 github master 版本，因为我相信它已在那里修复。
