使用rspec而不是Rails的“无法自动加载常量”

Question

我有这个文件要测试。

app/workers/station/http.rb

module Worker
  module Station
    class HTTP
      # ...
    end
  end
end

这是我的规格文件。

spec/workers/station/http_spec.rb

describe Worker::Station::HTTP do
  it "should do something"  do
  end 
end

现在的问题是，使用rspec运行spec文件时出现以下错误。

rspec spec/workers/station/http_spec.rb

奇怪的是，一切都可以在控制台中工作。

$ rails c [1] pry(main)> Worker::Station::HTTP => Worker::Station::HTTP

为什么使用rspec而不是在Rails中发生这种情况，我将如何解决？

我正在使用

• 导轨（4.0.4）
• rspec（2.14.1）

该app/workers路径不会被 rspec 自动加载，因为它不是标准的 Rails 布局，您可以将自动加载行添加到您的 spec_helper 或直接在规范中需要文件！
