「無法自動加載常量」使用rspec而不是rails

app/workers/station/http.rb

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

這是我的規格文件。

spec/workers/station/http_spec.rb

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

現在的問題是使用RSpec的運行規範文件時，我發現了以下錯誤。

rspec spec/workers/station/http_spec.rb

/Users/linus/.rvm/gems/[email protected]/gems/activesupport-4.0.4/lib/active_support/dependencies.rb:464:in `load_missing_constant': Unable to autoload constant Station::HTTP, expected app/workers/station/http.rb to define it (LoadError)

    from /Users/linus/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

奇怪的是，everyting在控制檯工作。

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

爲什麼使用這個RSpec的發生，而不是在鐵軌和我將如何解決？

我使用

軌（4.0.4）
rspec的（2.14.1）

我收到了同樣的錯誤。你有沒有想過如何解決這個問題？ –

由於rspec沒有自動加載app/workers路徑，因爲它不是標準導軌佈局，您可以將autoload行添加到spec_helper或直接在規範中要求該文件！ – jfornoff

@jfornoff請插入您的評論作爲答案。這將有助於其他人員遇到這個問題。謝謝您的幫助！ – avital

的app/workers路徑沒有被rspec的自動加載，因爲它不是標準導軌佈局，您可以將自動加載行添加到spec_helper或直接在規範中要求該文件！

由於jfornoff建議你可以添加一個需要聲明的規範與語句像下面這樣：

require "app/workers/station/http"

但是，如果你使用的是Spring Rails應用程序預加載和上面沒有解決該問題，你也可以檢查是否需要重新啓動Spring。您可以測試，而不使用Spring如下運行規範：

bundle exec rspec spec/workers/station/http_spec.rb

......或者......

spring stop # or bin/spring stop 
rspec spec/workers/station/http_spec.rb
