【问题描述】:
更新:这根本不是关于我的数据库,而是关于 Spree 存储在被我的测试污染的内存缓存中的首选项。请参阅下面的答案。
我在 Rails 3.1.4 上运行 Spree 应用程序,使用 Ruby 1.9.3-p0、rspec-rails 2.8.1、rspec 2.8.0。
Rspec 在我的开发机器上与 Webrick 进行了奇怪的交互,这让我认为它正在以某种方式使正在运行的 Webrick 实例切换到使用测试数据库。
我的 HomeController 有一个规格:
require 'spec_helper'
describe HomeController do
render_views
describe "GET 'index'" do
it "should be successful" do
get 'index'
response.should be_success
end
end
end
当我在本地主机(开发机器)上启动 Webrick 时,我的主页在浏览器中运行良好。我第一次在我的 HomeController 上运行 Rspec,它的索引操作对应于主页,我的测试通过了。
Rspec 运行后,Webrick 中的页面中断,因为以前填充文本数据的数据库字段现在为零。随后的 Rspec 迭代也会中断。
那么,Rspec 是否让 Webrick 停止使用我的开发数据库并开始使用我的测试数据库,为什么?是 spec_helper.rb 中的ENV["RAILS_ENV"] ||= 'test' 行吗?
(这是我的 spec_helper.rb 和清理过的 database.yml:)
spec_helper.rb(我安装了 Spork 和 Autotest,但是当我不运行它们时也会出现此错误。)
require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'
Spork.prefork do
# Loading more in this block will cause your tests to run faster. However,
# if you change any configuration or code from libraries loaded here, you'll
# need to restart spork for it take effect.
# This file is copied to ~/spec when you run 'ruby script/generate rspec'
# from the project root directory.
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)

#config.include Devise::TestHelpers, :type => :controller

match do |model|

end
end
end

【问题讨论】:
-
我应该补充一点,在我重新启动 Webrick 后,整个过程又开始了。 Webrick 找到丢失的数据库字段(大概仍在开发数据库中)。 Rspec 也会进行一次迭代。
-
我只是使用了 Unicorn 而不是 WEbrick,它重现了同样的错误(尽管我必须运行两次 Rspec 才能出现)。
-
在 Ruby 1.9.2 上也是一个问题。如果我注释掉
ENV["RAILS_ENV"] ||= 'test',那么 Rspec 会继续通过,问题就会消失——但这不是正确的答案!如果我做到ENV["RAILS_ENV"] = 'test',问题仍然存在。
