Question

UPDATE：这根本不是关于我的数据库，而是关于Spree在我的测试污染的内存缓存中存储的首选项。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奇怪地交互，让我觉得它以某种方式使一个正在运行的Webrick实例切换到使用测试数据库。

我的HomeController有一个规范：

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

当我在我的localhost（开发机器）上启动Webrick时，我的主页在浏览器中正常工作。我第一次在我的HomeController上运行Rspec，其索引操作对应于主页，我的测试通过了。

在Rspec运行之后，Webrick中的页面中断，因为之前填充了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？它是spec_helper.rb中的ENV["RAILS_ENV"] ||= 'test'行吗？

（这是我的spec_helper.rb和已清理的database.yml：）

spec_helper.rb（我安装了Spork和Autotest，但是当我没有运行它时会发生此错误。）

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__)
require 'rspec/rails'
# require 'capybara/rspec'

# Requires supporting files with custom matchers and macros, etc,
# in ./support/ and its subdirectories.
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}

#require 'factories'

RSpec.configure do |config|
  # == Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr
  config.mock_with :rspec

  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  #config.include Devise::TestHelpers, :type => :controller
  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, comment the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true
end

@configuration ||= AppConfiguration.find_or_create_by_name("Default configuration")

PAYMENT_STATES = Payment.state_machine.states.keys unless defined? PAYMENT_STATES
SHIPMENT_STATES = Shipment.state_machine.states.keys unless defined? SHIPMENT_STATES
ORDER_STATES = Order.state_machine.states.keys unless defined? ORDER_STATES

# Usage:
#
# context "factory" do
#   it { should have_valid_factory(:address) }
# end
RSpec::Matchers.define :have_valid_factory do |factory_name|
  match do |model|
    Factory(factory_name).new_record?.should be_false
  end
end
end

Spork.each_run do
  # This code will be run each time you run your specs.
end

的database.yml

development:
  adapter: mysql2
  host: localhost
  database: <APP>_development 
  username: <USER>
  password: <PASSWORD>

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  host: localhost
  database: <APP>_test 
  username: <USER>
  password: <PASSWORD>

production:
  adapter: mysql2
  host: localhost
  database: <APP>_prod
  username: <PROD_USER>
  password: <PROD_PASSWORD>

事实证明，这是存储在缓存中的首选项的问题，而不是数据库。

Josh Jacobs回答（并解释得非常好）here

解决方案是为测试和开发配置不同的缓存存储。在test.rb中，我添加了config.cache_store =：memory_store，重启了spork，一切正常。

Rspec改变偏好值，污染开发环境
