Question

我写了黄瓜测试用例，现在我需要回滚数据库而不是现有数据库。我使用了seyium web-driver和capybara 2.0.2。当我尝试过：

DatabaseCleaner[:active_record].strategy = :truncation

删除了我mysql表的所有记录。之后我改变了这个是：

 DatabaseCleaner[:active_record].strategy = :transaction

但这不是滚动数据库。

我的database.rb是：

require 'active_record'
require 'database_cleaner'
require 'database_cleaner/cucumber'

ActiveRecord::Base.establish_connection(
    :adapter => 'mysql2',
    :database => 'aq_test',
    :username => 'root',
    :password => 'manager'  )

class ActiveRecord::Base
    mattr_accessor :shared_connection
    @@shared_connection = nil

    def self.connection
        @@shared_connection || retrieve_connection
    end
end
ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection
DatabaseCleaner[:active_record].strategy = :transaction

但这也不会回滚数据库注意：我只想回滚由测试用例运行的最后一个事务

抱歉我的英文

database_cleaner github页面说明将该代码放入features/support/database_cleaner.rb文件中：

begin
  require 'database_cleaner'
  require 'database_cleaner/cucumber'

  DatabaseCleaner.strategy = :truncation
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end

Before do
  DatabaseCleaner.start
end

After do |scenario|
  DatabaseCleaner.clean
end

如何使用DatabaseCleaner [：active_record] .strategy =：与selenium的事务
