# DatabaseRewinder [](http://travis-ci.org/amatsuda/database\_rewinder) database\_rewinder is a minimalist's tiny and ultra-fast database cleaner. ## Features * Cleans up tables via DELETE SQL. No other strategies are implemented ATM * Supports multiple databases * Runs extremely fast :dash: ## Why is it fast? database\_rewinder memorizes every table name into which `INSERT` SQL was performed during each test case. Then it executes `DELETE` SQL only against these tables when cleaning. So, the more number of tables you have in your database, the more benefit you will get. ### Credit This strategy was originally devised and implemented by Shingo Morita (@eudoxa) at COOKPAD Inc. ## Supported versions * ActiveRecord 3.2, 4.0, 4.1 * Ruby 2.0, 2.1 ## Installation Add this line to your Gemfile's `:test` group: gem 'database_rewinder' And then execute: $ bundle ## Usage Do `clean` in `after(:each)`. And do `clean_all` or `clean_with` in `before(:suite)` if you'd like to. ```ruby RSpec.configure do |config| config.before :suite do DatabaseRewinder.clean_all # or # DatabaseRewinder.clean_with :any_arg_that_would_be_actually_ignored_anyway end config.after :each do DatabaseRewinder.clean end end ``` ### Pro Tip database\_rewinder is designed to be almost compatible with database\_cleaner. So the following code will probably let your existing app work under database\_rewinder without making any change on your configuration. ```ruby DatabaseCleaner = DatabaseRewinder ``` ## Contributing Send me your pull requests.
