DatabaseRewinder

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 you have number of tables in your database, the more benefit you will get.

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_all in before(:suite), and clean in after(:each).

RSpec.configure do |config|
  config.before :suite do
    DatabaseRewinder.clean_all
  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 cofiguration.

DatabaseCleaner = DatabaseRewinder
