Cleaning test databases faster

We have been using database_cleaner for years and recently found out about database_rewinder which is a bit faster with projects that have a lot of tables. Unfortunately it didn't support Mongoid, ActiveRecord transactions and used monkey patches for ActiveRecord classes, so we decided to create a new gem.

ebeigarts/database_flusher

Main Features

• No monkey patching — uses ActiveSupport::Notifications and Mongo::Monitoring::Global to catch INSERTstatements
• Fast :deletion strategy that cleans only tables/collections where INSERT statements were performed
• Faster disable_referential_integrity for PostgreSQL
• Executes multiple DELETE statements as one query with ActiveRecord
• Supports only one database for each ORM
