A set of Ruby gems providing strategies for cleaning databases, primarily to ensure a clean state during tests. It supports multiple ORMs and databases through adapter gems such as database_cleaner-active_record, database_cleaner-mongo, and database_cleaner-redis.

Use cases

• reset database state between tests in a ruby app
• clean database tables after each rspec example
• truncate tables in a test database
• wipe redis and mongo data between test runs
• ensure a clean database state for integration tests

When to choose

• you are writing Ruby tests that touch a database and need repeatable clean state
• you use multiple ORMs (ActiveRecord, Mongoid, Redis) and want a unified cleaning API
• you need configurable strategies like truncation or transactions

When to avoid

• your app is not written in Ruby
• you only need simple transactional test fixtures already provided by your test framework
• you need production data cleanup rather than test-state management
