DbSetup is a free, open-source Java API that helps you setup your database data to execute DAO/Repository unit tests. It plays in the same league as tools like DBUnit, but is much simpler, and focuses on a single task: populate the database with test data.
DbSetup is full Java. No XML or YAML file to create. No SQL script. The test data is one control-click away from the source of your test.
DbSetup is simple, and self-contained. You don't need any additional dependency to use it. No log4j, no commons-lang, nothing.
The fastest setup is a setup that you can avoid completely. DbSetup can populate your database only if it needs to, making your read-only tests much faster.
