Writing unit and component tests for objects with external dependencies, such as databases or other objects, can prove arduous, as those dependencies may hinder isolation. Ultimately, effective white-box tests isolate an object by controlling outside dependencies, so as to manipulate its state or associated behavior.
The DbUnit framework's ability to manage the state of a database throughout a test's lifecycle enables rapid test-case creation and adoption; furthermore, by controlling a major dependency, tests that utilize the DbUnit framework are easily automated.
DbUnit's elegant design makes learning how to properly utilize its features a breeze. Once it's in place as a part of an effective testing strategy, overall code stability will increase dramatically, along with the collective confidence of your development team.
