Jitr improves your integration testing process by enabling:
Integration : Run the same integration tests from Ant, Maven or the same IDE as you run your unit tests.
Unique ports for continuous integration : Jitr assigns a random, unused port for your container.
In-memory database access : Manage an in-memory database that your web application has created.
Spring application context sharing : Share the same Spring application context and beans as your web application.
Runtime flexibility : Switch containers and Spring application context configurations at runtime for robust and complete integration tests.
Extensibility : Use one of Jitr's wrappers around your favourite container or easily write and use your own.
