Class DefaultUnitilsTransactionManager

java.lang.Object
  org.unitils.database.transaction.impl.DefaultUnitilsTransactionManager

All Implemented Interfaces:

UnitilsTransactionManager

public class DefaultUnitilsTransactionManager
extends Object
implements UnitilsTransactionManager

Implements transactions for unit tests, by delegating to a spring PlatformTransactionManager. The concrete implementation of PlatformTransactionManager that is used depends on the test class. If a custom PlatformTransactionManager was configured in a spring ApplicationContext, this one is used. If not, a suitable subclass of PlatformTransactionManager is created, depending on the configuration of a test. E.g. if some ORM persistence unit was configured on the test, a PlatformTransactionManager that can offer transactional behavior for such a persistence unit is used. If no such configuration is found, a DataSourceTransactionManager is used.
