* The test injector factory provides dependency injection of a contextual
* entity manager using the support/inject mini framework. It supports
* dependency injection of fields annoted with
* @PersistenceContext
. It only supports one persistence
* context at the moment. This injector can be easily used together with
* {@link JpaBuilder#getContextualEntityManager()} for obtaining an entity
* manager in unit test.
*
* The reason it is needed is because standard injection mechanisms (such as * weld CDI) do not support entity manager injection in a Java SE environment * out of the box. *
* *
* To use it, construct the factory using one of the available constructors and
* set InjectorBuilder.setInjectorFactory(InjectorFactory)
.
