.. includecode:: ../../../akka-persistence/src/test/java/akka/persistence/fsm/AbstractPersistentFSMTest.java#customer-apply-event
``andThen`` can be used to define actions which will be executed following event's persistence - convenient for "side effects" like sending a message or logging.
Notice that actions defined in ``andThen`` block are not executed on recovery:
.. includecode:: ../../../akka-persistence/src/test/java/akka/persistence/fsm/AbstractPersistentFSMTest.java#customer-andthen-example
A snapshot of state data can be persisted by calling the ``saveStateSnapshot()`` method:
.. includecode:: ../../../akka-persistence/src/test/java/akka/persistence/fsm/AbstractPersistentFSMTest.java#customer-snapshot-example
On recovery state data is initialized according to the latest available snapshot, then the remaining domain events are replayed, triggering the
``applyEvent`` method.
