/**
 * Example test for {@link PersonSearchDAO}. The two files
 * personin.bin and personout.bin are snapshots
 * from a real mainframe communication. Once created, the snapshot
 * files can be used to simulate mainframe access in tests.
 * The personin.bin file represents an empty person with an id of 
 * 1, which is the request. The personout.bin contains the 
 * user data for the person with id 1. If we search for a user with id 
 * 1, the framework recognizes that the actual request matches the expected
 * request and returns the actual response (the personout.bin data).
 * If we pass 2 as the id, no response is found and findPersonById
 * returns an empty person. This example uses the
 * {@link com.mockrunner.connector.StreamableRecordByteArrayInteraction} which
 * works with byte data. {@link com.mockrunner.connector.StreamableRecordByteArrayInteraction}
 * can always be used when the involved Record classes implement
 * Streamable.
