Methods and apparatuses are described for testing a modified version of a software application. A recorder module stores production incoming messages received by the software application and associated timing data; production outgoing messages sent by the software application and associated timing data; a sequence of random number values and associated timing data; and a plurality of production event registrations by the software application and associated dispatch timing data based on an actual dispatch time associated with the production event registration. A playback module sends production incoming messages to the modified software application; receives and validates test outgoing messages from the modified software application; sends the sequence of random number values to the modified software application; receives and validates test event registrations from the modified software application; and sends to the modified software application a dispatch message to dispatch an event associated with a test event registration.
