Methods and apparatus for testing software with real-time source data from a projectile according to various aspects of the present invention operate in conjunction with a real-time data source, a signal processor, a recordable medium, and a testing platform. The signal processor receives real-time data from a real-time data source during a test and saves it to a storage medium before providing the real-time data to the testing platform for permanent storage. During a subsequent test, the testing platform may upload the saved real-time data to the signal processor foregoing the need to generate new real-time data from the real-time data source.
