A transaction system emulator serves to emulate various transaction system peripherals, replacing each emulated hardware peripheral by a corresponding software counterpart and an interconnection between the computer performing emulation and the transaction system hardware. Thus, one or more input devices (102) are replaced with logs of input data (105) such that the system being emulated can be tested without requiring a significant amount of input test data to be manually entered. Sets of test data may be captured either utilizing the emulator system with actual peripheral input devices (102), or obtained from an actual transaction system including such input devices. Alternatively, input test data logs (105) are created by other means, such as by a program, text editor, or the like. An output log of data resulting from input test data is created and, if desired, compared against a log of known, valid data corresponding to the input test data. |
