ABSTRACT:
A device emulator for use in testing pre-release program code emulates and replaces a first storage device such as a SCSI CD ROM drive containing the program code on CD ROM with a second storage device such as a SCSI hard drive. The emulator receives SCSI commands from an SCSI bus from a target system intended for the first drive. Through use of an emulator library, the emulator effects reads from the second device as if they were from the first device, and places the result on the SCSI bus. Testing personnel are thereby enabled to test the code on the second device which essentially behaves as the first device without the necessity of awaiting production and distribution of CD ROMs containing the test program code.
