Claim:
A method of verifying a transaction conflict operation of an information processing apparatus having a processor and a memory, by using an I/O emulator, the method comprising the steps of: forming test instructions from a test program executed by the processor; forming I/O emulator script commands to be executed by the I/O emulator and being related to the test instructions, from the test instructions; executing the test instructions and generating each transaction from the processor; and executing the I/O emulator script commands and generating each transaction from the I/O emulator. wherein the test program runs on the information processing apparatus, and wherein the information processing apparatus has a plurality of nodes each having a plurality of processors, a plurality of I/O emulators and a memory, each processor of each node executes the test instructions and generates each transaction, and each I/O emulator of each node executes the I/O emulator script commands and generates each transaction.
