DEVICE, METHOD AND PROGRAM FOR PERFORMING SYSTEM TESTING

摘要

In an approach for testing the operations of a host system during a host system migration, a terminal agent exchanges messages already exchanged between the current host system and a terminal with the new host system. A manual operation replay unit replays messages generated by manual operations among the messages sent to the current host system by the terminal. An automatic response unit automatically generates a response message for messages received from the new host system. The automatic response unit also generates screen data for a screen displayed on the terminal on the basis of messages received from the new host system. A comparison unit compares and evaluates screen data generated by the automatic response unit and screen data from a screen generated by the terminal on the basis of messages received from the current host system.

1. A method for testing operations of a host system during a host system migration, the method comprising the steps of:
testing, by a server, the operations of the host system after the host system migration to perform an exchange of messages with the host system after the host system migration; generating screen data for a screen to be displayed on a display unit of a terminal on a basis of the messages received from the host system after the host system migration; and comparing the screen data generated on the basis of the messages received from the host system after the host system migration to screen data generated by replaying the operations of the terminal on a basis of the messages exchanged with the host system prior to the host system migration to determine whether or not there is a match; the step of exchanging the messages further comprising the steps of: retrieving and reproducing messages from files created by extracting the messages generated by manual operation of the terminal among the messages exchanged between the host system and the terminal prior to the host system migration, and sending the reproduced messages to the host system after the migration; and automatically generating response messages for requests when the messages received from the host system after the host system migration are messages requesting a response, and sending the generated response messages to the host system after the host system migration, and sending replayed messages after the generated response messages have been sent.
